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.

Printed circuit board testing has been around as long as printed circuit boards, also known as printed circuit assemblies and printed wiring boards. PCB technology started in the early 20th century ...

Why are test points a crucial element in developing a successful circuit? Types of test points available, and the different techniques that employ them. Electronic design has always been an endeavor ...

The importance of properly integrating test points into a PCB design. Test-point deployment considerations. When it comes to creating a modern electronic design, we live in both the best and the worst ...

The limited access afforded to circuit nodes by PCBs densely populated with tiny components seriously challenges traditional PCB test strategies. But while optical and x-ray inspection can help fill ...
