LED Aluminum PCB Technology of MOKO
Led is a very hot product now, which caused many Led-related industries have also been a different concern and increase the production. As the core of Led products, Led PCB and PCBA is very important. Usually the basic material of Led board is Aluminum, as it has a better thermal conductivity than other materials.
Aluminum Led PCB is composed of circuit layer(copper foil layer), thermal insulation layer and metal core layer. Circuits layer required good curren-carrying capacity, that need use thicker copper foil which from 35um to 280um; Thermal insulation layer is the core technology of aluminum board, it is usually made up of special ceramics and fill special polymers, with small thermal resistance, great viscoelasticity, and has thermal aging ability, also able to withstand mechanical and thermal stress. Thermal insulation layer of IMS-H01, IMS-H02 and Led-0601 and other high performance aluminum PCB are using this technology, which has great thermal conductivity, basically it is aluminum base, can also use copper(copper base can provide better thermal conductivity), suitable for drilling, punching,shearing, cutting and other regular mechanical Processing. Surface finish include:Gold plated,HASL,OSP,Immersion gold,lead-free ROHS process etc.
Aluminum Pcb’s features including: thin insulation layer, low thermal resistance,nonmagnetic, good heat dissipation,high mechanical strength; And for aluminum pcb board, the board thickness is different with normal FR4 material pcb, it has 0.8mm,1.0mm,1.2mm,1.5mm,2.0mm,2.5mm and 3.0mm.Copper foil thickness: 18um,35um,70um,105um,140um;Usage:LED dedicated,power hybrid IC(HIC).
Aluminum PCB is the carrier of heat conduction for LED and components,heat dissipation is mainly rely on area,high thermal conductivity can choose the material standard.
Good aluminum material is the base of good quality led products. MOKO can provide you the best aluminum PCB board, Led PCBA and even finished Led products with a reasonable price.
