Then wipe the surface
in order get very thin layer oil.
13.
• Lubricate directly after
polishing/cleaning, within minutes. Smooth the
oil lightly over the whole surface using
lint-free paper.
• Clean all polished contact surfaces
carefully with Ethanol. Preparation heat sink and semiconductor.
Place the semiconductor the right direction.
The contact surfaces must dry before
lubrication.
11. Rem ove the faulty thyristors.
• void contact with the surfaces after
lubrication. Mount the guide pins the bottom heatsink.
12. Connect the gate cables.
• Drip couple drops silicone oil on
the cleaned contact surfaces, avoid
getting oil the guide hole.
• void contact with surface.

• Use well moistened lint-free paper. Check the semiconductor's symbol and type
specification.10.
• Lightly polish the contact surface f
semiconductor (the nickel layer must not
be polished through) with abrasive cloth
P600 which fix flat surface
