In-circuit test (ICT) has been instrumental in identifying manufacturing process defects and component defects on countless varieties of populated printed circuit board (PCB) assemblies for more than ...
Printed-circuit boards used to be works of art, and the PCB designer was an artist as well as a technician. Components had many different shapes, sizes, and colors, and the traces connecting them were ...
In-circuit testers rely on bed-of-nails-type fixtures that give the tester access to every node (or net) of the printed circuit board (PCB). Using this access, the tester takes a divide-and-conquer ...
Various techniques—ranging from x-ray and optical inspection through functional electrical test—have emerged to shorten time to market and reduce test costs while maintaining thorough fault coverage.
