    • China Wholesale Embedded Pcb Quotes - 14 Layer Blind Buried Via PCB – Huihe

      China Wholesale Embedded Pcb Quotes - 14 Layer Blind Buried Via PCB – Huihe

      About Blind Buried Via PCB Blind vias and buried vias are two ways to establish connections between layers of printed circuit board. The blind vias of the printed circuit board are copper-plated vias that can be connected to the outer layer through most of the inner layer. The burrow connects two or more inner layers but does not penetrate the outer layer. Use microblind vias to increase line distribution density, improve radio frequency and electromagnetic interference, heat conduction,...

      Half Hole Technology After the PCB is made in the half hole, the tin layer is set at the edge of the hole by electroplating. The tin layer is used as the protective layer to enhance the tear resistance and completely prevent the copper layer falling off from the hole wall. Therefore, the impurity generation in the production process of the printed circuit board is reduced, and the workload of cleaning is also reduced, so as to improve the quality of the finished PCB. After the production of c...

      Half Hole PCB Splicing Method By using the stamp hole splicing method, the purpose is to make the connecting bar between the small plate and the small plate. In order to facilitate the cutting, some holes will be opened on the top of the bar (the diameter of the conventional hole is 0.65-0.85 MM), which is the stamp hole. Now the board has to pass the SMD machine, so when you do the PCB, you can connect the board too many PCB. at a time After the SMD, the back board should be separated, ...

      China Wholesale Pcb Board Components Quotes - 10 Layer Impedance Control Resin Plugging PCB – Huihe

      Differences Of Electroplating Plug Hole And Resin Plug Hole? Surface difference: The electroplating plug hole is filled by copper plating, and the inner surface of the hole is full of metal. The resin plug hole is filled with epoxy resin after copper plating on the hole wall, and finally copper plating on the resin surface. The effect is that the hole can be conducted, and there is no dent on the surface, which does not affect the welding. The process is different: Electroplating plug hole is...

      China Wholesale Pcb Via In Pad Suppliers - 6 Layer ENIG Impedance Control PCB – Huihe

      About The Impedance Impedance is the combination of capacitance and inductance to block the circuit in high frequency signal. Impedance is a kind of AC characteristic, which means that it is related to frequency and is used to describe the high frequency characteristics of PCB. Factors Affecting Impedance DK (R): determined by raw materials (PCB material, semi cured sheet) Line Thickness (T): determined by raw materials and process capability. Line Width (W): determined by customer’...
