You've told us nothing about your situation, process, boards, or anything!!! If you leave some boards with very fine solder connections on the shelf for a cuppla years, the grain will become coarse. What do you mean when you say "grainy"? What is

Of course recognize off the top that I have a certain bias :-) - and the choices are somewhat limited if you are looking for off-the-shelf product. There is also NO independent agency that I know of (i.e. an electronic training "Consumers Report")

Consider using a roll solder with a flux that well matches the residues you can accept to be remaining on the board when you get finished processing. Many people use a no-clean flux cored roll solder for such operations, because they don't want to c

You should specify the level of res based on the effect of the res on the end-use of the product. J-STD-001 defines cleanliness requirements for ALL flux types, including water soluble and no-clean that you mention. 1 There is no equivalency betwee

Hi!Charlie, 1.Are you retrofitting your spray fluxer in your wave soldering machine? If you are, please ensure that you have a air knife just before the preheater!Fluxe fumes tends to accumulate and that could be dangerous if your air exhaust is not

Thanks, gentlemen. All points well taken, and some hit pretty close to home. Our pick-and-place programmer assures me that coplanarity isn't the issue because the machine won't (or can't) place parts beyond an acceptable criteria. It's an Amistar
