Based on the changes in the international trade environment, PCB industry is still under a big test, originally in the capital chain break and environmental pressure impact of small and medium-sized PCB manufacturers, are also accelerating out of the shuf
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.
While this setup is tedious, it's not as bad as an auto-wiring device. Most design teams eventually establish a set of design rules that aim to: standardize bare board construction costs to maximize yield; Assemble, inspect, and test as consistently as po
Unless the constraints of the auto-routing algorithm have been highly fine-tuned by the designer, the auto-routing results still need to be manually checked for weaknesses in the backtracking algorithm results.
The problem is clear. A technically correct but confusing schematic is still a bad schematic." Although this view is easy to accept, in CAD programs, an unreadable schematic diagram can still describe the circuit connection information, and is still ...
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!
Therefore, welding resistance data cannot be generated directly from similar pad. When applying solder resistance, the filler block area will be covered by solder resistance, resulting in difficulty in welding components.
In China, the demand for backplanes mainly comes from the communications industry, which is now growing in the field of communications equipment manufacturing.
Similarly, there is also a parasitic inductance through the hole. In high-speed digital PCB, the harm caused by the parasitic inductance is often greater than the parasitic capacitance.
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.
