Square SMD LED aluminum plate pCB board For LED Light Lamp
Custom Square Smd Aluminum Plate Led Pcb Board For Led Light Lamp
Advantages of Aluminium PCB:
There are various advantages of aluminum PCBs, some of them are,
1. Affordable Metal Core PCB
Aluminum PCBs are much cheaper than other metal core PCBs. They have higher thermal conductivity as compared to commonly used FR-4 PCBs. In contrast, if you use copper or stainless-steel PCBs, then it will be higher in cost. Thus, you can save money by getting the cheapest type of metal core PCBs. The reason behind the low cost is that aluminum is easily available and has a low cost as compared to other metals used for MCPCBs.
2. High Thermal Conductivity
Aluminum is used because of its high thermal conductivity. It can easily dissipate the heat generated by the components on board. It can withstand high temperatures. The dielectric conducts the heat from the components and helps in dissipating the heat. Thus, it protects the components working on the board and can increase life. Moreover, there is no need to use heat sinks. If your PCB needs many heat sinks, then a better option could be aluminum PCB. It could save you money.
3. Shape Retainment
The problem with the FR-4 board is that they cannot retain their shape at high temperatures. The board starts to bend, and it cannot retain its dimensions. On the other hand, the aluminum board can retain the shape under temperature and pressure stress.
4. Environmentally Friendly
Aluminum is environmentally friendly, and there is no harm in using it. It’s according to international standards. It’s 100% non-toxic. It can also be recycled.
5. Durability
Aluminum PCBs are durable. They can withstand wear and tear and extreme temperatures. Aluminum is much stronger than a common FR-4 substrate, and it has a high capability of preventing accidental damages. It can handle more pressure and stress. There is a very low probability of the breakage of the board.
6. Lightweight
Aluminum has a very lightweight as compared to copper and stainless steel. So, the final product can have less weight.
