Hi George, I would suggest you to re-look your process parameters, especially for the pre-heat temperatures and the amount of flux deposited. The mask properties and that of your flux also play a role, but you could zero down to the root cause after

The answer for us at my previous employer was water soluble flux. Wash the board, no residue. If you're not set up to wash (needing a washer, DI water source, waste treatment, ventilation, etc.) it can be expensive and space consuming. Do some resea

Grant, No-Clean paste + IPA = White Residue! #1: Stop using IPA #2: Switch to either a solvent-based de-fluxing chemical or an aqueous-based de-fluxing chemical. If you are using an ultrasonic cleaner for your boards as stated, do not use sapon

I use Simple Green, works pretty well, although I use the concentrate and don't dilute it as is recommended, so it's pretty strong. I am going to try the sugar water though. I'm intrigued.

We're currently using no-clean flux (SR-12) in a no-clean manual soldering process. The brownish flux residue impedes direct visual inspection of the solder joints. Therefore, we're forced to clean the residue off. (1) Is there testing we can do

Russ We agree with your comments on plugging from one side only. But... We believe that it IS possible to trap process chemicals [technically, not flux] in a blind [or any other] via. This can be done by plating the via closed, rather than pluggi

Hi,my master How to iron out such soldering bridge with below conditions: 1.The component(Harness)lead pitch is 2.0mm,the lead length is 3.2mm. 2.PCB width is 1.6mm.Pad size is 1.65mm.Its a single copper PCB 3.using spraying fluxer and no-clean fl

Mohammed, The first suggested place to start with your question would probably be with your flux Mfr. Push them! The quantity of dross is effected by several factors: The higher your solder pot temp., the higher your dross level... but don't go too
