The parameters of PCB board layer, the distance between signal wires, the electrical characteristics of the driver and receiver end, and the connection mode of signal wires all have a certain influence on the crosstalk.
The input and output impedance of the IC after replacement should match the original PCB circuit; Check its driving ability,
whether it is dry method or wet method, if suitable method is selected according to the characteristics of the main material of the system, the purpose of drilling and etching of rigid torsion interconnection mother plate can be achieved.
In addition, before the solder resistance film coating, the printed circuit board surface is treated by plasma, and a certain roughness and high activity surface can be obtained, so as to improve the adhesion of the solder resistance film.
it is easy to drill solder from the end of the covering layer to under the covering layer, especially when the bonding strength of the covering layer and copper foil surface is low, this phenomenon is more likely to occur frequently.
The multilayer soft PCB board made of polyimide film as the base material is about 1/3 lighter than the rigid epoxy glass cloth multilayer PCB board, but it loses the excellent flexibility of single-sided and double-sided soft PCB. Most of these products
The advantage of performing reception equalization in standalone devices is that it provides optimal wiring advantage and design flexibility.
There is no denying that current industry trends and consumer demands are pushing designers and design teams to push the envelope and develop new electronic products to meet market challenges.
The current approach is to increase the distance between the two signal layers and make the lines of the two layers as vertical as possible to avoid signal crosstalk between layers.
The inner laser hole needs to be electroplated and filled, and then the outer laser hole is made. The price is more expensive than the error hole.

For the sticker tantalum capacitor, it is generally three capacitors on the circuit board, the left side is negative, the right side is positive. The middle one is the most vivid.
