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.

More than 350 engineers who attended last week’s IPC webinar, Soldering and Assembly Defects, were polled on their biggest headaches with printed boards, PCB components and PCB assembly process failures. The survey results which identify solder finish, ball grid array (BGA) components and reflow soldering as the greatest challenges, provide webinar co-sponsor, National Physical Laboratory (NPL) of the United Kingdom with useful information as it prepares its NPL Process Defect Clinic for IPC APEX EXPO® 2012.
