In addition to printed resist, we are implementing innovations using the photo-etching process!
We are performing etching processing on materials that consist of 1.0mm thick copper (Cu) bonded with glass epoxy resin from one side. Hirai Precision Industry has a track record of processing up to 2.0mm thick copper. While copper (Cu) is the mainstream material, aluminum (AL) is also possible. For the insulating layer, we have experience with materials other than glass epoxy resin, including ceramics (aluminum nitride substrates, silicon nitride substrates, etc.), polyimide, and PET film. We often receive materials supplied by customers for etching processing. 【About Etching Processing】 - In addition to printed resist, we employ a photo-etching process for improvements. - This allows for finer finishes and enhanced linearity. - The dimensions of the tapered section of the cross-section can be kept to less than half the thickness of the plate. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Etching Processing + α Possibilities】 ■ It is possible to remove adhesives (filler materials) used for bonding with the insulating layer. ■ We have a track record of prototype support. ・ Plating (electroless plating) processing necessary for assembly. ・ Processing to roughen the copper surface aimed at achieving an anchor effect. ・ Dicing (cutting) the insulating layer, etc. ■ From the etching method applied from one side, it is possible to create steps in a copper plate shape. * For more details, please refer to the PDF document or feel free to contact us.
