China Wholesale Pcb Manufacturers - 4 Layer FR4+Rogers PCB 29166 – Huihe
About High-frequency mixed-voltage PCB High-frequency mixed-voltage circuit boards are pressed using different laminated materials to optimize electrical performance and improve system reliability. The biggest challenge in manufacturing this type of high frequency PCB is to match the thermal expansion coefficient (CTE) of the different materials to fit the PCB manufacturing and component assembly. Typically, such circuit designs include a combination of FR-4 materials and PTFE laminated ... -

China Wholesale Multilayer Pcb Board Manufacturers - 4 Layer ENIG Impedance Control PCB 9115 – Huihe
About the impedance control 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 c... -
China Wholesale Double Sided Pcb Board Prototype Pricelist - 6 layer ENIG Impedance Control Heavy Copper PCB 15881 – Huihe
Functions of heavy copper PCB Heavy copper PCB has the best extension functions, is not limited by the processing temperature, high melting point can be used oxygen blowing, low temperature at the same brittle and other hot melt welding, but also fire prevention, belongs to the non-combustible material.

China Wholesale Lcsc Pcb Factories - 8 Layer High TG Impedance Control Fine Pitch PCB 16 – Huihe
Advantages of high Tg PCB 1. Higher stability: if the Tg of PCB is increased, it will automatically improve the heat resistance, chemical resistance, moisture resistance and device stability. 2.Withstand high power density design: if the device has high power density and fairly high calorific value, then high Tg PCB will be a good solution for heat management. 3.When reducing the heat generation of ordinary boards, larger printed circuit boards can be used to change the design and power ... -
China Wholesale High Speed Pcb Factories - 14 Layer High TG Fine Pitch PCB 14 – Huihe
About High Tg PCB The general TG is more than 130 degrees, the high Tg is more than 170 degrees, and the medium TG is more than 150 degrees. 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 ... -
