Metal Substrates Are Used In A Wide Range Of Applications

Shenzhen Inno Circuit Co.,Ltd | Updated: Aug 17, 2017

Metal substrates are widely used in lighting, medical, consumer electronics, power, communications, aerospace and other fields.

Development of metal substrates and market conditions

Metal substrate development and market conditions With the electronic products to the light, thin, small, high density, multi-functional development, printed circuit board component assembly density and integration is getting higher and higher, power consumption is growing, Metal Base PCB the PCB The substrate heat dissipation requirements more and more urgent, if the substrate heat dissipation is not good, it will lead to printed circuit board components overheating, so that the reliability of the machine down. In this context, a high heat dissipation metal substrate was born. Metal substrate is the most widely used aluminum-based CCL, the product was invented by the Japanese Sanyo National Policy in 1969, 1974 began to be used in STK series power amplifier hybrid integrated circuits. The early 80s China's metal-based CCL is mainly used in military products, when the metal substrate material completely dependent on imports, expensive. Metal Base PCB In the late 1980s, with the aluminum-based CCL in the automotive, motorcycle electronic products in the extensive use and expansion of the amount of China's metal substrate to promote the development of research and manufacturing technology and its electronics, telecommunications, Metal Base PCB power and many other areas widely used.

Metal substrate characteristics and application areas: iron-based CCL and silicon steel CCL has excellent electrical properties, magnetic permeability, pressure, substrate strength. Mainly used for brushless DC motor, tape recorders, included machine with a spindle motor and intelligent drive. Metal Base PCB But the silicon steel CCL is superior to iron-based CCL; copper-based CCL with aluminum-based CCL basic performance, the heat dissipation is better than aluminum-based CCL, the substrate can carry high current for the manufacture of power electronics and Automotive electronics and other high-power circuit with PCB, but the copper substrate density, high value, easy to oxidation, Metal Base PCB so that its application is limited, the amount is much lower than the aluminum-based CCL. Aluminum-based CCL has excellent electrical performance, heat dissipation, electromagnetic shielding, Metal Base PCB high pressure and bending plus q-, can be used mainly for automobiles, motorcycles, computers, home appliances, communications electronics, power electronics products.

Metal substrates in the aluminum-based CCL the largest market, the application examples are as follows. Automotive power supply: power supply regulator, ignition device, voltage regulator, power supply, power supply, power supply, Components: power supply, floppy drive, CPU; power supply; switch regulator, switch, DC-DC converter, regulator, regulator, DC-AC converter, large power supply, solar power supply board; Telephone, Metal Base PCB mobile phone high frequency booster, filter circuit, sending circuit; electronic control: relay, transistor base; switch; radiator, semiconductor device insulation thermal conductivity board, motor controller; other: IC chip carrier, air regulator.

Market development trend of metal substrate With the development of electronic technology, the market demand for aluminum-based CCL is heating up, while the technical requirements for metal PCB substrate is also getting higher and higher, can be summarized as the following aspects: a. Metal Base PCB The higher the thermal conductivity of the metal substrate; b. Aluminum clad laminate is required to withstand higher breakdown voltages, requiring a maximum breakdown voltage of up to 15 kV (DC, AC). The 704 plant has been able to provide pressure resistant to 8 kV (AC) and 10 kV (DC) Copper cladding
