This article, devoted to the importance of PCB checks, shines a light on the most popular PCB testing methods and their application in circuit-board design and production.

Ideally, a board should have a test point for every node in the circuit, and the 100% probing access makes it possible to evaluate every component on the printed circuit board (PCB).

All this means that with an UUT connected via pogo pins to a through-hole only test PCB, the full circuit would be completed, if and only if the UUT was completely functional, and that means ...

Test engineers struggle to find the optimum balance between printed-circuit-board (PCB) cost and test coverage. Low coverage leads to excessive field returns, warranty replacements, and even lawsuits.
