Therefore, the combination of soft and hard board, is the flexible circuit board and hard circuit board, after pressing and other processes, according to the relevant process requirements combined together, the formation of a circuit board with FPC charac
How to achieve high PCB spread rate and shorten the design time, which is a lot of people are considering the problem, this time, long Bo technology and you discuss the design skills of pcb board layout.
Before PCBS, circuits were made up of point-to-point wiring. The reliability of this method is very low, because as the circuit ages, the rupture of the line will cause the line node to break or short.
Almost every kind of electronic equipment, from small electronic watches and calculators to large computers and communication electronic equipment, as long as there are electronic components such as integrated circuits, in order to make the electrical int
In order to meet different market needs, pcb board manufacturers can open these different forms of files. Then, what materials need to be prepared before pcb board proofing? Follow long Bo technology to understand!
Anti-interference directly reflects the performance and reliability of the whole system. For PCB design engineer, anti-interference design is the key and difficult point that we must master.
Now, it is more and more convenient for engineers to make Chengdu SMT patches, but the defects in various SMT processes are endless.
The size of PCB is limited by the capability of the equipment in the electronic processing line, therefore, the appropriate size of PCB should be considered in the design of the product system scheme.
Then use these technical documents and production documents to make PCB board, component welding, fly needle testing, circuit board debugging, and complete the complete copy of the original circuit board template.
It's best to take two pictures of the device's location with a digital camera. A lot of pcb circuit boards do more advanced above the diode transistor some do not pay attention to see.
The value of the matching resistance should be determined by the maximum value of the output drive current and the absorption current of the integrated circuit.
Power integrity directly affects the signal integrity of the final PCB board. Power supply integrity and signal integrity are closely related, and in many cases, the main cause of signal distortion is the power system.
