Led Circuit Board Main Technical Characteristics
Led circuit board main technical characteristics and application: electrical insulation performance is stable, good flatness, smooth surface, no pits, thickness tolerance over the standard, LED PCB suitable for high-performance electronic insulation requirements of the product.
Glass fiber board because of its good material properties, LED PCB in the conventional electrical, electronic, digital products, the most widely used.
Aluminum plate: LED aluminum plate is used in aluminum-based materials, the thermal conductivity than ordinary FR4 material is better, to adapt to the requirements of many high-power electrical appliances, LED PCB most of the current aluminum plate for LED lighting production by led pcb board manufacturer.
PCB assembly Printed circuit board is the abbreviation of printed circuit boards, LED aluminum plate and FR-4 glass circuit boards are the same PCB, to say different, just take LED aluminum plate and FR-4 glass circuit board comparison, LED aluminum plate is in Thermal conductivity of the aluminum plane on the print line, LED PCB and then welded to the top of the electronic components.
The main purpose of using aluminum substrate is that he has a good heat dissipation, high power LED due to relatively large heat, so most of the aluminum plate for LED lighting production. FR-4 glass fiber circuit board is the traditional electronic products circuit board, because of good insulation, corrosion resistance, compression, multi-layer printing and other characteristics, widely used.
LED aluminum substrate product quality is mainly considered aluminum material model, hardness, surface and thickness, but also according to the product of the heat to choose the appropriate model size. FR-4 fiberglass circuit board is a relatively mature product, LED display on the use of FR-4 are all kinds of glass fiber circuit boards.
