300 C is way above the melting point of even RoHS compliant solder, if
you temperature cycled a standard PCB to that temperature, "wrinkles"

feh. You're right. That's the ambient temp just for that cabinet. With the clamp
sinking the heat etc., the temp was actually closer to 200, maybe 250 on a good
day. Only got above 300 when the exhaust fans stopped working, then the boards
would brown real nice and the traces would fall off.
