PCB Reliability Testing: Methods for Ensuring Long-Term Durability

Written by Angie Brown
Posted on July 24, 2025 at 9:01 AM

When I first started thinking about printed circuit board (PCB) testing, my immediate reaction was boredom. Let’s be honest, it doesn’t have the hands-on excitement of building the circuit board itself. You're not designing the PCB; you're just running it through a tester, sorting it into a pass or fail bin, and moving on. I’ve done the job myself, so I know how repetitive it can feel.
