MOLD CLEANING RUBBER SHEET

Mold cleaning process was a mandatory process for Semiconductor to clean away the epoxy deposits formed during the molding process for Integrated Circuit, Diodes, transistor etc. Cleaning method includes the Melamine Based Cleaner and Rubber Base mold cleaner. End users shall apply different combination of cleaning methology depend on cost factors, internal requirement, customers requirement as well as productivity aspect. Rubber Sheet cleaner is a fast cure material compare to Melamine base cleaner. It does not need any lead frame and preheating for performing the cleaning process. With the elimination of preheating and shorter cure time, customer can gain productivity improvement with Rubber Base Cleaner. This will also prolong the mold tool life since this rubber sheet don’t require higher pressure (clamping pressure) and unlike melamine/compression type that causing some problem such as mismatch and offset on the product specially for insert type cavity and guide pin due to excessive melamine compound inserted during mold cleaning causing cavity and guide pin to have slight movement overtime.

RUBBER SHEET

Specially formulated compound for the cleaning of thermosetting transfer mold. It has its excellent elastic properties which easing the removal of the compound from the mold without leaving any unwanted debris and assist in the house keeping of the molding station. Besides , it was also formulated with high  flow characteristic to achieve cleaning efficiency. It emits limited odor during the cleaning process.

ADVANTAGES & BENEFITS

  • Air vents, cavities and mold surfaces  cleaning & conditioning in single  step.
  • Cost saving in total cleaning  materials.
  • Shorter cleaning time & productivity gain.
  • Cater for green compound  requirements.
  • Environmental friendly, using non  hazardous ingredients and Halogen  Free.
  • No preheat, no thawing time is needed.
  • Suitable for semiconductor,  optoelectronics, rubber, plastic and  metal molding industries.
ELASTOWET

Specially formulated compound for wetting and conditioning of thermosetting transfer mold after mold cleaning. Elastowet has good compatibility with Rubclean. It also has excellent elastic properties to ease the removal of cured rubber after molding.It also has high flow characteristic to ensure rubber wax flow into all cavities to achieve waxing homogenous during the conditioning process.

APPLICATION PROCEDURES

  • Locate Elastowet on mold for the required number of strips. 1 to 2 Elastowet strips per mold chase depending on the frame and mold cavities dimensions.
  • Clamp the mold to compress Elastowet to fully fill up all the mold cavities. Over clamping the compound may cause releasing difficulty from mold.
  • Suggested compound cure time is depending on mold temperature. For normal molding temperature of 175 +/- 5 °C, the compound cure time required can be from 180 to 240 seconds.
  • Number of conditioning shots suggested is 1 to 2 shots after mold cleaning.
  • Over curing Elastowet (more than 10 mins for 180 °C) might create sticking problem to the mold.

  • “KWC”

Specially formulated compound for wetting and conditioning of  thermosetting transfer mold after mold cleaning. KWC has  good compatibility with Rubclean. It also has excellent elastic  properties to ease the removal of cured rubber after molding. It  also has high flow characteristic to ensure rubber wax flow into  all cavities to achieve waxing homogenous during the  conditioning process.

APPLICATION PROCEDURES

  • Locate KWC on mold for the  required number of strips. 1 to 2  KWC strips per mold chase  depending on the frame and mold  cavities dimensions.
  • Clamp the mold to compress  KWC to fully fill up all the mold  cavities. Over clamping the compound may cause releasing difficulty from  mold.
  • Suggested compound cure time is  depending on mold temparature. For  normal molding temperature of 175 +/- 5 °C, the compound cure time required can be from 180 to 240  seconds.
  • Number of conditioning shots suggested is  1 to 2 shots after mold cleaning.
  • Over curing KWC (more than 10 mins for 180 °C) might create sticking  problem to the  mold.
