PCB circuit boards play an important role in life today. It is the foundation of electronic components and the highway. In this regard, the quality of the PCB is critical.To check the quality of a PCB, a number of reliability tests must be performed. The
With the reduction of the aperture, the original debris that has no effect on the larger aperture, pcb board factory, such as brush debris, volcanic ash, once remaining in the hole, will make the chemical precipitation of copper, copper plating will lose
If the two reference planes (i.e. the path where the signal returns) have the same potential and the two layers are joined together multiple times through the holes, then the specified return path will have a small loop area. This is the design we wanted.
What is causing concern is the unpredictability of the noise itself. Typically, the noise may come from an external source or an internal source. Even the source of the noise poses more problems.
The next stage is product implementation. At this stage, product documentation is collected and compiled, including all manuals, catalogs, and related product documentation.
The adoption of high speed PCB design means constitutes the controllability of the design process, only controllable, is reliable, can also be successful!
The diode junction capacitance forms high-frequency attenuation oscillation, and the equivalent series inductance of the filter capacitor weakens the function of the filter.
The configuration of decoupling capacitance can suppress the noise caused by load changes, which is a common practice in the reliability design of printed circuit boards.
PCB ink quality is excellent, in principle can not be separated from the combination of the above major components. Ink quality is excellent, is the formula of science, advanced and environmental protection of the comprehensive embodiment.
With the increasing complexity of electronic equipment and the need for more and more parts,PCB board lines and parts are increasingly dense. A board with no parts on it is called a "bare board" and is often called a "printed circuit board&...
Solder paste printing is very important to PCBA in PCBA processing, which directly determines the overall welding effect of PCBA. In the process of PCBA processing, the printing effect of solder paste includes steel mesh, solder paste, printing process, d
The best way to learn about actual system testing for Chinese students is to visit PCBA processing plants where companies develop products with similar lifestyles and inspect the entire production line, from the circuit board to the shop floor to product
