Semiconductor Encapsulating Mold Cleaning Sheet

Mold cleaning sheets made of rubber with excellent workability and cleaning ability.

Outline

Continuous ordinary resin transfer molding rires 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.

Features

• Can be used immediately on the same molding condition in use without presettingand offers excellent workability.
• Need no supplemental material such as dummy lead frames as in the case of other cleaning materials (melamine resin); just place the rubber sheet into the molding die.
• Superior cleaning function is manifested in excellent removability of contaminants.
