To all, For purchased components we impose solderability requirements of J-STD-002 on our suppliers. Most of the time we use these purchased parts in a timely manner and do not experience solderability problems. More recently, however, we are having to make decisions about whether or not we can use components from stock that are 1-2 years old. There seems to be some confusion within my group as to whether or not "solderability testing" needs to be performed to determine whether these parts are still solderable. In reading J-STD-001B para 5.2 Solderability, the last sentence says "When a pre-tinning and inspection operation is performed as part of the documented assembly process, that operation may be used in lieu of solderability testing." Based upon this statement, would it be acceptable to tin and inspect a sample of each aged lot based upon an established sampling plan (that we would create) Vs having to go through the riggers of solderability testing per J-STD-002. Based upon what I have read it appears that we will in fact need to validate the solderability of these parts based upon their age? Any clarification would be welcome.
