The heat dissipation plate, known as a "heat sink," is primarily a metal "heat dissipation plate" that functions to transfer heat generated within semiconductor devices to the surrounding fluid (gas or liquid) to dissipate that heat. It is also capable of absorbing heat generated inside the semiconductor. Our company has 60 years of experience and has solved various challenges for our customers. We can accommodate micron-level flatness and specified warp processing, as well as resist baked printing. Please feel free to consult with us. 【Features】 ■ High dimensional and hole pitch accuracy due to precision total extraction molds ■ Continuous processing of coil materials up to a thickness of 5mm by adopting progressive molds ■ UV printing adopted ■ Capability for micron-level flatness and specified warp processing ■ Also supports resist baked printing *For more details, please refer to the PDF materials or feel free to contact us.

Our company handles heat sinks (base plates). Thanks to precision progressive dies, the dimensional accuracy of the outer shape and hole pitch has greatly improved, resulting in significantly enhanced finish quality on both the edge and shear surfaces. The coil material can be continuously processed up to a thickness of 5mm due to the adoption of progressive dies, contributing to lower costs and shorter delivery times. We utilize UV printing. In addition to micron-level flatness and specified warp processing, we also support resist baked printing. 【Features】 ■ High dimensional accuracy of the outer shape and hole pitch due to precision progressive dies ■ Continuous processing of coil material up to a thickness of 5mm through the use of progressive dies ■ Adoption of UV printing ■ Capability for micron-level flatness and specified warp processing ■ Support for resist baked printing *For more details, please refer to the PDF document or feel free to contact us.
