Aluminum PCB Sheet V FR-4 Glass Fiber Circuit Board
PCB entry sheet is also called printed circuit board. Aluminum PCB sheet and FR-4 glass fiber circuit board are both PCB sheet. The aluminum PCB sheet is to print the circuit on the aluminum base plane with good thermal conductivity, and then solder the electronic components on it.
Compared with FR-4 glass fiber circuit board, the thermal conductivity of aluminum drilling entry board is much better. Because the good heat dissipation of the aluminum sheet is suitable for the requirements of many high-power electrical appliances, most of the aluminum substrates are currently used in the production of LED lighting fixtures.
FR-4 glass fiber circuit board is a traditional electronic product circuit board. Due to its good insulation, corrosion resistance, pressure resistance, multi-layer printing and other characteristics, it is widely used in communications, automotive, medical, industrial control, security and other fields. Most of the LED display screens are of FR-4 glass fiber circuit board.
The key factors influencing the quality of aluminium entry board for PCB drill include aluminum alloy, hardness, surface and thickness. The appropriate size should be selected according to the heat value of the product.
At present, three kinds of circuit boards are used in the field of lighting: FPC circuit boards for the production of led flexible light bars; glass fiber boards are used for ordinary lighting products; and aluminum PCB sheet are mostly used for lighting products.
