Semiconductor Chip Carrier can be divided into thermo-electric modules, and the power electronic substrates.
Thermo-electric modules are plate-like semiconductor cooling devices that work by using the movement of heat when a current flows through the junction of two different metals. Compact, lightweight, and Freon-free, they are used in climate control seats of automobiles, cooling chillers, optical communications, biotechnology, air conditionners, dryers and a variety of consumer electronic products.
Application of Thermo-electric module Manufacturing Technology for Heat Dissipation and Insulation Substrate
Generally, organic and metal substrates are used in the circuit boards of low-power home appliances and computers.
In particular, silicon nitride substrates are attracting attention for use in power modules of inverters and converters because of the increase in sales of HEVs and EVs.

Construction
ACSR/TW, a non-homogenous conductor, is a trapezoidal shaped wire compact concentriclay- stranded conductor made from aluminum 1350-H19 (extra hard) wires and round, coated steel core wire(s). Several
combinations of aluminum and steel strands and layers are possible to design ACSR/TW conductors with equal area or equal diameter as compared to ACSR conductors for overhead lines. Commonly used sizes are included here. Class A zinc coating (ACSR/TW/GA2) is usually adequate for ordinary environments to protect the steel core wires from corrosion.
ACSR/TW conductors are manufactured in accordance with the ASTM specification B779. Other ASTM referenced specifications include B230, B498, B500, B 606, B802, B803, B957 and B958.
Features
The favorable strength/weight ratio, from the light weight and good conductivity of aluminum with the high tensile strength of steel, makes ACSR conductors a preferred choice for overhead power transmission and distribution projects. Steel strands provide mechanical reinforcement to handle higher line tensions, reduce sag, and longer span lengths. ACSR conductors are recognized for their dependable performance under adverse weather conditions. Use of ACSR/TW with the equal area design allows equal ampacity in a conductor with approximately 10% smaller diameter over a standard ACSR with same area. This smaller diameter of equal area ACSR/ TW conductors helps reduce the
effects of ice and wind loading on the conductor. Use of ACSR/TW with equal diameter design provides
a conductor in which the aluminum area is increased by approximately 20% - 25% over a standard ACSR with same diameter. This increase in the cross-sectional area of the conductor reduces its ac
resistance by about 15% - 20% and thus, increases its current carrying capacity by about 10%.
