Ed, I have opened and repaired several sealed oscillators, OCXOs and TCXOs, as well as crystal filters, with some success. In fact the Isotemp OCXO in my homebrew GPS standard is still going strong after I replaced the TL431 regulator in that ten years ago.
What I do is to use a box cutter type knife on the seams, side by side, repeatedly scraping out as much of the solder as possible. After a while the seam can usually be opened up enough to break any remaining solder towards the corners. I think the fact that this avoids any prolonged heating is probably the main advantage of using this method. It takes time, but so far I have not found one that wouldn't open in the end... Do I have to say: be careful and always work away from your fingers? It works for me at any rate, and by not using heat you avoid any extra damage :^) Dan _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
