There are two basic principles to determine the distance between the multilayer capacitor power layer and the edge of the board in the capacitor design of multilayer PCB board, and to solve the distance between the printing strip: 20-H method and 3-W meth
Although the decoupling capacitor can be placed near the through-hole, it is rendered useless at high frequencies due to the lead and through-hole inductance. Such routing will increase the area of signal ring and reduce the current radiation unfavorably.
In case of abnormal tools during transportation, it is necessary to ensure the safety of personnel and goods, and do a good job in isolation and reporting.General principles to be followed in the layout design of multilayer printed boards
Some people have more information about their designed PCB board, so they like to test all the components at once. In fact, it is better to do it bit by bit.
PCB design based on PCB design software can also be regarded as a software development process. Software engineering pays most attention to the idea of "iterative development" to reduce the probability of PCB errors.
There are many forms of pcb files. 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 along to find out!
Compared with traditional electronic circuit board, it not only shortens the production cycle of a single circuit board, but also has greater advantages in production cost and quality.
Selective welding processes include flux spraying, circuit board preheating, dip welding and drag welding. Flux coating process in selective welding, flux coating process plays an important role.
PCB design, not only technology, but also art, art involves a lot of subjective factors, so engineers should also pay attention to improve their own culture.
sinking gold plate and gold plate is the same process product, electric gold plate and flash gold plate is the same process product, in fact, it is just different people in the PCB industry of different names, sinking gold plate and electric gold plate is
The negative film is used for direct etching, and the corrosion resistance left after development is a circuit, which is etched directly with acid etching solution.
The circuitry on the circuit board is designed to bend to ensure the stability of the signal. Circuit board design is a kind of technical work, only using the corresponding design to ensure the stability of the signal.
