Just a thought, but have you pulled the datasheet for the part and confirmed that the plating on the leads is compatible with your current process/profile?

Sure. Section 7.4 covers unsupported holes, and defines the usual standards. Clinching, fillet on the plated side, lead protrusion, etc. Cheers, ..rob

This connector was designed with gold flash plating and the lead's surface was become dull and some black mark was observed on the contact surface.

Anyone can help me how many percentage of blowholes and pinholes if i do the followings: 1. Increase copper plating thickness more than 25 microns. 2. Pre Baking of PCB to remove gassing by drying out the PCB's

I was unaware of any Pb-Free process capable FR-1 laminate... not to mention capable of Though Hole plating that would be expected when wave soldering. What is the Td and Z-expansion for the laminate you are using?

Hi, FR1 laminiate used is only for single side type and THD plating is not used. I have also attached laminate manufaturer's datasheet. Thanks,

The manual says to bake the edge chains at 400C to clean them. Is anybody doing this ? I need to take my edge chains to a heat treat facility to clean them ? I don't want to spray oven cleaner on them as they appear to be plated with nickel or so

Is there a directory for North American electroforming houses? My specific need is for large area production (e.g., Fuji 4000 screens, etc.) of 29" x 29" or greater. Any specific recommendations would be gratefully accepted. Photo-plotting capabil

Thanks Mac! I have been doing a lot of reading and I think I understand me challenge ahead of me. I do however have a double sided assembly and the BGA's are on the second side. So I know I have to make this a quick build…. June

Yes, thank you. Found out that machine ran over two parts to tall and damaged the cover plate over the centering.
