[time-nuts] 5MHz ocxo- Opening Solder sealed cans

[Tom Miller]

Pick up a few sticks of ChipQuik and mix it in with a good iron. Then, you 
may do just what you say. It should melt below about 95°C.
A good hot air heat gun would most likely do the trick. Maybe use some 
solder wick first to lower the amount of tin/lead solder. Then add the 
chipquik.

You might also just solder a tab on the bottom then you could clamp the top 
in a leather jawed vise. Hit it with a hot air gun while pulling on the base 
tab.

I'm somewhat tempted to try putting the bottom in the vice, heating the
whole seam with a hot air gun and trying to pull the case off (with a
heavy leather glove on one hand).

We're having what we laughably call summer in the UK - it's not hot in
any absolute sense (mid-high 20's Celsius) but the humidity after
several week's rain makes it *feel* as though I just have to get the
case a few degrees above ambient and the solder will melt with ease :-)
