It is the latest development in PCB testing technology. It uses a laser beam to scan the printed board, collect all the measurements, and compare the actual measurements with preset qualifying limits.
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
In the process of high-speed circuit design, we must consider how to deal with the radiation of the power supply and the interference to the whole system. Generally, the area of the power layer plane should be smaller than the area of the ground plane, so
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!
The shape is not deformed, so as to avoid the deformation of the shell and dislocation of the screw hole after installation. Now are mechanized installation, circuit board hole location and line and design deformation error should be within the allowable
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.
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.
which also means that the frequency is higher and higher, the requirements of the circuit board substrate is also higher and higher.
In PCB board backwelding furnace prone to plate bending and plate warping, we all know, so how to prevent PCB board backwelding furnace plate bending and plate warping.
