We recently changed to an Amtech no clean paste and flux that is washable. So far excellent results. Far superior to the water soluable paste we were using. Fewer solder balls, longer life in printer, boards can be left up to 5 days and still come

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: I'm looking for input from anyone who has experience assembling the MLP package on PCBs. We are experiencing solder opens after assembly, and I'm curious to see how others are processing these critters. The part we are using is a Semtech SH3000

Excess low residue flux is very dangerous to leave on your finished assembly, because it can: * Be corrosive to your solder connections * Promote dendrite growth. To prevent this, follow your supplier's recommendations on: * Applying the proper amou

Russ, We can not use a wave pallet, already went that route. We have parts next to the thru-hole pins and between thru-hole pins. I am going to try an experiment in the next day or so with solder mask. I plan to solder SMT parts on the back of se

Vinesh: The white residue is perfectly expected, when washing a no-clean with water (and some alcohol). In some cases, the white resin that you are seeing can be removed. Your paste supplier should be able to provide details. Recognize that clean

I ran into the same problem. What I had is a customer that required us to use a No Clean because of the Low flux activity then they want it cleaned. Well to clean the No clean your going to use such a high percentage of cleaner in your sapinifer th
