HI,

I'd like to inquire about the supply side market for commercial grade
components that meet the requirements of IPC/J-STD-002 re. solderability

Currently we do not specify any solderability spec for the purchase of our
electronic components.  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?
