China OEM Pcb Manufacturing Company California - 4 Layer ENIG FR4 Heavy Copper PCB – Huihe
Heavy Copper PCB Heavy copper PCB boards can be manufactured simply by a combination of two main processes, electroplating and etching. In contrast to other PCBS, the circuit is made of a thin layer of copper foil. The heavy copper PCBs are uniformly laminated with FR4 or other epoxy-based material. The average weight of heavy copper PCBs can be 4 ounces (140μm), which is a better ratio than another common copper PCB. The additional copper thickness allows the board to conduct higher cu... -
factory low price Small Prototype Board - 6 Layer ENIG FR4 Tg170 PCB – Huihe
When Need High Temperature PCBs? If the working temperature of the product is higher than 130 ℃, a high Tg PCB is required to ensure safety. The main reason for using high Tg PCB is that the PCB needs to comply with RoHS directive, and the temperature required for lead-free solder flow is high, resulting in the substrate of printed circuit board needs to be high Tg material. Application Of The High Tg PCB TG PCB is used in electronic industry which can run at higher temperature. By providing ... -

Competitive Price for Flexible Pcb - 12 Layer ENIG FR4 Blind Vias PCB – Huihe
HDI PCB Material HDI PCB materials are RCC, LDPE, FR4 RCC:Resin coated Copper is short for resin coated copper foil. RCC is composed of copper foil and resin with rough surface, heat resistance and anti-oxidation treatment (used when the thickness is more than 4mil).The resin layer of RCC has the same processability as FR4 adhesive sheet (prepreg). In addition, it should also meet the relevant performance requirements of the laminate, such as: (1) High insulation reliability and micro via rel... -
Manufactur standard Pcb Manufacturing Supplier - 6 Layer FR4 ENIG Impedance Control PCB – Huihe
Factors Determining Controlled Impedance The characteristic impedance of a PCB is usually determined by its inductance and capacitance, resistance and conductance. These factors are functions of the physical size of the circuit, the dielectric constant and dielectric thickness of the PCB substrate material. In general, the line impedance of a PCB ranges from 25 to 125Ω. The PCB structure that determines the impedance value consists of the following factors: Width and thickness of top and bott... -
