HotPCB has pointed to and written about the relationship between fabricators and designers since our inception.  And we are not the only one speaking to it.  Pete Waddell of UP Media wrote an editorial to the issue of DFM (design for manufacture) failures within our industry earlier this year.  We would like to speak to the issue as well, but not without providing a way to begin fixing the problem.

The issue is that there has been, and will continue to be a disconnect between printed circuit board designers and fabricators.  If you, as a designer, have a firm grasp of the details surrounding the fabrication process, power to you and thank you.  However, if you are a designer and have not spent time learning the process of building boards, I highly recommend it.  Now I understand that the two parties have their areas of expertise, and I am not asking you to do a 9 month apprenticeship in a board shop.  But some research, and using some valuable tools available will be very beneficial to you.  How?  Read on.

Whenever a board comes into our shop, we need to check it for manufacturability and errors.  We use a variety of methods, but one of the key methods is to run the designs through DFM software.  We estimate that about 50% of the jobs we process need to go back to the designer for edits and changes after it has been run through the DFM.  That means we need to call/email the engineer, often leave a message, set up a time to talk about the issues, have them go fix the problems, wait to receive the updated files, assure that we don’t accidentally use the old files, re-check the design files, and then continue on in the production process.  In a quickturn shop, this may take 1-2 days, and I have heard several claim they often see it taking 5-7 days to get this all hashed out.  In a tense, quickturn market, several days means that you have doubled the lead time which was originally possible.  In addition to this, the fabricators are spending a lot of time going back and forth, chasing down engineers, revisions, files, etc.  This is time that is not billed, but in the long run finds its way into your boards because the process is less efficient and is using a lot of man-hours.  And so the designers are delayed in getting their boards, the fabricators are spending a lot of extra time pre-production, and nobody wins.

My hope is that there would be an industry wide shift in mentality toward an attitude of responsibility on the part of all to check for manufacturability.  I believe that it ultimately rests on designers to begin this change, and recognize that they can run preliminary DFM checks on their designs.  It takes very little time to run it, especially compared to several days of back and forth with the fabricator.  With designers running preliminary checks, and fabricators running secondary checks, the process will grow to be more seamless and productive.

One company in the marketplace who has narrowed in on this issue is Intercept Technology.  Their top-end software contains a DFM program, and their goal right now is to make it as accessible to designers as possible.  In fact, for a limited time it is free.  I recommend this to everyone within the industry.  This is an incredibly valuable tool for designers.  Together we can help each other accomplish our goals and increase in efficiency.  Designers will get their boards more quickly, fabricators will be able to spend more time improving their processes and building boards, and greater understanding/collaboration will be fostered between both.

Do you have a DFM nightmare story?  Or a success story?  Please feel free to comment below.  Maybe you think this is all hot air and unnecessary.  I’d like to hear what you have to say.

Although plenty of part numbers go through our shop which are classified and their end use is unclear, it is still quite possible to recognize the end users and the importance of performing quality work.  Products, processes, and chains are only as strong as their weakest link; and narrowing our focus too far on one spot in the product development cycle can have catastrophic consequences.  Our company, Cirexx International, does a fair bit of work within the defense industry.  For this reason, I will use the following hypothetical example as a reference.

“Although PN xxxxxxx is a simple 6 layer rigid-flex, it plays a critical role within a hand-held communications device our warfighters in Iraq rely on and expect to be functioning regardless of extreme conditions.  It’s failure, delamination, improper design could mean life or death for a whole troop.  And we all know who our military serves… us.”

If we focus on and remember who our end user is, the technical nature of our boards, our workplace morale, and our general business practices will all be affected.

Technical
If we were to keep in mind the big picture of who we serve with our products, many technical aspects of our products would be affected.  Most notable, I believe quality and quality assurance would improve.  Technicians, managers, suppliers, etc would all hold themselves to a high moral standard above and beyond their ISO or corporate quality mandate.  Responsiveness to issues and concerns on the part of the customer would increase.  Recognizing that each delay in the product life-cycle keeps a potentially life-saving product out of production and out of the hands of our soldier, nurse, pilot, etc for a greater period of time.  Paperwork and voicemails will have less likelihood of being put off until the afternoon, the end of the week, etc.  And lastly, collaboration will improve.  Although it is not necessarily the job of the lamination technician to determine proper materials for use in the final product, they may have some knowledge of past performance that the designers did not.  Whether it’s that they heard from a colleague that a particular thickness of laminate has been having issues in extreme temperatures, or in humidity.  Knowing that the board will be in a product in use in the rain forest may happen to be a huge help.

Workplace Morale
Not only will the technical integrity of your boards increase, but also workplace morale and spirit.  Employee sense of ownership and duty will grow when their understanding of the big picture increases and the tunnelvision we often fall susceptible to is countered.  This will lead to increased attention to detail, greater job satisfaction, and a greater sense of community within your organization and between organizations.

Business Practices
Lastly, recognition of the true impact your company’s product has will lead to changes in how your business operates.  Customer service and support will take greater precedence.  Also, capital improvements and research/development will take greater priority.  Recognition of the ways we need to remain competitive, and provide the most cutting edge products to our customers will occur when we step back and think about the importance we play in the lives of so many people.

Who are your customers?  Your real customers… probably people who have never and will never hear of you.  Yet it is them who you serve, it is for them that we work day and night, providing the highest quality products with the best customer support and responsive attitudes possible.

What other improvements do you feel would occur if we were to all continually remind ourselves of these things?  Feel free to comment below.

I have spent some time exploring the virtual show floor and various exhibits.  My gut response? I miss shaking hands.

A virtual trade show has some great benefits.  The reduced costs associated with travel is the first to come to mind.  There is also the advantage of being able to go about your day at work, and to hear a notification that someone has stepped into your “booth”.

However, my first interaction with a virtual show hasn’t been the best.  Please do not read that as a condemnation of virtual shows.  I just don’t fit the description of someone who would truly benefit from this show.  It seems that this style of show (virtual) really weeds out the moochers.  What I mean is – there are a few very specific strengths of the show, and if you fit within the target of those strengths, it will be great.  However, if you’re on the fence, you won’t like it.

With 2,300 attendees, Virtual PCB has been great for the exhibitors.  Many have stated that their booths have been consistently busy.  And it would be awesome to be an attendee looking for some services provided by the exhibitors.  The ability to switch in between various companies and instantly chat with them is great.  Exhibitors also have access to attendee lists, which is a very valuable resource when used correctly.

But for me, as a competitor to most of the exhibitors and being a marketing guy without technical expertise, there was not a whole lot of benefit.  Had we exhibited, I might be singing a different song.  This is a great benefit for the exhibitors… having a firewall/deterrant of sorts to their competitors.  There is very little cherry-picking.

What are your thoughts or experiences concerning virtual shows?  They are definitely a piece of the puzzle as it relates to the future of our industry.  UP Media is leading the charge, and sincerely I commend them.  Did you find the show helpful?  Are there aspects you wish were different?

The year 2009 has been an intense crash-course and immersion into the PCB industry.  I entered the field having only seen a board in settings such as when my mother’s blender lay torn apart on my lap as I sought to “fix” it as a ten-year-old.  My background is in entrepreneurship and business development.  Keep these things in mind as you read, but I hope that you do not allow them to lessen the various observations.  Please be sure to comment, critique, and add to this article in the comments section.

Market Segments
Tradeshows
There is nothing as bittersweet as a tradeshow.  It is easy to see that while many I’ve spoken with claim to dread the show circuit, there is an industry sustaining vibrancy found on the tradeshow floor.  In fact, regardless of size, shows remind many that they are not alone in this economic climate and in this industry.  “How about them Yankees” was definitely replaced by depressed and rehearsed comments about overseas production and its implications.  Yet even competitors can console one another.

Recessions inherently bring about budget cuts and a careful critique of the ROI (return on investment) of all marketing endeavors including tradeshows.  Smaller displays with fewer freebies seemed more prominent as the year progressed.

However, tradeshows will never go away because there is an inherent need within any industry to foster community and to provide convenient platforms for vendors and customers to interact.  Yet there is a great need for training and planning of employees to occur in 2010.  Pre and post-event networking skills need to be developed.  And it seems clear that the question of whether we will attend the next tradeshow is moot until we have exhausted an investigation of how we can best take advantage of the opportunity contained within each show.

Media and Trade Publications
As a complete rookie to PCB’s, I found the press to be my greatest ally.  Wonderful individuals within UP Media and  iConnect007 greatly encouraged and guided me through year one.  In fact, they are both the customer and supplier’s greatest asset.  Many of the most knowledgeable individuals are connected with these organizations and an email to either requesting direction or a good contact will usually turn out well.  Don’t expect them to play favorites or violate privacy issues, but they will do their best to direct you toward professionals or resources which will aid you greatly.

Political Climate
Changing the political landscape concerning any issue is always a laborious and time consuming process.  However, great strides were taken this year as the position of PCB Executive Agent was created.  In the second week of December, close to one hundred twenty-five industry professionals gathered in Washington D.C. to discuss how we can meet the needs of the Department of Defense in the future.  It was great to see so many key organizations represented and to see that many CEO’s and owners attended personally.  If there is to be a single word that must define 2010, it will be collaboration.  The IPC Technology Interchange in Washington was a great step toward that end.  I will discuss collaboration in greater depth shortly.

Customers
Throughout the year I sensed a continual increase in both the loyalty and price consciousness of our customers.  It was great to see the loyalty exhibited by many of our best customers, while it was tough to see quotes lost on price: even a few dollars.  Budget cuts have made it hard for everyone, and it is understandable in most cases why these occurred.

Although the following recommendation is applicable to every year within a business, I feel 2010 demands an even greater attempt.  It is clear that better communication and collaboration could and should occur between customers and the design, fabrication and assembly providers.  My hope is to personally continue to search out ways we can better serve our customers  (based on what they say, not what we assume).  This is crucial; especially for the small domestic board shops and assemblers.

Praises and Hopes
I have seen several people step up and push the envelope this year.  Some have exhibited customer service above and beyond expectations, some have embarked on innovative marketing and sales endeavors, and several faces have gained recognition as they position themselves as experts within their niche.  Below are some of the ways that they have accomplished these things.

Online Resources
Those who have met me this year most likely know about my passion for seeing the industry catch up with the rest of the private sector in regards to leveraging the tools and resources available online.  There is much to be done, but I am pleased with the small steps taken this year.  The year 2009 exhibited an increased number of companies transitioning to online marketing and advertising.  Several new columnists have appeared for various media organizations and the concept of blogging is beginning to make sense to some.

I continually experience excitement over our endeavors to develop an industry blog, yet see little follow through.  Although much of that may be due to the quality of my efforts, I do hope to see increased support and contribution in the coming year for HotPCB and my colleagues who are pouring their energies into online media.

I was given the opportunity to speak at UP Media’s PCB Atlanta in October on the subject of how the PCB industry can effectively leverage the various Web 2.0 tools currently available.  Those in attendance seemed to find it helpful, and it was a great first step.  I challenge both individuals and organizations to sit down and evaluate how they can implement these tools into their various marketing and sales strategies.

Federal Programs
This year’s Federal Matchmaking event in Tarrytown, NY was extremely well attended.  I highly admire the SBLO’s and various individuals who spend their time making sure that small-business allocated opportunities are distributed.

The PTAC officers and employees really stepped up and it was very apparent how much they desire to foster commerce between small/disadvantaged businesses and the government.

Education
There is a huge need for education within the industry.  And yet, providing resources to seasoned veteran is far from enough.  Unfortunately, the industry is graying, and there is no clear next generation.  Some have recognized the massive vacuum that is forming and are investigating the feasibility of teaching electronics at the high-school level.  This is a movement still in its infancy and needs a lot of support, guidance, materials, and commitment.  That is where collaboration will truly show its worth.

Collaboration
As promised, I want to briefly touch on collaboration once again.  It has been said that when everyone is responsible, no one is responsible.  I saw a lot of great concepts discussed at the Technology Interchange.  There has been a lot of hard work on the part of various individuals.  We as an industry need to be very careful that we don’t simply sit back and applaud their work.  A concerted effort should be made by all.

Change is a slow process.  But it is even slower when there are only a few players.  My hope is that 2010 will be a year marked with collaboration, unity, and change.  We have all seen glimpses of where things could go.  And although it is unlikely that things will ever look like they did twenty years ago, I find it highly likely that this industry will take huge leaps forward in the next twelve months.

In ending, I am very thankful for where I am, and where we are.  Great hopes drive my endeavors and will continue to shape my efforts.  Where do you see yourself making a difference?  What unique skills can you bring to the table?  How can we come together to overcome the various challenges that are facing our industry?

2010, here we come.

This is a complex question with a large number of factors.  One focus of the discussion could be on the pure technical limitations which will be reached according to the laws of physics, or you may consider the unlikelihood that we will ever meet a need that PCB’s can’t handle due to the high costs which would surround that new technology.

I hope to hear your input and comments.  Where do you see the technology going and needing to innovate?  How do you see system-in-a-package and 3D Integration being a factor?  I don’t even have all of the appropriate questions surrounding this topic, but I hope that the comments below will be full of insight and discussion.

Thanks!!

P.S. Someone should add to the wikipedia article about system-in-a-package.  It could use some help.

Education?
The first question that you might ask yourself is whether this is something for which you can go to school.  I approached Bill Brooks of Datron World Communications, who in the past has taught classes at Palomar College in PCB Design and Advanced PCB Design.  He was introduced into the field because his father owned a board shop where he worked until he was nineteen.  Bill echoed what I have heard from many:  that traditionally designers do not have college degrees.  A four-year degree, let alone a Masters, is not needed to be successful.  However, the technology continues to advance and designers must be much more rounded and have a greater understanding of a wide variety of variables than they did even only ten years ago.  I also spoke with Rick Hartley of L-3 Communications.  He is an accomplished designer and teaches technical seminars at various trade shows around the country.  He echoed the same sentiment.

Although various classes are available, the most valuable training is found within a mentorship relationship.  Rick learned how to design because a co-worker and mentor took the time to teach him.  Do you wonder where you can find a mentor, or the academic resources to succeed?  Fortunately there are a variety of places for you to go where you can receive training and meet designers who would love to teach you, especially if you are a younger entrant into the field.

If you are truly interested in making it in the field of PCB design, you must immerse yourself and strive to become an expert.  Let’s break it down into three approaches.  You need to network with current designers and find a mentor(s), you need to attend technical workshops and training sessions, and there are a few must have books that you ought to read.  Let’s start with networking.

Networking
The IPC is a very well recognized organization worldwide and they host online communities called Designer Councils which are divided up geographically.  Some of the most active councils are in Orange County and Portland.  You have a great opportunity to connect with and meet in person designers who would love to help you learn.  Although slightly archaic in their technology (they use list server technology), this is a very valuable tool and will allow you to connect with thousands of professionals.  the IPC recognizes the need to cultivate new designers and is actively pursuing programs to do just that.  Also, check out the article Best and Worst LinkedIn Groups for PCB Enthusiasts.  Use the connections within those groups, the discussion boards, the Q&A section, etc to meet and interact with experts.

Technical Training
Board design has gotten more complex as the devices they power have pushed the limits.  Although the printed circuit board has not changed significantly in its build over the last 35 years, the environment into which it is placed has.  Designers must understand electronic theory at a technician level, understand the PCB fabrication process, mechanical stress and how to prevent failure modes, the assembly process, testing processes, what the board is going to end up in for additional variables, and must also be cost conscious when it comes to materials.  Does this sound overwhelming?  Fortunately there is a plethora of design shows where you can attend technical sessions pertaining to all of these issues.  There are the IPC and Design Conferences, UP Media group’s PCB shows, designer council meetings, webinars, blogs, and companies that offer training courses.  Follow the various links and explore the opportunities to receive training.  The best training Rick ever recieved was a week long session about “board design for productibility.”  Seek out similar courses and seminars, and  you will do great.

Read, Read, Read!
If you want to be the best, you need to read from the best.  I have taken suggestions from several experts regarding what books they feel are the best for you to read if you’re seeking to expand your knowledge of the field.  I have listed them in the bookstore section of HotPCB.  Do us a favor, if you purchase through our links we might make a dollar.  That’d be cool.

I ended  all of my interviews asking if they had any predictions of where the industry was going, or what they would say in closing to someone just getting started.  Rick made the point that there are going to be a lot of available jobs and to get into it now.  In the long run it will pay off.  He took a pay cut when he first went into design, but quickly surpassed his former income.  Many designers are going to be retiring in the next 10 years, but PCB’s aren’t going anywhere.

Cheers!

In addition to a large number of PCB enterprises in Taiwan, many PCB operations are located in Jiangsu, Zhejiang and Guangdong provinces.

Among them are leading PCB makers earning hundreds of millions of dollars in annual revenues and employing thousands of workers.

They also spend huge sums on environmental protection, including the disposal of manufacturing wastes from production processes and everyday operations.

The major pollution source of PCB industries is the copper content in the spent etchant and wastewater streams.

Traditionally, liquid resin is used to chelate spent etchant, forming copper ions and converting them into a copper sulfate solution for industrial applications.

Although this process can recover most of the copper from PCB waste streams, a considerable amount of the metal is unrecoverable. This metal is discharged into the environment, which can cause severe water pollution problems.

For any major plant, the daily amount of wastewater, along with untreated sludge, can total thousands of tons. This wastewater and sludge contains copper and also lead, tin and other metals used in soldering processes.

Stricter environmental protections adopted in recent years have forced PCB manufacturers to seek new technologies to promote better, yet cost-efficient waste recycling methods.Shortly after the State Council announced its 4 trillion yuan stimulus package to boost the domestic economy, attention turned to reviving industrial sectors battered by the ongoing global economic crisis.

During a series of meetings by the State Council in January and February this year, an “industrial restructuring” policy was adopted that focused on “10 key sectors.” The PCB industry is among those key sectors.

The government asked that PCB manufacturers focus on two elements: cleaner production (CP) and a circular economy (CE) to make this industry environmentally clear and economically stronger.

A semi-annual PCB technical conference in May at Suzhou, Jiangsu province, answered this CP/CE challenge with green technology sessions and economic discussions.

Hundreds of Chinese companies were represented – all eager to learn innovative technologies and international market trends.

Papers were presented on energy-saving measures, emissions reductions and also proposed CP/CE practices.

Seven universities in Taiwan established an incubator to study “best practice” CP/CE applications at the Center for Innovation and Incubation at Chung Yuan University.

The center has invited the participation of industry representatives, academic institutions and the government.

A persistent challenge is the incomplete recovery of copper from plant discharges, wastewater and sludge.

A recovery procedure recently developed by Taiwan-based Trinity Resource Technology Inc has employed a CP/CE solution.

The procedure involves separating copper compounds from wastewater in a way that recovers most of the copper, resulting in near-zero discharge.

Through a chemical treatment method operated outside the plant premises, the recovered copper compound is purified to form copper oxide, which can be recycled and used in the PCB electrolysis process.

Trinity is working with Chung Yuan University to build a pilot plant employing this new procedure.

This new approach is an example of the innovation that is being sought by the PCB industry to produce useful, profitable and environmentally sound products.

With an eye to recycling, circuit boards are being used in asphalt

By Mark Fischetti

Millions of printed circuit boards from discarded electronics are tossed into landfills every year. In addition to the volume of waste, the material can leach chemicals into the soil. As an alternative, researchers at Shanghai Jiao Tong University in China are finding various ways to reuse the panels, including as an additive in asphalt.

Xu Zhenming and his colleagues stripped the boards of all components, pulverized the remains into a powder and used an electrostatic separator to remove fine bits of any remaining metals, leaving a pulp of glass fibers and resin. They then added those remnants to warmed asphalt, to see if the pulp would act as a binder. Binders such as ground tire rubber and charcoal are typically added to improve asphalt’s stiffness at high temperatures (to reduce rutting) and its pliability at low temperatures (to prevent cracking). The pulp improved both properties, especially when the powder grains were made as small as possible. Zhenming’s team is testing the modified asphalt to check how it holds up to outdoor conditions over time. It is also experimenting with forming the pulp into sheets that could be made into structures such as park benches and fences.
