3M Electronics has announced its advanced laminate, embedded capacitor material is RoHS compliant. This material helps OEMs and PCB fabricators meet design requirements for space-constrained applications such as portable and military products.

The 3M embedded capacitance material can be made with a dielectric thickness as thin as 8?m and a capacitance density of more than 10nF per square inch, which makes it among the thinnest and highest capacitance density materials available for embedding planar capacitance in circuit boards, according to the company.

The laminate material allows designers and manufacturers of high-speed digital PCBs to achieve higher speeds while simplifying design trade-offs. When used as "power" and "ground" layers in a multilayer PC-boards, this material becomes a shared decoupling capacitor inside the board, which eliminates the need for many discrete surface-mount capacitors and their associated vias.

In addition, the laminate material also increases useable board area, enables faster signaling, lowers radiated emissions, and saves engineering time associated with power distribution design and board layout, said the company.

PCB fabricators can use the material in military, automated test equipment, computer and telecommunications applications. The material is compatible with all rigid and flex PC-board processing including laser drilling. This material can be used without purchasing a license from 3M.
