First question would be why are you hand soldering these resistors? I would expect ENIG to be perfectly solderable after reflow and quite some time later. If you leave the apertures out of the stencil and then decide to automate fitting them, you'l

I want to avoid peoples preferences as they will differ and will not be a deciding factor. A heat gun will introduce risk to surrounding PTH components and having to add protection for those, will limit any gain in productivity. There is no question

http://www.circuitnet.com/news/uploads/3/Comparing-Soldering-Results-of-ENIG-and-EPIG-Post-Steam-Exposure.pdf Years ago, I battled this problem. ENIG PCBs reflowed with active WS flux. We built one side, and then washed them because they were going

maybe someone can help me with this problem I have 4 S-20 machines on 3 lines and I notice that when I omit a component on the station computer other components are not assembled and on each PCB it's different components and not the same order. TN

Don't worry about the paste print. Just omit it from the stencil. Mask over all the SMT components after reflow with water washable WSOL masking. Then run it thru the wave to deposit the solder. Then wash to remove masking. Or you could manually run

(Hey Cal how you doing?) I can't resist this. You can sort of do what you're hoping for but you have to be very careful. Let the component run out and let the machine get as far as it's going to go. Then go to "Software Options", "Test commands" then
