Reflow -> Wash ? And is there any difference among Leaded / Lead-Free, Water-soluble / No-clean and One-side / Top&Bottom ? If there are any correlations with Wash-process, please send me those information too. Also, if I can get same information f

Steve, Water-soluble fluxes are per definition very corrosive and need to be cleaned (read the data sheet) Encapsulation will prevent humidity reaching the water-soluble acids but will not prevent reducing the metals the flux is in contact with to m

OA: as in Organic Activated type of Solder paste, meaning the flux vehicle is an organic type. which is actually a water-soluble type. this is the opposite of a NoClean type.

We need to use water-soluble paste due to cleanliness requirements. No-clean does not mean No-contamination. I have talked to a lot of people who use no-clean and they still wash their boards except now they have to use chemicals to do it. So, you

Most metal stencils today are cleaned with a water based cleaning solution. 3 choices are most typical: (1) Water only for water-soluble paste (2) Water + Organic for rosin and no-clean (low residues. This affords lower temperatures and is easier t

Good Afternoon, I know that most of the answers I get for this are going to be along the lines of "it's up to you" and I realize that. But, I was wondering what the most common type of profile that is used in your shop and why? Is it the older "S

Paste Flux / Reflow: Our experiments indicated that the combination of no-clean solder paste and air forced convection reflow produced the fewest tombstone defects, followed by water-soluble paste reflowed in air, and most tombstones occurring with

Dave, Not sure if I understand the question. We do not process No-Clean in our facility at the current time. We are a completely Water-Soluble with a 12 year old Hollis Polyclean In-Line washer. I need to scrap the piece of ****. That's another
