| | We are using a mixed technology process with mostly through-hole parts plus some SMT IC's on the component side and some passive SMT parts on the solder side. We do not have a proper wave soldering machine for doing solder side SMT (double wave

Russ: You've got stop soft-peddling this stuff. This doesn't sound like "poor solderability." It sounds like "no solderability." It also sounds like you�re dead meat. Three places to call: 1 Board supplier to get their suggestions on unsolderab

We look at gluing and pasting second side components as two different processes, NOT alternative processes. Given our drothers, we'd paste / place / reflow all day long, before we'd want to glue. We glue because we have to glue. The main driver to

Does anyone have knowledge or experience with Pin & Paste on boards that are .095" thick? The boards would have mixed technology, PTH, fine pitch, and BGAs. I did a search for this info and nothing touches on this particular subject, thicker boards.

Help! We have been doing some trials on Paste Through Hole and have encountered a problem. The screen is designed (as is suggested in technical info re PTH) to give double the paste volume required to fill the void between the pin and via. The pro

All Y'll How do you clean components that must be added to an assembled board after water wash? BACKGROUND Our basic process goes like this: 1 Print paste with OA flux, place, reflow, wash 2 Repeat 1 3 Insert PTH, OA flux, wave, wash 4 Insert
