Hi to all...
On Ebay i've buyed a little ultrasonic bath. I wont to say what liquid i need to use for wash the flux and clean PCBs... In past i've used trelin with a paint-brush, but it's not the max with plastic parts... I've tried wth denaturated alcohol and water/ammonia, but nothing... Thanks!!!! |

Isopropyl alcohol works a lot better than denatured alcohol on rosin.
You can buy the 91% stuff in supermarkets if you look around, but the 70% often has glycerin and fragrances added; I'd stay away from that. Acetone is also good for electronics (provided none of the components are soluble in it!) but a major fire/fume hazard. Make sure you've got good ventilation if you're going to mess with that. |

Enrico- Take care that you don't damage circuit boards with your ultrasonic bath. Such a bath works best on hard objects and may damage soft materials like plastics or fiberglass circuit boards. It will create holes in aluminum foil. It would clean a watch band or eye glasses with glass lenses using soapy water, but might damage plastic lenses. For removing flux, I found a product called "water remover and fuel system antifreeze" that contains almost pure Isopropyl Alcohol. Sometimes you can find 98% Isopropyl Alcohol at a drug store. The 70% rubbing alcohol doesn't work very well, since it contains a lot of water. I use an "acid brush" to apply it to the circuit boards. It might be a good idea to use hearing protection around the ultrasonic bath. Even though you can't hear it, it has an effect on you. Fred |
