[Processing Example] Etching Process for Power Devices

[Processing Example] Etching Process for Power Devices

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.

[Processing Example] Etching Process - Metal Foreign Matter (Contamination)

[Processing Example] Etching Process - Metal Foreign Matter (Contamination)

With fine etching processing, it is possible to reproduce metal foreign substances (contaminants) in arbitrary shapes!

Hirai Precision Industries' etching process uses a film or glass plate known as a master plate for processing. Therefore, even if the requested size of the design drawn on the plate is a small shape, it is possible to carry out the processing. Taking advantage of that feature, there are also requests to intentionally create metal foreign objects (contaminants). This serves the purpose of evaluating the removal of foreign objects that may occur during manufacturing. [Case Overview] ■ Product Shape: Individual numbers from 0 to 9 ■ Material: SUS304-CSP-H ■ Plate Thickness: 0.01t ■ Minimum Residual Width: 0.05mm ■ Minimum Cutting Width: 0.05mm ■ Comparison Object: 0.5mm wide mechanical pencil lead *For more details, please refer to the PDF document or feel free to contact us.

[Processing Example] Etching Processing, Black Dyeing, Black Treatment

[Processing Example] Etching Processing, Black Dyeing, Black Treatment

Produced while suppressing warping and distortion in the finish! Depending on your request, partial black dyeing can also be accommodated.

Etched products are used as light shields (aperture plates) for built-in camera modules in smartphones and mobile phones. To absorb light, they are generally black in appearance. There are also specifications that stack multiple plates to allow for fine adjustments of hole sizes. The holes are usually circular, but can also be of irregular shapes. However, with Hirai Precision Industry's etching process, it is possible to easily create irregular shapes. **Advantages of creating apertures through etching:** - Compared to machining (laser processing, wire electrical discharge machining, cutting), etching can produce parts with reduced warping and distortion. - It can process thin foils with a thickness of 0.005mm. - Not only etching, but also black surface treatment can be processed and delivered consistently. *For more details, please refer to the PDF document or feel free to contact us.*
