Thick Copper PCB

Thick copper PCBs are characterized by structures with copper thicknesses from 105 to 400 µm. These PCBs are used for large (high) current outputs and optimization of thermal management. The thick copper allows large PCB-cross-sections for high current loads and encourages heat dissipation. The most common designs are multilayer or double-sided. With this PCB technology it is also possible to combine fine layout structures on the outer layers and thick copper layers in the inner layers. Advantages of Thick Copper PCB:
Thick copper PCB is widely used in various household appliances, high-tech products, military, medical and other electronic equipment. The application of thick copper PCB makes the core component of electronic equipment products-circuit boards have a longer service life, and at the same time it is very helpful to the size reduction of electronic equipment.

PCB shall be immersed in the molten solder during hot air solder leveling. The air knife shall flush the liquid solder before the solder solidifies, and it can minimize the crescent shape of the solder on the copper surface and prevent the solder bridge.

Layer: 4  SolderMask Color: GreenSilkscreen Color: White  Width/Space: 0.1/0.1mmSurface treatment: ENIGSpecial Technology: Impedance controlThis PCB board is panalized by 4 pieces, using by Immersion Gold is to process the color more bright. And depositing the color on the surface very stable. The advantages for Immersion Gold is to make the coating very flat.The solderability is very good. Impedance control (EImpedance Controlling). There will be a variety of signal transmission in the conductors in the circuit board, to increase its transmission rate must increase its frequency. If the line itself due to etching, stack thickness, wire width, and other different factors. The impedance is worth changing, and the signal is distorted.
