PCB aluminum substrate, also known as aluminum based circuit board, is a metal based copper clad plate with good thermal conductivity, electrical insulation performance, and mechanical processing performance.
Aluminum substrate is a metal based copper clad plate with good heat dissipation function. Generally, a single panel consists of a three-layer structure, namely a circuit layer (copper foil), an insulation layer, and a metal substrate. Some designs for high-end use are also double-sided boards, with a structure of circuit layer, insulation layer, aluminum base, insulation layer, and circuit layer. Very few applications are multilayer boards, which can be made by bonding ordinary multilayer boards with insulation layers and aluminum substrates. After the circuit is arranged through software, the path and holes can be processed by printing, etching, mechanical processing, etc., which can be used for users to assemble electronic parts for testing. Provide precision PCB circuit board manufacturing services, adopt advanced manufacturing equipment and continuously develop multi-layer PCB circuit board manufacturing technology to manufacture high-quality single sided, double-sided, and multi-layer PCBs. In addition, our flexible production lines and manufacturing capabilities can provide customers with a large and small amount of manufacturing services, while achieving price and delivery time goals
PCB also means printed circuit board, but the material of the circuit board is aluminum alloy. Previously, our general circuit board material was fiberglass. However, due to the high heat generated by LEDs, the circuit board used for LED lighting fixtures is usually aluminum substrate. The commonly used PCB aluminum substrate material is metal based copper clad plate (mainly aluminum based and copper based, with a few being iron based).
Metal aluminum based copper clad plate is a plate-like material made by immersing electronic fiberglass cloth or other reinforcing materials in resin, single resin, etc. as insulation bonding layer, and covering one or both sides with copper foil and hot pressing. It is mainly used for processing and manufacturing PCB aluminum substrates, and is widely used in products such as televisions, radio receivers, computers, computers, mobile communication, LED lighting, etc.
Introduction to PCB aluminum substrate materials
As the substrate material in the manufacturing of PCB aluminum substrate, metal aluminum based copper clad plate mainly plays the role of interconnection, conduction, insulation and support for the PCB aluminum substrate, and has a great impact on the signal transmission speed, energy loss and characteristic impedance in the circuit.
The performance, quality, processability, manufacturing level, manufacturing cost, and long-term reliability and stability of PCB aluminum substrate largely depend on the metal aluminum based copper clad plate.
