J-STD-001 doesn't necessarily require additional controls under conditions of low humidity, only that you verify the effectiveness of what you have in place. ESD S20.20 [1999] only says that relative humidity above 30% is "desirable". ESD S20.20 [200

Defining the thickness of solder between the lead and the pad, J-001 states "Properly wetted fillet shall be evident." J-001 is available from http://www.ipc.org. Factors that affect this are: * Amount and composition of solder * Amount and compo
