How to Improve the Integrity of PCB Signal in Embedded System
The parameters of PCB board layer, signal line spacing, electrical characteristics of driver end and receiver end, and baseline end mode all have certain influence on crosstalk.

The automotive PCB industry, the "skeleton" of intelligent vehicles, is rising rapidly
In terms of land concessions, tax incentives, free recruitment and other aspects, the enterprises in the east have a great attraction, and the "flowering" momentum of PCB industry in the west appears.
Causes of PCB board bending and warping and methods of prevention
In fact, the biggest source of stress in Reflow process is "temperature", which not only makes the circuit board soft, but also distorts the circuit board. This, coupled with the material properties of "thermal expansion and cold contractio...
Analysis of the real cause of PCB board explosion and countermeasures
the Tg value will decrease after baking PCB is also a problem. A better method is to control the water absorption conditions from the selection of PCB board and the manufacturing process.
The important factor affecting the quality of PCB isolation film
Multi-layer PCBS stored for more than three months may show stress concentration (from pressing) and water absorption (which will increase Z expansion).
Three elements of EMC suppression in PCB
With both analog and digital functions of the circuit board, analog and digital are usually separated, only connected at the power source.
Good testability of mechanical contact conditions
In addition, unused gate circuits are often used for design improvements later, and they may be converted into circuits.
About flash memory and other programmable components
Therefore, the boundary scanning method has special advantages when there is no test model or the nodes of the contact circuit are limited.
Price and cost standard of circuit board
Many companies have started to set up a circuit board pricing program on their Web sites, with rules that allow customers to freely calculate prices. People who do not understand PCB can also easily calculate the price of PCB.
How to debug the newly developed circuit board?
For the new PCB board we just got back, we should first observe roughly whether there are any problems on the board, such as whether there are obvious cracks, short circuit, open circuit and other phenomena.
Development prospect analysis of PCB industry in China in 2018
The use of impedance circuit board with reputation is solving many real problems for people, for the safety of very concerned manufacturers, choose a impedance circuit board manufacturers matching their own products for cooperation, can ensure the safety
Slice analysis
At this point, scanning acoustic microscope shows its special advantage in nondestructive detection of multilayer high density PCB. And the general obvious explosion plate is only through the visual appearance can be detected.
