+81-44-221-2375The inquiry about this product


vs. Liquid Coating

Excellent Process Efficiency and Easy Handling

Elimination of irregular printing and bubbles which are generated by the liquid resin coating process
Good environmental conditions by eliminating solvent evaporation
Efficient production attained by simultaneous processing on both side of the substrate
No warps even in case of thin boards

vs. Resin-Coated Copper Foil (RCC)

Excellent Fine-Pattern Formation

Easy etching process in the panel plating method because of the free control of the conductivity-body thickness.
No need of extra process such as copper foil removal in the semi-additive process。

Efficient Laser Processing

The process to remove the copper foil from the spot prior to CO2 laser application, which is needed in case of RCC, is not necessary

vs. Photo-Via Materials

High Degrees of Freedom in Designing

Via formation between not only 1-2 layers but 1-3 layers is possible in case plural insulation layers are built up
