Technical Overview of Flex Mitigation Solutions

Flex cracks have been known in PCB manufacturing for quite some time. Flex cracks are created in capacitors when board flex stress / bending stress is applied to a circuit board with ceramic components already affixed to the PCB. As the ceramic capacitor is inherently hard, non-elastic, and brittle (relative to the PCB), any bending of the board creates stress, and that stress can be transmitted through the solder joint, directly to the ceramic body. This stress must be relieved somehow � and this stress relief can result in the creation of a board flex crack

Best, Inc instructors have put to video demonstrations of common hand soldering skills. These are not designed to be in place of live one on one training where repetitive skills and subsequent one on one feedback is given. Rather they are quick refreshers designed to be viewed if a specific skill has not been practiced in a while.
