The difference and application between aluminum substrate and glass fiber board
PCB, that is, printed circuit board, is the general term of commonly used circuit board, which can be divided into cardboard, semi-fiberglass board, fiberglass board, metal substrate, etc.
1, fiberglass board (FR4, single-sided, double-sided, multi-layer PCB circuit board, impedance board, blind hole board), suitable for computer, mobile phone and other electronic and digital products.
There are many names for fiberglass board. Let's take a look first; FR-4 also known as fiberglass board; Fiberglass board; FR4 stiffening plate; FR-4 epoxy resin plate; Flame retardant insulation board; Epoxy plate, FR4 light slide plate; Epoxy glass cloth plate; Circuit board drilling floor is generally used for flexible packaging base, and then wrapped with cloth, leather, etc., to make beautiful wall, ceiling decoration. It is widely used. It has the characteristics of sound absorption, sound insulation, heat insulation, environmental protection and flame retardant.
Fiberglass board is a composite material made of epoxy resin, filler and glass fiber.
The main technical characteristics and applications of FR4 light plate: stable electrical insulation, good flatness, smooth surface, no pits, excessive thickness tolerance, suitable for high performance electronic insulation products, Such as FPC reinforcement board, tin furnace high temperature resistant board, carbon film, precision star wheel, PCB test rack, electrical (electrical) equipment insulation partition, insulation plate, transformer insulation parts, motor insulation parts, deflection coil terminal board, electronic switch insulation board.
Because of its good material properties, fiberglass board is widely used in traditional electrical, electronic and digital products. The price is higher than paper and half glass fiber, the specific price varies according to the product requirements. Fiberglass board is also widely used in digital electronics.
Because of its special advantages, fiberglass board has been widely used in electronic manufacturing enterprises. Fiberglass board can be assembled in a variety of ways, such as V-slot, punch hole, bridge, etc.
2, aluminum substrate (single-sided aluminum substrate, double-sided aluminum substrate), aluminum substrate mainly has excellent heat dissipation performance, suitable for LED technology. The base is made of aluminum.
Aluminum substrate is a kind of metal - clad copper laminate with good heat dissipation. Generally speaking, a panel consists of three layers, namely the circuit layer (copper foil), the insulation layer and the metal base. For high-end use, there are circuit layer, insulation layer, aluminum base, insulation layer, circuit layer double panel design. Very few applications are multilaminates, which can be made from ordinary multilaminates, insulating layers, and aluminum bases.
Aluminum substrate is a kind of PCB. Aluminum substrate is a metal - based printed board with high thermal conductivity. Generally used for solar energy, LED lamps and other products that need heat dissipation, but the circuit board material is aluminum alloy. In the past, our general circuit board material is glass fiber. However, due to the heat of LED, the circuit board of LED lamps is generally aluminum substrate, which can conduct heat quickly.
