MAINTENANCE: Safe electronics cleaning tips?
« on: June 24, 2010, 08:52:37 PM »
Hello!  New to robotics and I can see I'm going to have to do a lot of reading up.

First off, however, this may seem like a dumb question but are there any cleaning tips you can give me?

I've ended up with what is supposedly a working CRS A255 arm and had no idea of its real value until I started looking on the internet.  Now that I've seen what they can go for I've become a bit timid about 'cleaning' it up.  I'm sure it doesn't need to be babied but I also don't want to wreck anything through ignorance.

My main concern is with the controller because in whatever configuration it was last used, it seems the housing was removed so that the case is just open and the circuits, etc., are all exposed.  I'm guessing its use was industrial rather than in a lab because it's really not that clean in there.  I've found some general resources for cleaning electronics but are there any specific items that anyone can thing of that I should be aware of?  (also with regard to cleaning cables, etc.)

In fact any setup information would be incredibly helpful.  I'll probably have to move a bit slowly because I've realized I'll have to dig out an old PC from the basement just to use the software.

Thanks in advance for any insight!

for cleaning static sensitive PCBs use compressed air to blow dirt off.
for some reason compressed air produces less static electricity than a vacuum cleaner.

years ago when i used to have a field service job we always used to use a foaming car seat upholstery cleaner for cleaning the outside cases of grubby machines.
the important part is that any residue it leaves when it dries is non conductive incase it slops onto the PCBs.
try buying a can but make sure to test it with your multimeter on high resistance setting.

a cleaner like that would in theory be ok for the inside of a machine as well but i don't think i would risk it.
stick with compressed air on the inside.

Thanks; that's good to know too re: compressed air > vacuum.
