My company is developing a product that will require solder paste to be printed on a piece of cast aluminum. The surface of the casting is not completely flat. It has been recommended that one way to work around this might be to use a screen instea

I would also "nice to have" because of your process. Inspecting solder paste from a 2D point of view manually would not assure you quality if the paste is 75% off pad. Plus hand placing onto solder paste causes it's own set of problems which will c

Outstanding advice gentlemen! To borrow Dave F's line "I'd like to take a bit of a different angle." Ie. a few wave solder specific issues If this assembly is going over wave solder then avoid vias under passive components, it invites solder bal

It's unlikely that anyone other than the biggest of whooses would think of 0.031" a fine pitch. I prefer 0.025" on tape with solder plated copper leads make in a shape that bears-up well after being driven over by a Mack truck, yet is compliant enou
