From: Chris on 2 Feb 2010 19:10 I have a tuning fork can sealed with solder. Similar to a sealed crystal can. My 200W soldering gun doesn't even seem to have enough BTU's to melt very much of the solder on the can. Any suggestions? It is a rather large heat sink capacity. Regards, Chris Maness

I can take the shield plates off PC boards with a very small Metcal tip. 200 Watts is about 4 times the power of the Metcal. Is that a Weller gun? Are all the terminals tight? Clean? Tinned? G²

I searched for "tuning fork can" and only found sentences like "a tuning fork can help you tune a piano". Do you plan to use the can again after you open it. I've seen tuning forks in velvet-lined boxes. Or wrapped in felt in any old box. Is a can that important? If the can is round, doesn't it waste space? >Similar to a sealed >crystal can.

A roofer's soldering iron? If it's too hot, might it not damage the fork or ignite the other packaging? >It is a rather large heat sink capacity. > >Regards, >Chris Maness

It has a driver coil on one side and a exciter coil on the other. It also has a divide by two flip flop inside, this probably has a bad transistor because it is not dividing by two anymore.
