Special note for assembly
a. The surface of a high voltage silicon diode must be kept clean. The interface between a high voltage silicon diode and the remolding resin must ensure sufficient adhesion.
b. No air bubble is allowed in the remolding, resin because it degrades the insulation and reliability. It must not exist especially near the high voltage silicon diode.
c.The resin material for remolding should be epoxy-base resin and minimum stress from expansion or contraction shall be generated as so to prevent bad influence on the diode .If any resin other than epoxy-base one is used, the adhesion and airtightness to prevent moisture entrance shall be well examined.
