Beyond the Rulebook
What happens when the rule book is no longer useful, or worse, was never written in the first place? In today’s fast-moving electronics landscape, we’re increasingly asked to design and build what has no precedent, no proven path, and no tidy checklist to follow. This is where “Design for Invention” begins.
March Madness
From the growing role of AI in design tools to the challenge of managing cumulative tolerances, these articles in this issue examine the technical details, design choices, and manufacturing considerations that determine whether a board works as intended.
Looking Forward to APEX EXPO 2026
I-Connect007 Magazine previews APEX EXPO 2026, covering everything from the show floor to the technical conference. For PCB designers, we move past the dreaded auto-router and spotlight AI design tools that actually matter.

iNEMI PCB Warpage Characterization and Minimization Webinar
April 17, 2020 | iNEMIEstimated reading time: 1 minute
PCB Warpage Characterization and Minimization End-of-Project Webinar: May 13?14, 2020
The use of thinner components and thinner multi-up panel PCBs (? 40 mils) has exacerbated PCB warpage issues in SMT assembly which, in turn, can negatively impact PCB assembly yield.
iNEMI’s PCB Warpage Characterization and Minimization project studied key design and fabrication factors for thin PCBs to determine the impact on warpage. The project analyzed the effects of:
- PCB post processing (bake & no bake PCB)
- Panel locations (corner & center)
- PCB thicknesses (0.8 mm & 0.6 mm)
- Material properties (mid Tg and high Tg)
- PCB fabrication processing
The resulting PCB warpage was evaluated using high temperature warpage measurement metrology to evaluate the ball grid arrays (BGA) and panel area PCB coplanarity. The project team will report on the analysis of the results and recommendations.

yieldWerx, WATS Partner to Bridge PCB Test with Chip-Level Manufacturing Data
05/11/2026 | PRNewswireBoard-level and semiconductor test data are often analyzed separately, limiting correlation across the product lifecycle. Linking PCB assembly (PCBA) test results, including in-circuit and functional test, with upstream wafer, sort, and final test data remains difficult, particularly in photonics, advanced packaging, and high-density integration environments.
