Answer to: About Thermal Pads and usage of Heatgun?The heat gun will certainly do chap heat your entire board for aprox 1 min then switch to higher setting and heat each chip for about 15 secs before moving on to the next chip even do the small black chips keep rotating remembering which chips in order so all get equal heat , do this process for roughly 4 mins . Heat gun should be about an inch off the board . And your done reassemble and your away. Have done at least 20 machines this way and it has always worked 1st time.(remember to keep away from any plastic areas on the board the best you can.
