Plastic Molding

Achieve a hollow package that meets your requirements and functions with PLAPACS®

Our in-house design allows us to flexibly meet the needs of our customers.

Resin design: We offer the optimal resin for the product through the in-house design.

Product design: We realize the design of products with high efficiency and high quality in cooperation with the in-house design of molding dies.

Production equipment: We are in-house developing efficient dedicated equipment.

PLAPACS® is a plastic cavity package suitable for CCD/CMOS image sensors and other sensors. PLAPACS® has high dimensional precision and high humidity resistance by our unique epoxy resin compound and technology for composite metal and material.

  • High dimensional precision
  • High humidity resistance
  • Low cost
  • Lightweight

・High dimensional precision & Lightweight

Using our resin-design and transfer-molding technology, we achieve drastically accurate dimensions.

・High Humidity Resistance of PLAPACS®

By our unique epoxy resin combination, PLAPACS® resin has a higher moisture absorbency than general semiconductor resin and is impermeable to water.
Accordingly, you can use the package without dew condensation in the cavity even after certain moisture soak.
