What are other DIY’ers doing for board cleaning? No-clean flux and forget it? Rosin-core and IPA? Ultrasonic baths?
My practice in the past has been to use 99% IPA, a tupperware tray for soaking, and an old toothbrush, but I recently switched to this Sparkfun lead-free solder with a water-soluble flux.
IPA doesn’t do a very good job on this, and I finally tracked down the manufacturer recommendations on the flux, which is to water-wash without cleaning agents:
I’m going to try doing the same tupperware/toothbrush strategy that I used with IPA, plus drying with compressed air and/or a heatgun. But I see people online using ultrasonic cleaners, special PCB spraying equipment, even dishwashers(!!) Anyone have good anecdotes?
