Wow, John.  I would love to use those criteria.  Realistically (for us, at least), we have found through experimentation that no more than 10 days between the 2nd reflow cycle and wave soldering yields acceptable quality.  Of course, the less time the better.

I would say within 2 back to back 8 hour shift cycles (or 16 real time

hours) which is what I use as a rule of thumb for both OSP and silver.

Everyone,



What is the maximum recommended time to complete all reflow and wave

soldering cycles on product that is coated with OSP?



I'm trying to establish a guideline for my facility and can't seem to

find a lot of related information on this subject.



Thanks in advance for your input!
