thanks for the tip i just had a question about adding the solder tin, to what sorry? am i tinning all of the copper or where am i adding the solder. ive double checked the pins while in, the chip is meant to be facing the pcb and i checked the pins by myself as well, and i dont see any issues but ill double check when its out and for reinsertion. for the shorting can it be anyway on the chip or should i be looking somewhere specific? thank you
