We are using our selective solder machine to solder a backplane with sixteen (16) 4x48 pin 0.080" connectors. Our first pass yield is about 85% meaning that 85% of the connectors come out with no bridges. Not quite as fine pitch as your connector a

J-STD-001C requires removal of gold from (through-hole) component leads when the thickness of the gold layer is above 2.5 microns to prevent problems with embrittlement. The thickness of gold on an ENIG board typically is around 0.05 micron, resultin

Use a Radial lead inserter. you will need 1 head for each different part number you have. the machine cannsert 2.5 $ 5.o mm lead components and 7.5 with special to0ling. For LED you want to use a Radial with the new dual spocket CTA (Component transf
