Title: Noob-Question: How to "wash" a board
Post by: Tyrem on January 31, 2013, 10:59:44 AM: Heyho again. :)

I must admit... I am ashamed to ask this question but I´ve seen that some people offer to clean pcbs.
I wonder how to do this in the best way since some of my boards would need some cleaning for sure.

Any advice for me from you guys?

Greetings from Trier!
Stefan

'helped'? What do you mean? How should this help?

ah, I understand. I think the only way to get rid of such dirt is to use a very small flat screwdriver and put it in each pin of the sockets. A re-insert of the ICs should also do the job :)

Post by: ARCADESAVER on February 27, 2013, 08:53:49 PM: I use all times my dishwasher, only PCBs what i not put in there, are pcb with a suicide bat like the Gaeleco Rally boards. When u put a a pcb with a bat into a dishwasher u can be sure it not longer work after the wash cycle ;D
I never pull the ic out of the sockets, only 2 weeks drying after the wash cycle, that is important :)

Post by: level42 on March 01, 2013, 07:13:42 PM: So after you washed them you don't do any manual drying ? Just let it stand there for 2 weeks ?
In those 2 weeks the water rests will be happily corroding any metal right ?
