Reading time ( words)
In a recent survey, we asked the following question: What do you think is the most important thing a designer should remember when planning a new PCB design? Here are a few of the answers, edited slightly for clarity.
- Get any unclear or conflicting input resolved.
- That they are the point of synthesis where all conflicting disciplines meet—electrical, mechanical, thermal, reliability, and cost—and that they need to take responsibility for creating the best overall finished package that works.
- Each design has its own restrictions, and each design is a new challenge.
- Look at the complete picture and not just your own “small garden.”
- Things can change.

Gerry Partida, vice president of technology at Summit Interconnect, authored a technical paper, “Next Progression in Microvia Reliability Validation—Reflow Simulation of a PCB Design Attributes and Material Structural Properties During the PCB Design Process,” at IPC APEX EXPO 2022, and it’s worth revisiting. This significant paper on microvia reliability validation provides a summary of what’s been happening in the microvia fabrication arena, especially regarding the issue of latent defects in stacked microvias.

As the second in this two-part series, The Printed Circuit Designer’s Guide to... Thermal Management with Insulated Metal Substrates, Volume 2, by Didier Mauve and Robert Art builds on the material presented in the first book by describing up-to-the-minute products and design techniques for thermal management with IMS.
