-. Mount the guide pins the bottom heatsink.
• Clean all polished contact surfaces
carefully with Ethanol. Then wipe the surface
in order get very thin layer oil.
Place the semiconductor the right direction. Check the semiconductor's symbol and type
specification.
• void contact with surface. Connect the gate cables.
The contact surfaces must dry before
lubrication. Smooth the
oil lightly over the whole surface using
lint-free paper.

• Drip couple drops silicone oil on
the cleaned contact surfaces, avoid
getting oil the guide hole.

• Use well moistened lint-free paper.
• Lightly polish the contact surface f
semiconductor (the nickel layer must not
be polished through) with abrasive cloth
P600 which fix flat surface.
• Lubricate directly after
polishing/cleaning, within minutes. Preparation heat sink and semiconductor.
