PRODUCTION NOTES
1. Use three 8832 screws to align and attach the heatsinks to the board.
2. When assembling heatsinks to Q20(A&B),Q21(A&B),Q37,
ensure heatsinks are straight and sit flat against board. Add a very small
amount of RTV between heatsink and board if necessary. This prevent
heatsink from shorting other components.
3. Add grease under middle tier mosfets.
