The Quest for Perfect Design Data Packages
There’s an ongoing problem in the PCB industry: fabrication shops are receiving incomplete or inadequate design data packages, leaving manufacturers scrambling to fill in the blanks. For a quick-turn prototype shop like Washington-based Prototron, with over 5,000 customers and up to 60% of orders coming from new customers each month, that can add up to a lot of wasted time and effort just in the quoting stage. Dave Ryder, Prototron president, and Mark Thompson, engineering support, delve into this continuing issue and more.

Managing the Challenges of Flex and Rigid-Flex Design
PCB designers working with flex or rigid-flex technology face many potential risks that can derail a project and cause costly design failures. As the name implies, flex and rigid-flex designs comprise a combination of rigid and flexible board technologies made up of multiple layers of flexible circuit substrates, attached internally and/or externally to one or more rigid boards. These combinations provide flexibility for the PCB designer working on dense designs that require a specific form factor. Rigid-flex allows the PCB design team to cost-efficiently apply greater functionality to a smaller volume of space, while providing the mechanical stability required by most applications.
Mechanism and Mitigation of Nickel Corrosion in ENEPIG Deposits

Do you spend time, as I do, musing on the language of PCBs? We have developed our own lexicon to convey as much by picture, as by word, what exactly we mean.
Study on Application of Four-Wire and Four-Terminal Flying Probe Test Scheme
With the four-wire and four-terminal flying probe test method, voids in the holes formed in the PCB due to process differences, thin copper, and poor conduction due to residual adhesive after laser drilling of the HDI board can be detected, and the circuit board guide can be solved. With the development of multilayer, high-density PCB layout, four-wire four-terminal flying probe testing will play an increasingly important role.
Advanced Copper Plating Process for Any Layer Via Fill Applications with Thin Surface Copper
Copper-filled microvias are a key technology in HDI designs that have enabled increasing miniaturization and densification of printed circuit boards for the next generation of electronic products. Compared with standard PTHs, copper-filled vias provide greater design flexibility, improved signal performance, and can potentially help reduce layer count, thus reducing cost.
Advanced Stackup Planning with Impedance, Delay and Loss Validation
A typical PCB design usually starts with the material selection and stackup definition—the stackup planning or design exploration stage. How reliable are the data provided by the material vendors and PCB manufacturers? Can we use these data to predict trace width and spacing for the target trace impedance or to calculate delays or evaluate the loss budget?
Susy Webb: Training the New Generation of Designers
For years, I’ve been running into Susy Webb at PCB West, where one of the classes she teaches is PCB design basics. I always ask Susy about the class, especially the attendees’ backgrounds. Over the years, her class has begun drawing more and more degreed engineers, with fewer “traditional” PCB designers attending. I asked Susy to discuss the next generation of PCB designers, some of the trends she’s seeing among new PCB designers, and the need for designers to take charge of their own design training, whether their management agrees or not.
Agfa: Staying Ahead of the Technology Curve
In the ultracompetitive electronics manufacturing space, companies that don’t continually evolve and invest in new technologies run the risk of being left behind. At the recent EIPC summer conference, many next-generation processes and technologies were discussed and even put on display.
