Power transistors
•
Apply a drop of heat conductive compound on the heat sink (see fig 8.0.)
•
Mount the isolation mica onto the heat sink, check the position of the hole.
Apply a drop of heat conductive compound on the mica.
•
Carefully bend the leads, see fig. 9.0
•
Mount the transistor on the heat sink, using a bolt, washer, lock washer
