Locate "Pin 1" on the 8681L (usually marked by a small dot or notch). Align it with the indicator on the PCB.
Solder one corner pin first to hold the IC in place. Re-verify alignment before soldering the remaining pins.
Check the surface-mount resistors and capacitors surrounding the 8681L, as they often fail alongside the IC.
