Let's narrow this down. Questions are: * Are you putting the proper amount of solder in the board with your stencil print process? * If you are putting the proper amount of solder in the board, where is the solder going? Pick one and then fill-in th

S The tater/potater/potatoe is optional, although I'd rather put mine in the microwave while doing the pot swap so I can eat it afterwards.

Be sure to peel the potatoes. I saw a guy use a potato to purify gold on the TV show Rough Science. Seriously though I would think SAC305 to SN100C wouldn't be as bad as eutectic to leadfree.

A water soluble solder paste (AIM WS483), reflow and wash. We are considering using AIM NC254 No-clean solder paste to eliminate the wash step.

We built tens of thousands of boards with transeivers on them with a no clean process.Never had any problems with the flux residue in relationship to board performance.
