For plain old QFPs in small quantities, a temperature controlled heat gun + a decent soldering station can do the trick. In my case, Steinel HL 2010 E heat gun (handheld, but with a digital readout) to desolder. Clean up pads with solder wick. Solder

If this is a one time rework might I suggest farming it out? 100pin QFP can be taken off no problemo.. Putting it back down properly and then hand soldering??? I wouldn't want that job. You need excellent placement and imaging and your not going to

It all depends on the quantity and the type of product / quality requirements. Manual placement for 20 mil pitch is not _that_ hard. Another advantage of hand soldering is that you don't have to worry about the moisture level of the replacement par

Hello Ok there is not much info here. What you have to mae sure of is several key factors. 1. Have you entered the correct stencil thickness. 2. Are you using the stencil gerber (not the paste layer) The paste layer is usually not adjusted for ap
