Default Re: Desoldering help

Or if you have a soldering tweezers would also work but you would have to add some more solder to the mounting tabs and pins

Or remove the solder from the pins and add more solder to the tabs and remove the part when the solder has melted and is flowing

Which ever method you decide to do you will have to use more heat maybe as high as 800*F make sure your tweezers are up to temperature before you start

If you use a temperature controlled hot air gun turn up the heat and turn down the air flow but do not turn the air flow to low and do it from the back of the part too the edges of the board and keep moving around the part until it comes loose from the board
