The aluminum substrate pcb most commonly used in printed circuit boards is a glass fiber reinforced (fiberglass) epoxy resin with a copper foil bonded on to one or both sides. PCBs made from paper reinforced phenolic resin with a bonded copper foil are less expensive and are often used in household electrical devices.Then do you know which material is used in PCB?Next, Yongmingsheng, a professional aluminum substrate pcb manufacturer, will tell you in detail.
The general single panel consists of three layers of structure, namely the circuit layer (copper foil), the insulation layer and therefore the metal base.The purpose of aluminium pcb led in parallel series is to form the aluminum substrate recover cooling , like 1WLED aluminum substrate already belongs to the high power.
There’s a cooling pad at rock bottom , the warmth dissipation pad is additionally covered with copper, and therefore the positive and negative wires are often narrowed accordingly, in order that the warmth dissipation are going to be better.Aluminum substrate is usually utilized in power devices, power density is high, therefore the copper foil is comparatively thick.
The aluminium pcb manufacturing process:Tin-sprayed aluminum substrate, aluminum substrate, silver-plated aluminum substrate, gold-immersed aluminum substrate, etc.
Electrical functionality is predicated on PCB function for aluminium backed pcb, which makes it an honest criterion for design-based circuit card material selection. consistent with function, PCBs could also be classified because the following board types: High Frequency (High Speed) – These boards can accommodate frequencies within the 500MHz – 2GHz range.
The above is the use of aluminum substrate materials and technology, I hope to have a certain help to you.We are the supplier of aluminum substrate from China – Yongmingsheng, welcome to consult!
