worked on boards that needed repair. I am not sure how I feel about the blowtorch method (I do think hot air has merit). Who out there thinks that a blowtorch used in this manner produces less thermal shock on the ICs than a desoldering gun working pin-by-pin?
I ammend my answer as I've never used a blow torch. I can see that method being problemmatic as you most likely wouldn't have the fine control a proper soldering iron would bring. A properly tipped heat gun would even be better. I have seen something in between a blow torch and what Bruce describes. the torch heats the iron from the inside. It's meant for field work where there is no power. Most of the blow torches I've used would have burnt a hole through the board and anything behind it (yes, it was meant for metal cutting). -- Linux Home Automation Neil Cherry ncherry@linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies
