I don't know the name of the flux. but is a no-clean solder paste.

i have the experience like that, it should have something to do with solder paste.

We have been using the Amtech line for over 12 years now with all of our PCB and BGA Rework. The NWS-4400 is mildly active and will give better results with Lead Free Solder. Note that the LF-4300 is considered a No-Clean. However it will show lea

Hi, I wondering if someone know the anwser to that. I'm using a solder paste 63/37 and on the solder joint we have a tiny little layer or flux who is like crystalin. I try to play with my profile the get it off but I don't get much success. So D

If the hand soldering is done right and you use little to no extra flux (other than whats in the solder wire) you should be ok. You should still verify with some testing however... You need to make sure any flux used is activated, thus rendered benig

We use NC flux exclusively for SMT and wave soldering. And it is a fairly old formula from Multicore, though we are currently qualifying a new formula. The automated soldering does not appear to be a problem. It is only the hand soldering that causes

Questions are: * On what portion of the second side of the board [eg, solder only, solder mask only, etc] do you see this white hazy residue? * Could you attach a picture? * You mention cleaning this residue. What have you used to clean the residue?

Hi ! In both solder mask and solder joint, I am going to upload a picture today promise, I use only IPA and a ESD brush this kinda clean the problem

Glenn, i am aware of one unique problem with voc free fluxes. since these fluxes have certain amountb of water content they cause sputtering leading to solder balls & voids problems. Regards Vinesh Gandhi | I require some feed back from any one

I have a customer that is having a flux residue problem after wave soldering. Flux is roaring through the board to the top side and leaving a residue. This is only happening on the flat stamped leads. The round leads are fine. They are using Supe
