M1124 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 prevents the heatsink from shorting other components.
3. There are no eyelets or tabs on this board, so there will
be no mechanical drawing.
4. No RTV under 5watt resistors or relays. Bend leads straight no reliefs.
5. PCBSA: Break out board before testing.
