PSL2 Assembly guide
23. Single heatsink assembly
Place a drop of thermal compound on the heatsink front face, the volume of a grain of rice. The back face
can be identified by the countersunk hole.
Next place the mica insulator.
Place a second drop of thermal compound on the mica insulator.
Insert the M3x10 countersunk screw from the back, the LM350 regulator and the Insulating shoulder
washer.
Place the M3 nut and tighten all together.
Use your digital multimeter in the Ohm position to check that there is no connection between the
heatsink and the center pin of the regulator.
24. Dual heatsink assembly
Repeat the same operations for the two regulators of the dual heatsink.
