). There have been a few posts about this but it was never something conclusive. In short -- every time I do some soldering work (recapping is the worst), the PCB looks like a mess. It's sticky, with stains after the soldering pasta, just terrible really. To this day I haven't found out anything better than the ear swabs + IPA. But frankly, I hate it so much:
- it doesn't scale well for big PCBs
- it leaves traces of the wool, especially around through hole soldered components
- it requires several iterations
- it is never perfect!
I've seen those (mostly) Chinese ultrasound cleaners, ones which could accommodate Falcon PCB cost >1000 EUR but several people told me that this is not a good idea for PCB with SMD soldered, like the Falcon is. I have been told that ones which would be good for PCBs like Falcon have price tags with one more zero.So is there a way out?
but for large scale cleanups I tend to use IPA in a small spray bottle and an ESD safe plastic brush to remove flux like this.
