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 ...
The structure on the left is called a hairpin filter and is an example of a band ... (e.g. Rogers Corporation 6010 ... Properties of common substrate materials ...
Consider the structure of the proposed 1-bit unit cell, which operates at 28 GHz. [36] It is based on the design presented in. [ 37 ] It consists of two metal layers, printed on a Rogers RT5880 substrate material having a thickness of 0.254 mm, a dielectric constant of 2.2, and a loss tangent of 0.0009.
Engineering the original surface structure allows us to soften the stiff electronics. Buckling, island connection, and the Kirigami concept have all been employed successfully to make the entire system stretchy. [7] [8] Mechanical buckling can be used to create wavy structures on elastomeric thin substrates.
LSAT substrates are popular for epitaxial oxides and their heterostructures, often in the study of electron correlation phenomena. Typical materials grown on LSAT substrates include strontium titanate (SrTiO 3 ), cuprate superconductors (such as YBCO ), iron-based superconductors (iron-pnictides), rare-earth manganites , rare-earth nickelates ...
Gadolinium Gallium Garnet (GGG, Gd 3 Ga 5 O 12) is a synthetic crystalline material of the garnet group, with good mechanical, thermal, and optical properties. It is typically colorless. It has a cubic lattice, a density of 7.08 g/cm 3 and its Mohs hardness is variously noted as 6.5 and 7.5.
Structure of poly-oxydiphenylene-pyromellitimide Kapton insulating pads for mounting electronic parts on a heat sink. Kapton is a polyimide film used in flexible printed circuits (flexible electronics) and space blankets, which are used on spacecraft, satellites, and various space instruments.
