Copper coin embedded printed circuit board
Improving thermal conductivity by embedding copper coins! Introducing printed circuit boards that efficiently dissipate heat.
To efficiently utilize the thermal conductivity of copper (390 W/m·K) for heat dissipation, we introduce a printed circuit board embedded with copper coins in the heat-generating area. In conventional methods, heat dissipation vias were arranged as much as possible, but due to the inability to increase the cross-sectional area of copper, there were limitations in heat dissipation. In the developed product, the thermal conductivity has been improved by embedding copper coins. 【Comparison of Conductor Cross-sectional Area】 ■ Through Hole (25μm) - φ3.0mm 1 hole: 0.23 mm² - φ8mm area: 1.41 mm² (φ0.4mm TH, 1.0mm pitch, 48 holes) ■ Copper Coin - φ3.0mm 1 hole: 7.07 mm² (approximately 30 times) - φ8mm area: 50.24 mm² (1 hole of φ8mm copper coin) (approximately 35 times) *For more details, please refer to the PDF document or feel free to contact us.
