Target those specific parts/leads with a thermal-couple and a mole and try to get the peak reflow temps up to 225 C. It's not a cure but it will improve the apperance of the solder joints.

IPC-A-610E "Acceptability of Electronic Assemblies" addresses this specific issue as well as most others. This issue would be to what class (1, 2, or 3) your assemblies would be governed by.

I found IPC-A-610E, but I cannot find one online that I can view without purchasing. We do not want to pay for a standard we are not sure we will be able to use.

I found some useful information in a red line version of IPC-A-610E I uncovered with a quick google search, and I will see what I can find out about their standard of acceptability.

The IPC-610 class II spec is very reasonable. If they expect class 3 then make them pay for it....IMO

Is it correct that there is nothing direct in Class III documentation that states these boards should not be reworked? Whether these boards are allowed to be reworked is strictly a decision / agreement between assembler and customer . . . correct?

That's correct - IPC-610 doesn't tell you whether rework is allowed or not. That's a customer issue.

hey Jacki we are looking at going from SAC305 to SN100C, if your looking to save cost it's a cheaper option. have a look into it.

I am trying to decide what type of no clean flux I should use in our selective solder machine. We run both leaded and lead free and would like to use the same flux for both. What is everyone else using? Or do you have any recommendations?
