PCB single side aluminum substrate

Aluminum substrate is a kind of metal based copper clad laminate with good heat dissipation function. Generally, PCB single side aluminum substrate is composed of three layers, namely circuit layer (copper foil), insulation layer and metal substrate. For high-end use, there are also double-sided boards designed with circuit layer, insulating layer, aluminum base, insulating layer and circuit layer. Very few applications are multilayer boards, which can be made of common multilayer boards, insulating layer and aluminum substrate.
   
Aluminum substrate is a special metal based copper clad laminate, which is widely used because of its good thermal conductivity, heat dissipation, electrical insulation and machining performance. Aluminum substrate is widely used in LED, air conditioner, automobile, oven, electronics, street lamp, high power and so on. Why can aluminum substrate be widely used and used in high-tech products. The thermal expansion, dimensional stability, heat dissipation and other properties of aluminum substrate make it meet more high requirements of products
 
Led single-sided aluminum substrate is one of the classification of aluminum substrate products. Led single-sided aluminum substrate is generally used on LED lamps. The single-sided aluminum substrate only has a layer of copper foil line, and one side is pasted with lamp beads. After the test is OK, it is put into the lamp shell to form a finished product. Led single-sided aluminum substrate is usually used in household lighting, urban lighting, road signs, street lighting, aviation, railway, automobile and new medical fields.
