Suitable for applications such as power supplies, inverters, and high-current circuit boards and device components!
We would like to introduce our "Functional Step Board." Through our step circuit process, we can arrange high-current circuits using thick copper foil, such as 70μm, and fine wire control circuits using copper foil, such as 18μm, on the same substrate. This allows us to provide copper-thick hybrid circuit boards with continuous wiring. By forming unevenness through step formation in part of the circuit, we can enable height adjustment of mounted components and impart functions based on shape and structure in substrates used for device components. 【Specifications (Partial)】 ■ Base material copper foil thickness: 18μm, 35μm, 70μm, 105μm ■ Maximum step height - 18μm copper foil: 12μm - 35μm copper foil: 25μm - 70μm copper foil: 50μm - 105μm copper foil: 80μm *For more details, please refer to the PDF document or feel free to contact us.
