TYPE 2

1. Place unpopulated PCB on heat-sink.
2. Use ink to mark the lead positions on the heat-sink.
3. Place transistors on heat sink with the pins bent straight up
4. Align the transistors leads with the ink marks
5. Use ink to mark the mounting holes of each transistor
6. Drill mounting holes
7. Mount transistors
8. Populate PCB
