Weiner’s World: March 2016
Sellers of equipment at the Shanghai CPCA event complained of continued poor business. This was especially evident amongst those selling to firms building boards for phones and other portables devices as indicated below. However, not all reports were bad. Major fabricators such as Wu's in China, not dependent upon HDI or flexible products, stated that they were "satisfied" with their current business levels.
Designers Notebook: Flexible and Rigid-Flex Circuit Design Principles, Part 4
All of the design rules for the glass reinforced-portion of the board (land pattern geometry for mounting surface mount devices, solder mask and the like) are now well-established. One unique facet of fabricating the rigid-flex product is how the flexible portion of the circuit is incorporated with the rigid portion of the circuit. As a general rule for multilayer PCB design, furnish a balanced structure by building up the circuit layers in pairs (4, 6, 8 and so on).
The Supplier View: An Interview with Hamed El Abd

Happy’s Essential Skills: Design of Experiments
Design of experiments (DOE) is one of the most powerful and influential engineering tools for product yield improvements, new products or processes development, or for problem solving. As mentioned in my last column, process problems led me to a career in printed circuits, and quickly solving those problems led me to a bonus stock award and a great life. Even though I knew nothing about printed circuit manufacturing processes, I was able to quickly find the root causes of all the problems and fix them. My secret? Total quality control (TQC), statistics, and DOE.

Mr. Laminate Tells All: CEM-3 Reinvents Itself (Again)—or, Atari Game Boards on eBay?
CEM-3 was unusual as the reinforcement was a combination of woven fiber-glass fabric and fiber-glass paper. The resin system was a dicy-cured epoxy resin yielding a Tg the same as FR-4 at the time, of 110–120°C range. Because it was all epoxy and all fiberglass, the properties were electrically identical to those of FR-4.
What a Long, Strange Trip it’s Been—and It’s a Long Way from Being Over
Harvey Miller has been in the PCB industry for more than 40 years, and he’s probably seen it all. I recently sat down with Harvey at a wine bar in Palo Alto to learn more about his history in the industry and where he sees it going forward. Harvey arrived wearing jogging shorts and running shoes. No surprise after what his doctor recently shared with him.
New Year, New Outlook for the Electronics Manufacturing Industry
As an advocate for the electronics manufacturing industry, my job is to educate and encourage policymakers to create a favorable legislative and regulatory environment for advanced manufacturing to grow and succeed. From that perspective, I think we should be proud of the significant progress we made in several areas in 2015.
All About Flex: Flexible Circuit Antennas
In our world of fabricating custom electronics, a circuit can generally be defined as “a path between two or more points along which an electrical current is carried.” The printed circuit board industry designs and fabricates an incredibly diverse set of rigid and flexible circuits. But it is also true this industry produces many parts that do not carry current between discreet points.
How North American Fabricators Benefit from Attending HKPCA
Two New Englanders in Shenzhen. It sounds like the title of a play, doesn’t it?

What is the Internet of Things and Why Should it Matter to Us?
It is often surprising how closely our science fiction novels and movies model the future. The Internet of Things (IoT) and big data may prove to be an excellent example of this phenomenon. Coined in 1999 by Kevin Ashton (the RFID standards pioneer), the IoT is one of the least descriptive monikers of all time for something very important in the history of technology.
Catching up with Gardien’s Rick Meraw
There are companies out there who are truly changing the world—companies who are making a dent in the universe, to quote the late Steve Jobs. Gardien is one of those companies. So much so that I like to catch up with them on a regular basis because they’re always adding something to their repertoire and it’s typically something that helps improve the way we handle quality assurance in our industry.
All About Flex: Process Controls for Flexible Circuit Fabrication
Manufacturers of flexible circuits use several chemical processes for fabrication. These processes are generally located in a common area of the plant because of facility requirements and environmental considerations. These chemical operations are referred to as wet processes.
The Associations Issue
Well, it’s the end of the year. How did that happen? It really is true that every year goes by a little faster. You young whippersnappers out there won’t know what I’m talking about, but just you wait and see. We changed it up for our December issues this year. Instead of doing a year-end review, we decided to devote this month to our associations and trade organizations—at least some, because when you start poking around, you will find there are scads of them.
