PCB ultrasonic baths - GSM-Forum

Hi i have just bought one of these but it had no instructions with it. What do i use to clean PCB's? Can i use white spirit? And also how many times can i use the same liquid? Is it ok to reuse it? Thanks for your advice

I also have the same question.. which chemical is best to use with Ultra Sonic cleaner..

Best Regards,
Wahab

I have done lots of experiments with ultrasonic cleaning machine, and i found out that the best results are using iso-propanol.
Plain alcohol is good, but be sure to use 96% or 98% solution. Medical alcohol contains too much water!
If water is used, it must be destilled.

Iso propanol is not readily available here in the UK and even Alcohol is hard to get hold of, (apart from in a pint glass) any UK users here to advise?

white spirits works fine with them m8

Cheers m8, so is it ok to reuse it until it gets dirty? Did you get the dual sim back that i returned?

You cannot go to drug store and buy alcohol (ethyl alcohol, etanol)? Even if you are legal age? What a strange county

Well you may be able to from certain ones but i think it would only be in tiny amounts. Thanks for the reply m8

HCFC is good,,

willy

johny3310 · 03-16-2003, 22:56

Willy, what is HCFC?

MobileSoft · 03-16-2003, 23:56

I tried pure as well as 90% alcohol, I also tried Methylated Spirits, and 50/50 Distilled Water/Thinners Solution. All these were listed in the manual that came with mines.... but for some strange reason, whenever I use any of the above, All the parts on the phone that need cleaning, turn into white gooey reserdue! Any help? btw Willy, as J3310 asks: What is HCFC?

100% meths worked for me, but you have to dry it well, i used my rework station to do it

i agree that here in uk it will be expensive to wash it with any sort of alcohol...i used water with some soap in it....but im sure this wasnt the problem with the phones...some people may know it

and im sure it wasnt the best idea...i cleaned all my phones just to be sure...and some of them worked afterwoods...some never since...but they were dead anyway...i dont know anyone who actually got his phone fixed by doing this...how important is it? or in which cases u have to use this machine to fix your phone?

johny3310 · 03-17-2003, 08:32
