Factory best selling Microwave Pcb Board - 6 Layer ENIG FR4 Heavy Copper PCB – Huihe
Heavy copper PCB is a layer of copper foil bonded on glass epoxy substrate of printed circuit board. When the thickness of finished copper is more than or equal to 2oz, it is defined as heavy copper PCB. heavy copper PCB has the best extensibility and is not limited by processing temperature. Even in extremely corrosive atmosphere, copper PCB will form a strong and non-toxic passivation protection layer. heavy copper PCB is widely used in various home appliances, high-tech products, military,...

Wholesale Heavy Copper Pcb Manufacturers - 4 Layer FR4 ENIG Impedance Control PCB – Huihe
Impedance Control PCB In the case of transmission of high frequency signals, the controlled impedance helps to ensure that the signal does not decay significantly during transmission. In essence, controlled impedance refers to the matching of the material properties of the substrate to the characteristics of the line/dielectric layer to ensure that the impedance value of the line signal is within the tolerance of the reference value. Controlled impedance PCBs provide reliable and consist...

Hot sale 6layer Security Enig Pcb Board - 4 Layer FR4 OSP Impedance Control PCB – Huihe
Characteristic Impedance Control PCB The characteristic impedance of the conductor on the PCB is an important index of circuit design, especially in the PCB design of high frequency circuit, we must consider whether the characteristic impedance of the conductor is consistent with the characteristic impedance required by the device or signal. PCB Impedance Matching In the PCB, if there is a signal transmission, it is expected to be from the sending end of the power supply, in the case of minim...

Manufacturer of China Led Printed Circuit Boards - 8 Layer ENIG FR4 Multilayer PCB – Huihe
The Difficulty Of Multilayer PCB Board Prototyping 1. The difficulty of interlayer alignment Because of the many layers of multilayer PCB board, the calibration requirement of PCB layer is higher and higher. Typically, alignment tolerance between layers is controlled at 75um. It is more difficult to control the alignment of multilayer PCB board because of the large size of the unit, the high temperature and humidity in the graphics conversion workshop, the dislocation overlap caused by t...

Factory made hot-sale Rigid Flex Pcb Supplier - 14 Layer ENIG FR4 Tg170 PCB – Huihe
About High Tg PCB The general TG is more than 130°, the high Tg is more than 170°, and the medium TG is more than 150°. Generally, PCB with TG ≥ 170 ℃ is called high Tg PCB. When the Tg of the substrate is increased, the heat resistance, moisture resistance, chemical resistance, stability resistance and other characteristics of the circuit board will be improved. The higher the TG value, the better the temperature resistance of the sheet, especially in the lead-free process, the application o...
