N-CS Series

N-CS series is a sheet type cleaning material which removes stains from the molding die used for semiconductor encapsulation. With higher cleaning performance, it can reduce the time to clean-up molding die, compared with conventional cleaning compounds.

Features

Reduced time to clean molding die.
Good solution for: burrs on the surface of the molding die, stains from gas, and blocking of air vent.
Environmentally safe materials, there are less noxious fumes, contamination and corrosion of molding die after cleaning.

How To Use

Image of How to Use

(1) Put the sheet on the molding die.
(2) Compress and mold.
(3) Open the die and remove the sheet.

N-CS W for Small Cavities

Completely fills the cavity of the mold die without an air gap.
Suitable for molding die with small cavity for small-sized semiconductor, diodes and mini transistor.
Designed in a way that the cavity is not blocked when the sheet is set on the mold die in any position.
The air inside the cavity can completely escape from it and can remove off stains from the entire cavity.
