Hitachi Chemical Develops Ultrathin, Flexible Multi-Layer PWB Base Material


Tokyo - Hitachi Chemical Co., Ltd. (TSE: 4217) has developed a new base material for multi-layer printed wiring boards. The new base material, named "Cute," is flexible and extremely thin (50 microns or thinner).

Cute is manufactured by applying the company's epoxy-based, low elastic modulus thermosetting resin to coat and impregnate 20-micron or thinner glass cloth and then overlaying it with copper foil.

The company hope the new product will play toward efforts to further miniaturize and slim down portable digital products such as digital camcorders, camera phones, etc.

Hitachi Chemical hope to begin successive commercial production of halogen-free Cute and highly heat-resistant Cute within this year, both of which are designed to be environmentally friendly materials.

The company intends to actively promote the marketing of the new material by focusing on the multi-layer PWB market for portable digital products, and hopes to achieve annual sales of 4 billion yen by FY 2008
