This time around I'm seeking your input! I've desoldered a few things from time to time, but I've found desoldering IC's to be fairly hit & miss and I'm after your advice on how to do this better - what works for you and what doesn't. I think I've reached an initial conclusion that hot air works best if you're removing a chip and don't care if it gets cooked (ie, saving the board is more important), and that applying fresh solder and using the desoldering gun if best if saving the chip is important, albeit with increased risk to the board. Am I on the right track? === Stuff I use: Digital Microscope: Andonstar AD407 Multimeters: UNI-T UT61E Fluke 75 Dick Smith Q1535 (quite old) Digitech QM1517 (small/toy) Oscilloscope: Rigol DS1052E Other test equipment: Multi-function tester TC1 Tauntek Logic IC tester Minipro TL-866ii UNI-T UTG962 function/arbitrary waveform generator UNI-T UT612 LCR meter Kenwood CG-935P PAL test pattern generator Tools: Haako FR-301 desoldering gun Quick 957DW heat gun Weller EC2002D/EC1201 soldering iron Jaycar QM3546 desk mount adjustable magnifying lamp 3D printer: Flashforge Creator Pro --- Web-site at https://www.tassiebob.com File archive at http://files.tassiebob.com Amazon wishlist at https://www.amazon.com.au/hz/wishlist/ls/2SUJNBDP895I ... https://www.youtube.com/watch?v=BpgwmMC7RB4
