find the problem? Were the parts failing > electrically? Or did someone start prying them > and decide they were too weak? Originally found the problem going through some older assemblies that had failed testing. Poked at leads and found them no

Outstanding advice gentlemen! To borrow Dave F's line "I'd like to take a bit of a different angle." Ie. a few wave solder specific issues If this assembly is going over wave solder then avoid vias under passive components, it invites solder bal

Temperature cycling testing is a method of accelerated life testing done to PCCs that are exposed to normal operation temperature variations over its lifetime. During the testing, intermittent "open" failures can first occur at the hot and cold extremes of the test, exposing weaknesses in the design and assembly. A poor/weak solder joint fatigues, a via trace or barrel cracks, loose connections or a component fails all causing an intermittent open. When not at extreme temperatures, the PCC assembly relaxes, the "open" closes creating electrical connectivity. If you are monitoring the PCC under test in-situ you will know that an intermittent failure has occurred, and the test could be stopped for inspection. If in-situ monitoring was not implemented, you would not know if there were intermittent failures or not. The PCC gets powered up and works fine at room temperature.
