Aluminium IMS PCB substrates

Aluminium backed PCBs are now being used in place of traditional FR4 PCBs for high power LED applications. This is due to rapidly changing developments in LED technology, with brighter more powerful LED’s coming on to the market. This raised a problem to designers with larger amounts of heat being generated by the components, the answer came along on the form of IMS (Insulated Metal Substrate) PCB’s. Aluminium backed PCB’s with the use of thermally conductive pre-preg between the copper and the aluminium the thermal performance is 8–10 times better than a standard epoxy glass (FR4) PCB. We are able to manufacture single sided, PTH or multilayer Aluminium backed PCB’s to your requirements.

tec-thermal IMS Series: aluminum base layer; ceramic filled, non-reinforced dielectric

Versatile choice of formable substrates, selective dielectric and conductivity from 2.2 W/mK to 10 W/mK

Ventec’s IMS (Insulated Metal Substrate) families, laminates and prepregs for multilayer PCBs, leverage innovative formulas for excellent thermal performance. Selective-preference VT-4B5SP extend choice and design freedom even further.

As a world leader in thermal management solutions, Laird Technologies offers the Tlam™ thermally-conductive PCB substrate system. Tlam™ thermally-conductive PCB substrates provide 8-10 times the heat dissipation compared to conventional FR4-based PCBs. The miniaturation of electronic devices continues to pack more and more power into smaller and smaller packages. The simplicity of the Tlam™ system takes the heat dissipation requirement in stride without significant design changes. The Tlam™ dielectrics are the key to these high-performance PCB substrates. The Tlam™ dielectric provides electrical isolation, thermal transfer, and adhesion layer for the substrates that are created for your specific needs.

Denka company logo. The word Denka, in a bold dark blue font.

A highly thermally conductive insulated metal substrate (IMS) consisting of an aluminum base, an epoxy-based insulation layer with a high inorganic content filler demonstrating high thermal conductivity, and a conductive foil, thereby realizing thermal resistance equivalent to, or less than that of an alumina ceramic substrate.
