Cleaning Sheet for Semiconductor Encapsulation Molding Die N-CS Series

Major Application

mold die cleaning and coditioning

About the product

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

  • N-CS series can reduce the time to clean-up molding die.
  • N-CS provides good solution for burrs on surface of molding die, stains from gas and blocking of air vent.
  • As N-CS series are environment safety materials, there is less noxious fumes, contamination and corrosion of molding die after cleaning.

N-CS W type -High filling performance for small-sized cavity-

  • N-CS W type completely fills cavity of mold die without air gap.
  • N-CS W type is suitable for molding die with small cavity for small-sized semiconductor, diodes and mini transistor.
  • N-CS W type is designed in a way that cavity is not blocked when the sheet is set on the mold die at any position.
  • With N-CS W type, the air inside cavity can completely escape to outside and can remove off stains from the entire cavity.
