The Standards of Design
Our expert contributors discuss how PCB designers can utilize standards to save time and money, not to mention frustration. We also spotlight the newly updated version of the IPC Checklist, a handy guide that illustrates which standards cover which topics, from front-end design through assembly.
Rigid-flex: Designing in 3D
In this month’s issue, our expert contributors share their best tips, tricks and techniques for designing rigid-flex circuits. If you’re a rigid board designer considering moving into the 3D world of rigid-flex, this issue is just what the doctor ordered!

DFM 101: Cost Driver SummaryJune 8, 2023 | Anaya Vardya, American Standard Circuits
Estimated reading time: 1 minute
One of the biggest challenges facing PCB designers is in not understanding the cost drivers in the PCB manufacturing process. We will wrap up this DFM series with a summary of cost drivers that impact delivery, quality, and reliability. It is categorized by low-, medium-, and high-cost adders.
Low-cost Adders (< 10% board cost)
Complex routing and scoring mean a small increase in process time, but a process is still required which will be driven by NC programming; it may limit tool life as a function of diameter. Thicker or thinner PWBs (>0.093", <0.030") means a material cost variation but it is minimal. Via plug or button print requires a small process change to the screen-print mask dot.
Medium-cost Adders (10–25%)
Regarding drilled hole quantity, there is a cost adder for high-density design-driven hole count and process time. With smaller drilled hole size, the small drill diameter (<0.010") limits throughput and stack height.
Embedded resistors with Ohmega/Gould technology will need additional core testing and finished board verification. Non-FR-4 materials, like PTFEs, can be 10 to 20 times the FR-4 cost, and material cost is generally 25–50% of the board cost. Edge plating will have additional processes required prior to plating.

The goal of the collaboration is to promote the standardization of post-quantum cryptography.
Nordson Electronics Solutions, a global leader in electronics manufacturing technologies, is pleased to announce the release of the new ASYMTEK Select Coat® SL-1040 conformal coating system.
For sellers, the whole process is relatively simple: They may say it’s not just about the money, but in truth, it is. Sellers also want a quick process, most of their money upfront, and a reasonable expectation that any deferred compensation will actually be paid. They’re usually concerned that the buyer will take good care of their employees, customers, suppliers, and other stakeholders, and that the seller’s responsibilities after closing, if any, be acceptable. But what do buyers expect? A lot.
I am, at heart, a die-hard “Star Trek” fan. When I was a kid, I was all about phasers, warp drive, and cool stuff like that. However, these days, I tend to put a higher value on production and storytelling. But like any fan (I’m avoiding “Trekkie” because, frankly, it’s kind of embarrassing), I have certain moments from the hundreds (if not thousands) of hours filmed for the various TV shows and movies that are among my favorites. One of those moments is in “Star Trek III, The Search for Spock,” when our heroes steal the Starship Enterprise from space dock.
While previous industrial revolutions have introduced factories, mass production, and computer-controlled systems, the advent of Industry 4.0 and the concept of the Smart factory have ushered in a new era in PCB manufacturing. For the PCB industry it is a very ambitious and aspirational objective to evolve from disconnected processes to an integrated system with automated data capture, real-time data analysis, process visualization, autonomous control, and self-correcting processes.
