We launched this blog to share what we learn on real production lines, the small material decisions — from entry board to backup board — that decide whether holes come out clean or burred, and whether your drill bits last a shift or a week.

We launched this blog to share what we learn on real production lines — the small material decisions that decide whether holes come out clean or burred, and whether your drill bits last a shift or a week.
If you are new to the drill stack, start with what a PCB entry board is — that first contact surface decides how cleanly every hole begins and how long the bit lasts.
The same logic applies underneath the panel, so the material comparisons also cover what a PCB backup board is and how its grade controls exit burr.
