PCB production process is revealing
The fabrication of PCB is very complicated.
PCB board different material
According to PCB board reinforcement materials are generally divided into the following categories:

For electronics students, it's natural to have test points on a electric circuit board, but for mechanics, what are the test points?
10 important rules for PCB board layout
In PCB design, wiring is an important step in completing product design, and it is also the most detailed and highly qualified step. Even experienced engineers are also a headache for wiring.
Electric circuit board system classification
The automatic detection technology of the professional printed circuit board is applied with the introduction of surface mount technology, and the packaging density of the circuit board is rapidly increased.
