Do you know the advantages of multi-layer PCB boards?

Multi-layer circuit boards are generally used in high-speed PCB design  and the multi-layer circuit board is actually made by several etched single or double circuit boards through laminating and bonding, Multi-layer PCB has many advantages over single and double-sided PCBs,especially in small-size electronic products. Today let's talk about the advantages of multi-layer boards,compared with single and double-sided PCBs 1) Multi-layer circuit boards have high assembly density and small size. With the size of electronic products getting smaller and smaller,higher requirements are put forward on the electrical properties of PCB and the demand for multi-layer printed circuit boards is also increasing 2)The use of multi-layer circuit boards facilitates wiring and layout, the wiring length is greatly shortened, and the wiring between electronic components is shortened, which also increases the speed of signal transmission. 3) For the high-frequency circuit, after adding the ground layer, the signal line will form a constant low impedance to the ground layer, the circuit impedance is greatly reduced, and the shielding effect is better. 4) For electronic products...

Why does PCB need to do impedance control ?

Today, let's talk about why the PCB board needs to do impedance control and what is the meaning of impedance control for the PCB board  1.Why does PCB need to do impedance control ? The pcb board impedance refers to the resistance and the parameters of the reactance, which hinder the AC. Impedance control processing is essential in the production of PCB  industry. Reasons are as follows: 1)As we all know,the PCB need to do mounting of electronic components, So,we should consider the conductive performance and signal transmission performance after mounting,So it will require the lower the impedance, the better. 2)In the production process, PCB boards are subjected to manufacturing steps such as copper plating , electroplating tin ,and soldering. In the meanwhile,the materials used in these process steps must be  low resistivity enough to ensure that the overall impedance control of the PCB board is low and meets product quality requirements. 3)There are various signal transmissions in the conductor layer of the PCB board,when you want to increase signal transmission speed rate,...
