All of these problems can cause the solder shield to detach from the circuit board and eventually lead to corrosion of the copper circuit. Poor insulation due to thin solder resistance layer can cause short circuit due to unexpected conduction/arc.
PCB has become the most important and key part of electronic information products. Its quality and reliability level determine the quality and reliability of the whole equipment.
That is: the actual out of the board is the circuit diagram to the right edge line as the reference line to the right after 180 degrees of the page. Pay special attention when there is a blank space! Otherwise the board is useless!
In China, the demand for backplanes mainly comes from the communications industry, which is now growing in the field of communications equipment manufacturing.
Характеристический импеданс: также известный как «характеристическое сопротивление», это не сопротивление постоянному току, относится к концепции передачи по длинной линии.
In addition to the production process, the storage of PCB board parts at each station also has a certain impact on the deformation. In some manufacturers, due to more production waiting and narrow site, multiple boards will be stacked together for storage
It has many advanced features, capable of simulating laminar and turbulent flow as well as multi-type analysis, including radiation and convection. Icepak offers a huge library of fans, radiators and materials that provide solutions to everyday electronic
That is to say, ordinary PCB substrate materials at high temperature, not only produce softening, deformation, melting and other phenomena, but also show a sharp decline in mechanical and electrical characteristics.
The PCB industry will benefit a lot in the industrial chain. With the emergence and rapid progress of 5G communication technology, a number of related fields are entering the situation of technology iteration and product application upgrade simultaneously
What is the core power supply, is some power supply current, the number of the kind. A plane, not more than 3 power supply division. It is important to consider that segmentation cannot present current-carrying bottlenecks.
PCB copper wire falling off (also often said copper dumping) is bad, PCB factories are said to be the problem of laminate, requiring its production factory to bear bad losses.
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.
