Intensity ripple on Tek 465B

I don't know but I have both indium solder (93C) and that ChipQuik stuff. However, if I can identify one cracked joint, the silver Epoxy should take care of it.

I have no intention of removing the hybrid from the mainboard! Silver Epoxy on those joints as well if need be. :)

So far the cleaning is holding up. Fingers crossed.

Thanks.

OK, I'm assuming you've found a way to heat the air first. I'm interested in this setup - could you elaborate?

In this case, it wasn't a matter of heat. It turned out that simply air flow made the difference since this occurred immediately after power on before anything had a chance to heat up.

If I had to provide heat, a blow dryer would have been my tool of choice :)

Note that your breath will have high levels of moisture in it,that could alter the conductivity of the thick-film elements,especially if the thick- film is dirty.

I used to use an ordinary hairdryer(folding travel style) at low heat,until one of the cleaning people stole it.(along with my TI-30 calculator)

a paper cone narrowed the air flow to what I desired.

Could be part of the effect. Anyhow, it is still stable today.
