5.Little knowledge --- What is the difference between a copper substrate and an aluminum substrate?
Copper substrate
Copper substrate is one of the most expensive in the substrate metal, thermal effect is better than aluminum base plate and the iron base board are a lot of times, suitable for high frequency circuit and the change of high and low temperature of large area and precise communication equipment heat dissipation and architectural decoration industry.
Generally, there are gold copper substrate, silver-plated copper base plate, tin copper substrate, copper oxide substrate and so on.


The copper substrate circuit layer requires a large capacity of current-carrying capacity, which should be used in thick copper foil with a thickness of 35 mm ~280 mm.Thermal insulation layer is copper substrate core technology, the core component of thermal conductivity for 3 oxidation 2 aluminium and silicon powder and epoxy resin filled polymer composition, thermal resistance is small (0.15), viscoelastic can good, has the ability of thermal aging, able to withstand mechanical and thermal stress.Copper substrate metal base is copper substrate support components, requires high heat conductivity, usually copper, also can use copper (copper plate can provide better thermal conductivity), suitable for drilling, punching and shearing and cutting and other conventional mechanical processing.

Aluminum plate
Aluminum substrate is made of aluminum substrate, because of its strong heat dissipation ability, such boards are commonly found in LED lighting products.There are two sides, the white side is the welding LED pin, the other side presents the aluminum, and the general will be applied to the heat of the heat in the heat transfer part of the contact.
The aluminum substrate is a kind of metal clad copper plate with good heat dissipation function, and the general single panel consists of three layers, namely the circuit layer (copper foil), the insulating layer and the metal base.For high-end use, there are also two panels, which are circuit layer, insulating layer, aluminum base, insulating layer and circuit layer.Very few applications are multilayer boards, which can be made from ordinary multilayer boards with insulation layer and aluminum substrate.
