| Semiconductor encapsulating mold cleaning sheet |
 |
| Mold cleaning sheets made of rubber with excellent workability and cleaning ability. |
|
Outline |
|
| Continuous ordinary resin transfer molding requires washing of the molding dies because of oxidation of the encapsulating agent with molding dies resulting deterioration in demolding. Nitto Denko mold cleaning sheet made of non-vulcanized rubber is vulcanized when pressurized, bonds with the stains, and recovers releasability of the molding dies. |
