I've a query. I have one new Customer whom insisted us to use RMA paste on their product. The problem is, on some of their products they use via hole as the test point in where all the PCB finished are ENTEK and as usual I have to print solder paste

| hello to everybody, | we have a really satisfactory no clean process, both smt/reflow and wave soldering, but we get troubles with defects rework; | does anybody know how to eliminate flux residues or how not to produce them during rework operatio

There are chemistries out there that will solublize some post-solder NC flux residues. I have had success with Zestron material Vigon A200 and Petroferm material Hydrex DX. Go to http://www.zestron.com and http://www.petroferm.com These are chemical

Michael, You're right, of course. A major mis-type on my end. What I meant to say is that no-clean fluxes are designed to not _require_ cleaning to meet industry cleanliness standards. Cheers ..rob

We'd suggest listening to your CSP component supplier. The standoff is too low. Check with your flux suppliers for the information you seek.

By definition, no clean solder can be not-cleaned. The solder/flux are formulated to result in low ionic-contamination, hence, no cleaning. I have, however, always had at least one customer that requests their no-clean solder get cleaned. No-clean

You are comparing apples to oranges. No-clean fluxes, because they are designed not to be cleaned off after reflow, contain very low solids. Normally, no-cleans have a solids content of 2% - 5%. Your basic RMA has a solids content of 15% to 30% (s

aight... Ive read the SMT archives... Ive got issues,,, 25 boards WS boards with NC on them HOw do I clean them? Used Everkleen in Prewash and wash in a dishwasher , cleaned most of the NC flux off but I have residuals. especially on the fine pitch

Hi Rob, I must take issue with your statement �By definition, no clean solder can be not-cleaned�. All no-clean fluxes can be cleaned. Whether or not one cleans no-clean depends on a variety of factors. More than eighty percent of all post reflow
