Hi Rick, Water soluble flux is heatee, deionized water. So, use DI, and keep it heated. It is also important that the water be moving, so that fresh water is continually being presented to the fluxed surfaces, and the flux-laden water is continually

1. Most ionic testing is measured in NaCl, that is, the ionic residues are quantified in terms of NaCl equivalence. The test does not determine what the ionic residue is, just its relative strengh. 2. I use IPC cleanliness specs on OA fluxes but n

Hi all, We have a little discussion here about the suitable flux for a certain process, as all of us are beginners we need your advice. We are producing VGA cards and mother boards for PC's all components to be wave soldered are TH, the SMD is done

| Does anyone have any recommendations on spray fluxers? Are there major differences between the high priced ultrasonic machines to the low priced flux/air spraying machines? We are going to be spraying an OA flux with 11% solids content. Are there a

Sylvia, I believe you will find that contrary to Scott Cooks submission, that the work carried out by Robert Clark of Hughes Missile Systems at (then) Tuscon Arizona formed the basis of the MIL-F-14256 spec which "Qualified?" or at least "Approved" O

WS609 is a wonderful paste. J-STD-001, 4.2 states words to the effect that for Class 3 products Type H or M fluxes should only be used for tinning operatins. Most water soluable fluxes are either H or M. I believe that you can use Type H or M flux

Hi, Distance Engineering is always difficult. I am guessing that the old machine and process ran wonderfully / acceptable. If you still have the old machine, how about running an empty board through it and then the new machine. Without flux observ

Your customer's question is reasonable. Soldering to nickel is not always a walk on the beach [can of corn, or whatever]. This issue is flux not solder. Your Sn63 will have plenty of strength, providing the solder connection is well formed. You s

I recently did a no clean flux eval and by far the leader in the category for remainder (residue) was Interflux 2005MZ 1. You first mission is to provide acceptable solder joints. 2. Only apply what you need to achieve acceptable results. Spray f
