Hi!
I bought one of the cheap and popular Morion MV89A OCXOs off eBay. Unfortunately, it came still attached to a chunk of PCB. I just tried unsoldering the sucker but didn't quite get there. I used my Weller soldering station so I guess that shouldn't be the problem.
I did get most of the solder off by using a good ol' sucker but there's still enough in there to keep the OCXO firmly attached to the PCB. I also tried solder wick but that didn't do anything at all - maybe mine is rubbish.
So - any tips how to get this thing off? My next idea would have been to heat the whole PCB with a hot air rework tool that I can access at my local hackerspace and try to lift off the PCB once all the solder has liquified. But if there's a gentler way using just a soldering iron I would be very interested in reading about it
Ahh, the MV89A, cool devices for the price.
Ideally you would use one of these heated desolder devices with a tip with a hole going through it and a pump attached (de-soldering irons?), they work quite well, maybe your hackerspace has one. Big ground planes and stuff could still be a problem.
For a MV89A using hot air should work, these take quite a bit of abuse. I have actually opened one with a propane torch to replace a broken capacitor, still works after soldering it shut again. Not so good for drift specs I guess though.
The pins on these are quite rugged, you might get away with heating a pin, pulling it out a bit (in effect bending the PCB a little bit), letting it cool, doing the next pin, and so on. Would take a while I guess.
