Product Description

CHEMLINQ WS830 Wax Conditioning Sheets are used to protect the mold surface and ensure a good releasing effect after cleaning. It is a waxing sheet that provides an ideal balance between great mold protection and high workability and it can be used for Green and non Green EMC as well as manual and auto molding processes.

CHEMLINQ WS830 performs well in a wide range of molds and has a curing time of ~ 180-240 seconds. These sheets are highly effective as a protection and release product. They have good flow characteristics which enable them to easily reach into the mold corners and thin gate areas. Used in combination with our RCS Rubber Cleaning Sheets, the short mold waxing and cleaning time will lead to reduced costs and will increase your overall efficiency and productivity.

Product Key Features

  • High Flow — decreases friction, thus making the molding cycle faster and more efficient..
  • Homogenous Waxing — improves lubrication; ensures efficient and even coverage of the mold surface

Applications

  • Improving mold release during semiconductor molding process

Specific Gravity
Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Usage

  • Place 1-2 WS830 strips per mold chase depending on the frame and mold cavity design.
  • Clamp the mold to fully fill up all the mold cavities.
  • Over clamping the compound may cause releasing difficulties from mold.
  • The suggested compound cure time is dependent on mold temperature.
  • For normal molding temperatures of 175 ±5 °C, the cure time ranges from 180 to 240 sec.
  • The number of conditioning shots suggested is 1 to 2 shots after mold cleaning.
  • Curing the product for more than 10 mins for 180 °C might create sticking problems.
