FR4 TG180 pcb circuit board
Layer: 4 SolderMask Color: Green Silkscreen Color: WhiteSurface treatment: Leard free HAL          Board Thickness: 1.6mm                Min Hole Size: 0.3mm                  Min line width/ space: 0.2/0.2mm                    Application: power supply According to the lead-free tin spraying and immersion tin process flow. It can be known that the test station in the lead-free tin spraying process flow is after the lead-free tin spraying process. Even if there is a defect in the lead-free tin spraying process, it can be detected in the subsequent test. So it can better ensure the function of PCB circuit board products. The surface of lead-free tin spray is brighter and beautiful, while the surface of tin sink is pale white and dull. The performance and function of lead-free tin spray products are more stable and reliable.

Thick pcb copper plating circuit board
Layer: 12 Surface treatment: Leard free HAL  Board Thickness: 2.1mmMin Hole Size: 0.3mmMin line width/ space: 0.2/0.2mmParticularity: resin plug hole, depth control drillApplication: power supply This PCB board is panalized by 2 pieces, surface treatment is Leard free HAL. . 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.

High and Multi-Layer PCB Board
layers: 18SolderMask Color: Green   Thickness: 5.4±0.5mmBorehole thickness -diameter ratio: 5.3133Surface treatment: ENIGApplication: transformer This printed circuit board is used for transformer, the surface treament is ENIG. A board used for transformer, needs to go through high temperatures. The usage of ENIG is to achieve good electrical performance in the long term use of PCB. The general process is pickling cleaning → micro-etching → pre leaching → activation → electroless nickel plating → chemical leaching.

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.

Layer: 8 SolderMask Color: Green Silkscreen Color: White  Thickness: 1.6mm±0.16Special Technology: Rogers+FR4,Rf antenna line width control +/-5um PCB manufacturers have also begun to study the processing of various high-frequency products and the application of low-cost solutions, such as high-frequency products. The mixing of high-frequency materials and ordinary FR-4 is to embed high-frequency materials in ordinary FR-4 materials. However, this method has problems such as poor flatness of the board formed by high-frequency materials and FR-4 materials. Resulting in large size of the shielding cover is poorly attached and the problem of welding gaps.
