Hi, I am planning to go get a TEK 7904 in the next couple of days, and I just wanted to know the methods of cleaning the PCBs of such high-performance scopes.
I cracked this guy open at the recycling center and there was mud everywhere inside. I mean dirt from the earth; lots of dust too. It was very likely rained on and maybe under an evergreen tree from the number of sticks and thin leaves inside. I hope to restore this scope.
I know that some people use soapy water to clean PCBs of lower-end devices, but this scope is specified at 500MHz, and I just wanted to know other "proper" methods.
IPA baths? Use only air and toothbrush? Use copper(II)chloride to dissolve all aluminum to clean the vias? (joke)
Thanks
