Microma 1974: what silver epoxy?

Post13 Dec 2019, 10:56

Recently I was lucky enough to get a donor module with a clear and crisp lcd panel for the chunky Microma 1974 (i have a NOS bought almost 6-7 years ago).
The module seems to be working as it should.
The only problem is related to some missing segments :-( , and the question is quite simple:
1) How gently remove the lcd panel
2) What silver epoxy apply (i think something like a glue or gel is better)...
3) How keeps in place the panel once removed

Best conductive epoxy for a reasonable price...ebay item number 161121885337. Top-of-the-line...MG products, item number 231609627449 (probably too expensive to consider, unless you do a lot of this type of repairs). I use the MG for driver-transistor replacement on P2 and P3 modules. You need a sharp needle, a 15-20X magnifier, and a steady hand, but it does work. I'm not familiar enough with the specific watch to advise you on the mechanical disassembly/assembly.

Thanks for the advice Bruce,
At the moment the watch is fixed with two soft thiknesses on the lcd and after one week is still working fine... i have to clean and lubricate the two recessed buttons :-D

Here the library link (thanks Adam!):
