Hi Steve - The short answer to your question is NO! If you don't have an overall problem with solderability then "raising the bar" will only increase cost without reciprocal benefit. It sounds like you have the occasional, vendor specific solderability problem and no wide spread issues. Adding any specification requirements only makes sense if the additional requirements provide some benefit to the process or product for the extra cost or logistics that such requirements will induce. The reason for the extra cost for JSTD-002 components is the component manufacturers must perform a couple of additional tasks (i.e. solderability testing and documentation of those results) that are not part of their normal process flow. As for the changing of the component part numbers, that may have more to do with how the vendors track the component requirements - I know vendors that do not have "two" component numbers for a JSTD-002 or nonJSTD-002 component. The component vendors processes are just like the assemblers processes - nobody is setting up a process to produce "bad" product! JSTD-002 is a tool that the electronics industry can use as a baseline benchmark of comparison and as a tool for assuring a given level of solderability. If you are satisfied that the level of solderability you are receiving from your vendors is adequate for your processes and product performance then the 'addition" of more solderability requirements is not necessary.

We get many products that solder very well - both wave and hand with various fluxes(no clean - RMA - OA). Some parts are not so good - even mil spec. After talking with our major distributors it seems that the commercial grade parts that meet J-STD/IPC/Mil standards for solderability are not as available as straight commercial grade and will cost a bit more. They also said I would have to change part numbers - which would be a horrific task. Is this true or am I talking to the wrong suppliers? The second question is that given we do not appear to have a "problem" with most of our straight commercial grade parts, what gains could be made by sacrificing some cost and leadtime? No strong evidence exists that suggests a field performance / reliability concern. I can not see how I could justify "raising the bar", however many experts say that to change would be an improvement. Anyone have a practical philosophy on this dilemma that I can borrow?
