Factory directly supply 16 Layer Pcb Manufacturer - 8 Layer FR4 ENIG Impedance Control PCB – Huihe
Impedance is the combination of capacitance and inductance to hinder the circuit under high frequency signal. Impedance is an AC characteristic, which means it is frequency dependent. In the case of transmitting high-frequency signals, the controlled impedance helps to ensure that there is no significant attenuation of the signal during transmission. In essence, the controlled impedance means that the material characteristics of the substrate match the characteristics of the line/dielectric l... -

Manufacturer of 14 Layer Circuit Board Manufacturer - 10 Layer ENIG FR4 Via In Pad PCB – Huihe
Via In Pad PCB In PCB design, a through-hole is a spacer with a small plated hole in the printed circuit board to connect the copper rails on each layer of the board. There is a type of through-hole called microhole, which only has a visible blind hole in one surface of a high-density multilayer PCB or an invisible buried hole in either surface. The introduction and wide application of high-density pin parts, as well as the need for small size PCBS, have brought new challenges. Therefore... -
