Well first off I wouldn't evaluate paste for a wave process. I would use solder bar instead. Flux - top side fillets and no shorting on the solder side, does it clean well after processing if using water soluble flux. How wide is the process win

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.

use water soluble solder paste is the cure for your problem. but if you insist of using NC change your pogo pins to pointed pins.

Use Water soluble if you can, if not I would try the Indium SMQ NC paste, this residue stays soft. I would also change ICT probes to the "drill type". Russ

When you say "clean solder paste", do you mean not "no clean"? "clean solder paste" is not a common term and I for one do not understand what you mean by it. I believe you mean "water soluble" Commonly there is "no clean" and "water soluble". The

Why not a water soluble paste? They have very active flux. Russ

Sn62Pb36Ag2 has a higher liquidus point of 189C as compared to Sn63Pb37 at 183C. You may need to slightly adjust your oven profiles to use it compared to SnPb. We have had good solder-ability and reliability with it in our IPC Class II products. A

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

Hi, I could like to find out what are the things need to look out if I'm doing a new SMT solder paste ( water soluble & no-clean ) evaluation. And also flux ( spray type ) for wave-solder ( water soluble & no-clean ). Appreciate for all the input..

Time to get more solder paste and have no clearer ideas on the matter than last time. Going through the smaller jars on Digikey these two stand out (as I think they did last time!): One's Water Soluble (that's the one I got last time) and the other
