Rogers offers liquid cooling materials designed to dissipate large amounts of heat, and provide thermal management of high-power laser diodes and other heat-generating optical devices. The cooling structures are copper foil channels bonded into a tight block, with aluminum-nitride (AlN) isolation layers added for extra performance.
The role of the substrate in power electronics is to provide the interconnections to form an electric circuit (like a printed circuit board), and to cool the components. Compared to materials and techniques used in lower power microelectronics , these substrates must carry higher currents and provide a higher voltage isolation (up to several ...
It is called "soft" because it uses elastomeric materials, most notably PDMS. Soft lithography is generally used to construct features measured on the micrometer to nanometer scale. According to Rogers and Nuzzo (2005), development of soft lithography expanded rapidly from 1995 to 2005. Soft lithography tools are now commercially available.
FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing). "FR" stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless testing is performed to UL 94, Vertical Flame testing in Section 8 at a compliant lab. The ...
Substrate is a term used in materials science and engineering to describe the base material on which processing is conducted. Surfaces have different uses, including producing new film or layers of material and being a base to which another substance is bonded.
Polytetrafluoroethylene (PTFE), better known by its trade name Teflon, has many desirable properties which make it an attractive material for numerous industries. It has good chemical resistance, a low dielectric constant, low dielectric loss, and a low coefficient of friction, making it ideal for reactor linings, circuit boards, and kitchen utensils, to name a few applications.
Joann. The 81-year-old fabric and craft retailer filed for bankruptcy in March, falling victim to customers cutting back on spending, including on fabric, arts and supplies materials. Joann’s ...
John A. Rogers (born August 24, 1967) is an American physical chemist and a materials scientist. He is currently the Louis Simpson and Kimberly Querrey Professor of Materials Science and Engineering, Biomedical Engineering, and Neurological Surgery at Northwestern University .
