Detroit vs. Silicon Valley: What’s Driving the Proliferation of Automotive Electronics?
For the past several decades, modern cars have not changed much. They have four wheels, an engine, a radio (possibly even an 8-track) and seatbelts. Over time, however, cars’ electronics parts have evolved faster than any other part of a car with enhancements like power windows, power mirrors, seat heaters and GPS navigation.
Characterization of PCB Material & Manufacturing Technology for High-Frequency
Concepts like Industry 4.0, Internet of things, M2M communication, smart homes and communication in, or to cars are maturing. All these applications are based on the same demanding requirement—a considerable amount of data and increased data transfer rate. The aim of this paper is to develop a concept to use materials in combination with optimized PCB manufacturing processes, which allows a significant reduction of losses and increased signal quality.
Improved Design of Dry Film Resist Laminator for Optimal Transfer of Micron-sized Features
Since the inception of dry film lamination, the process of squeezing two hot rolls at their end axis points has caused roll bending. An innovative process has now been developed whereby the film is attached with a process that minimizes this issue and provides optimal, evenly dispersed heat and pressure across the entire surface of the panel. This simple and elegant design will ensure that the integrity of the resulting image will be ideal, as measured by the continuity of the resulting transferred traces and features.
Plating and Quality are Close Partners
A good plating manager is a seasoned veteran with many years of hands-on experience and probably an engineering degree. Bob Tarzwell sees firsthand how PCB manufacturers, without the proper plating shop set-up operations, knowledge and experience, adapt and accept poor practices as normal while they continue with poor quality processes—even after attempted corrective input from vendors and consultants.
Design and Manufacture of High-Voltage Electronics
This SMART Group webinar, presented by Ian Lake, director of engineering at Applied Kilovolts Ltd, and moderated by Bob Willis, explored the current technical barriers faced in high-voltage electronics design and manufacturing processes. Although he made it clear that within the timeframe of a webinar session he could only scratch the surface of the topic, Lake gave a valuable insight into basic concepts and drivers and set a perspective on current state of the art and future trends.
A Well-Designed Laminate Supply Chain has to Own It!
Suppliers must use industry knowledge, robust systems, clever software and total visibility to build a supply chain agile enough for any PCB fabricator. Consigned stock, local customization, regional hubs, short manufacturing cycles, controlled processes and highly evolved systems are just a few of the tools needed to develop custom fit solutions that flex and move with the needs of the fabricator and their customers. You can only design the supply chain when you own the supply chain.
An Update on the Rogers Material Supply Line
As part of a recent I-Connect007 supply chain survey, we found that RF laminate material can be very difficult to obtain. Rogers Corporation was named specifically in our survey as one supplier with a limited amount of material available. In fact, their delivery time was reported as being as high as 55 days for some materials at one point. In an industry where quick turnaround time is critical, this is one supply line that killed any hope of being quick.

Flexible, Stretchable, and Wearable: If You Can Dream it, You Can Create it!
We originally intended the June issue of The PCB Magazine to be centered on flexible circuits, but it quickly became apparent that we needed to broaden the scope and include all (well, at least some) of the new and exciting things going on these days in the world of flexible everything. As such, we have garnered a trove of authors, with much information to impart on the above mentioned.
ENEPIG: The Plating Process
In this article, George Milad talks about the complexity of the ENEPIG process, how it works, its requirements and the critical parameters that must be maintained in the ENEPIG line. He writes that shops that have good engineering and documentation of the manufacturing process, coupled with a dedicated, experienced ENEPIG operator that is backed by a capable analytical laboratory, run defect-free ENEPIG day in and day out.
Being Flexible in a Rigid World
With double-digit growth in the foreseeable future, flexible printed circuits (FPC), have found a tremendous niche as an enabler for various electronic applications. This trend is expected to drive the need to increase productivity while improving performance and reducing costs. Of course, in order to sell flex, one must tackle the unenviable task of metalizing these often difficult-to-plate materials.
Material Witness: How About that Technical Roadmap!
You may remember the movie "What About Bob?" If you do, you may recall the scene in which Bob (Bill Murray) confronts his psychiatrist (Richard Dreyfuss) and emotes, “I need! I need! I need! Gimme! Gimme! Gimme!” As I thought recently about some of the drivers that IPC and others have incorporated into their technical roadmaps, I feel a bit like that befuddled psychiatrist.
