1. Bend leads on hand placed parts in direction of pad and cut short to less than length of pad.
No exceptions unless approved by Production Engineering.
2. Any clinch parts with longer leads than the length of the pad must be cut shorter either prior to
wave-soldering or afterwards in PCB finishing. No exceptions unless approved by Production Engineering.
3. After Wave apply RTV to all holes indicated and all larger and between tall capacitors.
4. Before tightening screw 8832 on xstr spring 4249 ensure that it is aligned with Q4.
Also silpad 4124 should overhang the edge of the heatsink. See picture below.
