Metal core or IMS (Insulated Metallic Substrate) circuit boards are an excellent alternative to standard circuit boards, if the circuit boards are exposed to large mechanical loads, or a high level of dimensional stability is required, or high temperatures must be conducted away from power components or LED's.
The thermal conductivity assisted by the aluminium cores in the circuit boards makes higher packing densities, longer operating times, and improved security against failure possible, such as for LED technology and for high power transistors.
Additional application areas for this technology include: high current application, power LED's, SMD and power circuit boards. The high thermal conductivity permits a quick and effective transfer of the heat produced.
Available types
You can order single sided and double sided pth aluminium core circuit boards from Multi CB (see: layer build-up). Depending on the design, thermal conductivity ranges from 0.67 to 2.2 W/m*K! (The value for FR4 is approx. 0.3 W/m*K.)
