What is aluminum laminate?
Aluminum substrate is a kind of metal-based copper-clad board with good heat dissipation function, generally a single panel consists of three layers of structure, which are circuit layer (copper foil), insulation layer and metal base layer, commonly used in LED lighting products. There are two sides, the white side is soldered LED pins, the other side presents the original color of aluminum, generally will be coated with thermal conduction gel after contact with the thermal conductivity part.
What is a PCB board?
PCB board generally refers to printed circuit boards, PCB circuit boards, also known as printed circuit boards, is the provider of electrical connections for electronic components. Its development has been more than 100 years of history, its design is mainly layout design, the main advantage of using circuit boards is to greatly reduce the wiring and assembly errors, improve the level of automation and production labor rate. We usually say that the printed circuit board refers to the bare board, hiyo ni, no components on the board.
LED aluminum substrate is PCB aluminum sheet, is also the meaning of printed circuit board, but the material of the circuit board is aluminum, before we generally the material of the circuit board is glass fiber, but because the LED heat is larger, so the LED lamps and lanterns with the circuit board is generally aluminum substrate, able to conduct heat quickly, other equipment or electrical class with the circuit board or glass fiber board!
What is the difference between aluminum substrate and pcb board?
pcb board and aluminum substrate in the design are in accordance with the requirements of the pcb board, the current aluminum-based pcb board in the market is generally the case of single-sided aluminum substrate, pcb board is a large variety of aluminum substrate is just a type of pcb board, is an aluminum-based metal plate with good thermal conductivity.
pcb board in general is the copper substrate, which is also divided into a single panel and double panel, the material used between the two is a very obvious difference, the main material of the aluminum substrate is aluminum plate, while the main material of the pcb board is copper. Aluminum substrate because of its special PP material, heat dissipation is better, the price is also more expensive.
Comparison between the two in terms of heat dissipation, aluminum substrate in terms of heat dissipation is more superior to the performance of the pcb board, its thermal conductivity is also different, aluminum substrate is a kind of PCB, aluminum substrate price is more expensive.
