Ground mode in multilayer PCB board
In the ground plane segmentation and signal routing, the distribution of ground plane and important signal routing should be taken into account to prevent the problems caused by the ground plane slotting.

How to ensure PCB board height thickness diameter ratio, small aperture connectivity
The removal of copper from the through-hole can be caused by chemical factors, such as etching, or mechanical causes, such as blow-holing, stress cracking, or deposition detachment.
How to solve signal reflection in high speed PCB board design
In a high speed PCB, wiring is more than just connecting two points. As a qualified engineer, wiring is a hybrid knowledge carrier including resistance, capacitance and inductance.
Plasma surface pretreatment in PCB board manufacturing process
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.
What is the function of PCB board printed circuit surface plating process
the current motherboard, memory and graphics card and other equipment "gold finger" is almost all made of tin material, only part of the high performance server/workstation accessories contact point will continue to use gold plating, the price i...
Why should the PCB board be blocked?
This process can ensure that the oil cover through the hole is good, the plug hole is smooth, the wet film color is consistent, the hot air leveling can ensure that the through hole is not tin, no tin beads in the hole, but it is easy to cause the ink pad
Why is the common PCB board thickness 1.6mm
as PCB substrate epoxy resin (see the column of PCB substrate resin chapter), PCB substrate reinforcement materials, copper foil and other manufacturing technologies have not realized commercial production.
PCB board, the rules are very particular
Otherwise, you may be forced to make modifications and redesign your PCB stack structure.
Cause analysis of PCB board defects
This will break the solder joints, bend the shape of the board, or it may cause the copper thread on the board to break.
Four reasons for PCB board copper throwing
it will also lead to insufficient bonding force between copper foil and substrate after laminate, resulting in positioning (only for the large plate) or sporadic copper wire loss, but the stripping strength of copper foil near the stripping line will not
The surface treatment technology of PCB board and its advantages and disadvantages and application scenarios
The circuit board inside the line is mainly pure copper, that is, bare copper plate. Some people think that the gold color is copper, which is the protective layer on the copper.
The analog signal wiring area is distributed on both sides of the PCB board
