Rob: Wouldn't that only apply to IR ovens. If using a true convection oven the color of the material wouldn't hinder output at all "Right". Don�t want to see someone spend money on new tooling if unnecessary.

Hello Danial, Leave it up to most to blame the relow oven for their tombstoning problems when in fact it is usually the last to cause it. The biggest culprit of tombstoning is the pad design followed by the print quality. Usually, we find that the p

I use BioAct SC-10 and it seems to work pretty well. The best bet is to contact your solder paste manufacturer and ask them for a recommended cleaning solvent for the flux residues... Regards, Justin

What kind of quality improvements could be expected by implementing MPM's Rheopump instead of using squeegee blades on a stencil printer?

We use a universal recipe for 90% of our products. But, I had to develop a temperature profile for each PCB to know that I was getting the correct temperature at the PCB. You may need to work a weekend or a couple of late nights to get the data. Go

Are you exposing so you can solder and SMD component directly to it? If not are there ant vias near by that connect to the area you are trying to expose? If not I have done as Dave suggested using a dremal tool. Messy but it works.

OEM Boy, Reflow depends on your paste type also. Are you using lead free or will you be going to lead free soon? If your are going to you might want to consider developing two different profiles for lead free and leaded pastes. Good Luck! J.D.
