Solder Testing


Solderability is a test to determine if the components will have soldering issue at the contract manufacturer.  Especially with old date code components leads can have oxidation.  This will caused components not be able to solder to the board.  As the result you will have mechanical failure which will delay the CM process and increase cost.  It is recommended that all lead devices that are more than two years old shall subject to Solderability test.
