Metal Coper Aluminium PCB Board Aluminum Printed Circuit Boards Surface Mount
As is known to all, LED Aluminum Board to drive the cooling application the development of the industry, because the LED Aluminum PCB Board heat characteristic, moreover also has high heat dissipation, low thermal resistance, long service life, the advantages of resistance to voltage, with the improved production technology, equipment, product price rationalization, and expand the application field of LED industry.
At present, the product application of LED Aluminum Printed Circuit Board covers the whole lighting application industry, such as commercial lighting, indoor lighting, LED outdoor lighting, etc.As a whole, LED aluminum board will continue to develop at a high speed in the next few years.
Because aluminum has high thermal conductivity and heat dissipation, it can effectively export the internal heat.Aluminum PCB is a unique metal clad copper plate with good thermal conductivity, electrical insulation and mechanical properties.
Features of LED Aluminum PCB:
1. Surface mount technology (SMT);
2. Extremely effective treatment of thermal diffusion in circuit design scheme;
3. Reduce the operating temperature of the product, improve the product power density and reliability, and extend the service life of the product;
4. Reduce the volume of products and reduce hardware and assembly costs;
5. Replace fragile ceramic substrate to obtain better mechanical endurance.
LED Aluminum PCB Structure:
Aluminum – based copper clad plate is a kind of metal circuit board material, composed of copper foil, thermal insulation layer and metal substrate. Its structure is divided into three layers:
Cireuitl.Layer: copper clad with common PCB, with copper foil thickness loz to 10oz.
DielcctricLayer insulation: insulation layer is a layer of low thermal conductive insulation material.
BaseLayer:metal substrate, usually aluminum or optional copper.Aluminum – based copper clad plate and traditional epoxy glass cloth laminate.
