Abstract

High thermally conductive cuboid aluminum nitride block was used as reinforcement material to fill the FR4 matrix for the fabrication of a novel FR4/AlN PCB (Printed Circuit Board) with high thermal conductivity. This novel PCB was subjected to a thermal shock test of 1500 cycles from -40°C keeping 30 minutes to 125°C keeping 30 minutes during 1000 hours with transfer time less than 10 seconds, presented an excellent reliability since there was no crack and delamination emerging. By performing a comparative study between FR4/AlN PCB and anodized MCPCB, it was found that the thermal resistance of both PCB were 0.63°C /W and 2.74°C /W respectively. When CREE XTE LEDs were mounted on FR4/AlN PCB and anodized MCPCB using SMT technology to dissipate heat respectively, the LEDs’ junction temperature were 37°C and 42.1°C and the overall corresponding thermal resistance were 3.93°C /W and 6.43°C /W accordingly. Therefore, a conclusion can be drawn that this novel PCB exhibits a more excellent heat dissipation performance than 30W/m·K anodized MCPCB does and it is a promising alternative of MCPCB for heat dissipation of high power electronic devices like LEDs.
