"Location of SMC on logic board" için yanıtIf you think the fault is the SMC chip, you can try to re-flow first and see if that would work. Put 2-3 drops of Kester 186 between logic board and SMC chip. Pre-heat the board to 110-120C and gradually heat the SMC chip to 245C. Use thermocouple on top of chip to measure the temp. Put a desktop computer screw on top of thermocouple to avoid being hit directly by the heat. If you have a digital USB microscope you can watch when the solder balls will melt
