Digital Transformation: Optimizing Co-Design Across Multiple Domains

David Wiens, Siemens Digital Industries Software

Higher system speeds have necessitated consideration of signal propagation delay and quality not just within electronics, but through wire harnesses. Tighter form factors have minimized the typical “board in a box,” where a simple rectangular board had enough clearance that there were rarely problems. Rigid/flex circuits often stress cross-domain ECAD/MCAD design with their multiple stack-ups and bendability. And even if form/fit is achieved, high-performance systems with significant heat dissipation need to ensure adequate air/fluid flow through the structure.

Fresh PCB Concepts: How Large Does That Pad Really Need to Be?

Ryan Miller, NCAB Group

Annular ring is the amount of copper left and surrounding the hole after processing. This measurement is taken from the edge of the hole to the edge of the land at the thinnest part. To ensure a robust design, we must design efficient annular ring for PCB interconnections. From my field experience, annular ring design is a misunderstood aspect of printed circuit board (PCB) design. Not because it is complex; it is a dry subject with a few moving parts.

DFM 101: Final Finishes ENEPIG and IAg

Anaya Vardya, American Standard Circuits

One of the biggest challenges facing PCB designers is not understanding the cost drivers in the PCB manufacturing process. This article is the latest in a series that will discuss these cost drivers (from the PCB manufacturer’s perspective) and the design decisions that will impact product reliability. Final finishes provide a surface for the component assembler to either solder, wire bond, or conductively attach a component pad or lead to a pad, hole, or area of a PCB. The other use for a final finish is to provide a known contact resistance and life cycle for connectors, keys, or switches. The primary purpose of a final finish is to create electrical and thermal continuity with a surface of the PCB.

Supply Chain Management

In our August issue of SMT007 Magazine,“supply pain management" was the topic of discussion. This reminds us of the question that doctors often ask: “What’s your pain level on a scale of 1–10?”

Designers and design engineers have learned to navigate this supply chain craziness, snatching up components that are in short supply or making do with lower-tech parts that are available...
