prototype led single-side DOB aluminium pcb
Product Description
What are the advantages and disadvantages of aluminum substrate?
Aluminum base plate is a kind of metal base copper clad plate with good heat dissipation function. It is generally composed of three layers of structure, namely the circuit layer (copper foil), the insulation layer and the metal base layer.
Often used in LED lighting products.Low Cost Prototype PCB
First, the advantages of aluminum substrate
1, more suitable for SMT process;
2. Comply with RoHS requirements;
3. Effectively deal with the heat dissipation, reduce the operating temperature of the module and improve the reliability;Quick-turn PCB fabrication
4, reduce the radiator and other hardware assembly area, reduce the product volume, reduce hardware and assembly costs;
5. Good mechanical endurance. Fast PCB Manufacture Low Cost
Two, the shortcomings of aluminum substratePCB Express with 2 day
1. High cost: compared with other commodities, the price of aluminum substrate accounts for more than 30% of the product price.
2, usually can only do a single panel, do a double panel process is difficult.
3, the product is easy to have problems in electrical strength and pressure resistance.
4, aluminum base in the plate pressure index will easily cause substandard.
5, the thermal conductivity test method and test results do not match.
6, aluminum substrate material specifications are not unified, there are CPCA industry standards, national standards, international standards, etc.
7, copper foil thickness is not up to standard, will lead to burning circuit, etc.custom pcb fabrication
More and more defective products, jerry-built, shoddy, stealing beams for columns.
