Contributing to the heat dissipation of power semiconductors (power devices)! "Etching process"

Suppressing heat generation of power semiconductors used in electric vehicles (EVs) and smartphones! Efficiently dissipating heat with a "heat sink" using etching processing.

Power semiconductors (power devices) are semiconductors capable of handling large currents and high voltages, and they are being developed for a wide range of applications, including electric vehicles and smartphones. Our company mainly collaborates on the processing of lead frames that support and fix power semiconductor (power device) chips and connect wiring, as well as heat sinks, and we often assist with tools and metal masks used in production processes. We can process complex and intricate shapes without using molds, achieving precision at the micron level (3μm to 2mm) in a short time. 【Features】 - Complex parts can be manufactured with micron-level processing accuracy in a short time without molds. - In lead frames, we have a variety of materials, including pure copper and copper alloys, and we can perform etching processing. - For heat sinks, we can handle thick copper with precision machining (fiber laser processing and wire electrical discharge machining) from Hirai Precision Industry. *For more details, please refer to the PDF document or feel free to contact us.
