Aluminum pcb vs fr4 pcb board

FR4 board is a code name for the grade of flame-retardant material. It represents a material specification that the resin material must be able to extinguish by itself after burning. It is not a material name, but a material grade. Therefore, there are many types of FR-4 grade materials used for pcb, but most of them are composite materials made of so-called Tera-Function epoxy resin, Filler and glass fiber.

FR-4 PCB board, according to different uses, industry insider generally call them: FR-4 Epoxy Glass Cloth, insulating board, epoxy board, epoxy resin board, brominated epoxy resin board, FR-4 , Fiberglass board, fiberglass board, FR-4 reinforcement board, FPC reinforcement board, flexible circuit board reinforcement board, FR-4 epoxy resin board, flame-retardant insulation board, FR-4 laminated board, epoxy board , FR-4 light board, FR-4 fiberglass board, epoxy glass cloth board, epoxy glass cloth laminate, circuit board drilling pad etc.

Main technical features and applications of FR-4 board: stable electrical insulation performance, good flatness, smooth surface, no pits, thickness tolerance standards, suitable for high-performance electronic insulation requirements products, such as FPC reinforcement board, PCB drilling pad, glass fiber meson, potentiometer carbon film printed glass fiber board, precision star gear (wafer grinding), precision test plate, electrical (electrical) equipment insulation support spacer, insulation backing plate, transformer insulation plate, motor insulation, grinding gear, electronic switch insulation board, etc.

The aluminum pcb board is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single-sided aluminum PCB is composed of a three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base layer. For high-end use, it is also designed as a double-sided board, and the structure is circuit layer, insulating layer, aluminum base, insulating layer, and circuit layer. Very few applications are multi-layer boards, which can be formed by bonding ordinary multi-layer boards with insulating layers and aluminum bases.

Compared with traditional FR-4 PCB, aluminum pcb circuit boards have the following advantages:

1. Good thermal conductivity. The metal layer of the aluminum pcb board can quickly dissipate heat, transfer the heat of the device, minimize the thermal resistance, and have good thermal conductivity.
2. More environmentally friendly. Aluminum-based pcb boards do not contain substances harmful to human health and the environment, and are more environmentally friendly than FR-4 circuit boards.
3. High durability. FR-4 pcb may be warped, bent, cracked etc during production and transportation; ceramic substrates are also more fragile. Aluminum pcb circuit boards make up for the shortcomings of FR-4 boards and ceramic substrates, have longer durability, and avoid board cracks caused by production and transportation.
4. Higher performance. The circuit layer of the aluminum-based PCB board is etched to form the circuit. Compared with the traditional FR-4 pcb board, under the same line width, thickness, etc., the current carried by the aluminum pcb is higher than that of the FR-4 pcb board.
