• void contact with surface. Connect the gate cables.
Place the semiconductor the right direction.
• Drip couple drops silicone oil on
the cleaned contact surfaces, avoid
getting oil the guide hole. Check the semiconductor's symbol and type
specification.
11. Then wipe the surface
in order get very thin layer oil.
• Use well moistened lint-free paper.
• void contact with the surfaces after
lubrication.
• Lubricate directly after
polishing/cleaning, within minutes.

-. Preparation heat sink and semiconductor. Smooth the
oil lightly over the whole surface using
lint-free paper. Mount the guide pins the bottom heatsink.
• Clean all polished contact surfaces
carefully with Ethanol.
• Lightly polish the contact surface f
semiconductor (the nickel layer must not
be polished through) with abrasive cloth
P600 which fix flat surface.
The contact surfaces must dry before
lubrication. Rem ove the faulty thyristors
