Bake your solder mask and then solder coat. If you are going to put an immersion finish like Osp, gold, tin or silver you would have to do a Micro etch to clean the copper prior to placing the surface finish. Regards, Board House

If you have a glob of epoxy on your board, it will be difficult to stencil you paste on that side. Dispensing paste may be a better choice.

Does anyone know what an "Axis Head 1 Theta DAC limit error during Move Absolute Command" may mean? It occurred during production. I have checked through the board's program for errors but cannot see any.

I have tried this product and one from Kester with mixed results. Just follow the directions exactly. If it says rub the leads with the swab for 60 seconds, do it! Good luck!

Have someone you know but the sales guy doesn't know you know, ask for the same part with no lead. I would not be suprised if the sales guy sang a different tune then. Stephen

Hi, I am an engineer based in Scotland, but have some IC's sitting with a company in the Boston area, that need checked for coplanarity. Does anybody know of a company/ lab with a lead inspection machine that they could be sent to? Regards, Dave.
