Re: 1502 HV problem
There is supposed to be a Russian substitute for the 20mA diode. My notes show it as 1i308e/Gi308e but I have never been able to find one. The 10mA one can be replaced with a AI201V, which isn't hard

Re: [OT] Best glue to repair lifted trace?
I have tried CA glue on a lifted pad.? It stuck at first but failed immediately when barely touched with a soldering iron.? In your case the continuity is already there and you might risk not

Re: [OT] Best glue to repair lifted trace?
I think you made up your mind. Don't breath the fumes when you solder near ca, or get them in your eyes.

Re: 1502 HV problem
Harvey, I need to visit you one day, before the sales you go to, so I can find me some of these DEALS! It's fun to, it is like a "BOX OF CHOCOLATES, you never know what you gonna get".

Re: 1502 HV problem
Highly fortunate. That's one that nobody has ever found a replacement for. My 1502 is sitting on the shelf with its input protector firmly in place. I was lucky enough to mange to find all of the

Re: Calibration and full checkout needed - Tek 7000 series
Ballpark you can get without special equipment. DMM calibration is something else, but there are 10 volt very accurate references available. It's when you star looking at 4 1/2 digits and up where

Re: [OT] Best glue to repair lifted trace?
IPC 7711/7721 specifies two part epoxy or dry film epoxy for the repair of lifted pads. It costs a lot for a copy but if you do a search, you can find some older versions on the web. This web site

Re: [OT] Best glue to repair lifted trace?
Thanks for the ideas. Tge trackbis just lifted, there is no break. It's flexible, held together by the conformal coating, and there's continuity. So, I want to glue it down. I don't think it would be

This is what I use. It is actually a pcb over coat epoxy but it seems to stand up well to heat. https://www.digikey.com/product-detail/en/chemtronics/CW2500/CW2500-ND/1929217

Re: [OT] Best glue to repair lifted trace?
I'm with Stefan. I have always used epoxy for this. If I'm quick with the soldering iron the trace almost always stays put. I have done the external wire thing as well, with epoxy over the top when

Re: [OT] Best glue to repair lifted trace?
Epoxy would be much better. Probably still won't survive direct soldering (most fast cure epoxy glues don't have the same heat resistance as PCB material), but it will anchor the connector better than
