[time-nuts] 5370B Input Board Repair [WAS: 5370B Question / help needed]

[Thomas Allgeier]

Hello Gary,

The adhesive doesn't come off with solvent - I am afraid very careful 
scraping with a pointy scalpel under the microscope was what did it. That's 
what makes me think it is epoxy-based. Touching it with a hot iron also 
doesn't seem to have much effect. Once cured it probably can only be 
mechanically removed. But it is not immensely strong, I guess the metal 
filler means it can be kind of crumbled off bit by bit. Make sure you really 
get all the debris removed as of course it is conductive and would easily 
cause trouble elsewhere.

I hope you get yours going!

Kind regards,
Thomas.

This is very interesting, I have a 5370B that has the same behavior as
yours. I will take the input board out again and give it a good
inspection. BTW, what did you use to clean the adhesive from the pads ?

Thanks
Gary
