Through Board Desoldering High Melting Point Solder...

The power wires for a 500 watt ebike motor go through the board. It there any off the shelf insulator designed to protect the caps and other components only 13 mm away? This is asking for a torch.

Two suggestions:

Don\'t start with a torch!
Post a link to a photo (or two) to sci.electronics.repair

It would help to explain the reference to \"High Melting Point Solder\". 500 watts
isn\'t a lot of power. Normal solder and 12 AWG wire is sufficient under most
circumstances to carry it. An old Weller WTCP with a blunt 800 degree tip can
handle that sort of job. It has to be used quickly, the board material will
degrade fast.

Try Chip Quik. It\'s a bismuth alloy that should make the high-melting
solder lower-melting.
