Product Description

Pcb design led single-side DOB aluminium pcb circuit board 7W 40mm 9W Led


Aluminum PCB(metal base PCB board: contains aluminum pcb,copper pcb,iron pcb) is a unique metal-based copper clad laminate,it has good thermal conductivity,electrical insulation and machining performance.
Aluminium PCB is one of metal-based pcb,including copper foil,thermal insulating layer and metal substrate,its structure divide into three layers:
1. Circuit layer: the equivalent of an ordinary PCB,copper thickness from 1oz to 10oz.

2. Insulation layer: Insulation is a layer of thermal insulating material with low thermal resistance.Thickness: 0.003 “to 0.006” inch is the aluminum pcb core technology.
3. Based Layer: a metal substrate,usually aluminum or copper may be chosen.
●  Use of surface mount technology (SMT);
●  The circuit design of the thermal diffusion of highly effective treatment;
●  Reduce product operating temperature,increase the power density and reliability,extended product life;
●  Smaller footprint,lower hardware and assembly costs;
●  Replace the fragile ceramic base pcb,better mechanical durability.
As an advocate to promote energy-saving lamps and colorful energy-saving LED lights are very popular by the market, the aluminum pcb used in LED lights have begun a large-scale applications.
