Thanks Dave, I actually found that article yesterday. It is one of the better ones out there. Unfortunately, though Ed does concede that there is a "sweet spot" in the process window for trying to reflow 01005's with SAC305 using air, no further inf

The criterion you use will depend on the test method you select. For minimum requirements, look at J-STD-001C, Para 8, "Cleanliness Requirements". I figure that you�d measure the residues on a lot of your current product, measure the res on a lot o

Steve What do you mean by better? More/less activity? fewer retouches? longer shelf life at ambient temperature? less hygroscopicity? longer open time on the stencil? easier to wash? easier to treat waste water? easier for washing machine maintenanc
