What is the history of pcb circuit board? What categories does it fall into?
On the most basic PCB, the parts are concentrated on one side and the wires on the other. Because wires appear on only one side, this type of PCB is called Single-sided.

The medical field is one of the most sensitive applications requiring PCBS because it requires precision, reliability, and high quality components. For this reason, medical PCBS are specifically designed to suit specific environments, laboratories, and te
In some cases, the layout and safety considerations involved in high-current board design are similar to those in high-voltage design, especially when we consider safety.
The function of PCB design is to standardize the design operation, improve the production efficiency and improve the quality of electronic products.
PCBA three anti paint coating methods: 1, impregnation, 2, spraying, 3, brush coating, 4, selective coating
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
Due to the number of high-rise board layers, the customer design end of PCB layer alignment requirements are more and more strict, usually the inter-layer alignment tolerance control ±75μm, considering the large size design of high-rise board units, graph
Components with large heat or current should not be placed in the corners and edges of PCB board, and radiators should be installed as far as possible, and away from other devices, and ensure that the heat dissipation channel is smooth.
The impedance and loss of PCB are crucial to the transmission of high-speed signals. In order to analyze such a complex transmission channel, we can study its impact on signals through the impact response of transmission channel.
Hot air smoothing is to dip the printed circuit board into the molten solder (63SN/37PB), and then use the hot air to blow off the excess solder on the surface of the printed circuit board and in the metallized hole, to obtain a smooth, uniform and bright
Compared with the dip welding process, the motion of solder solution and PCB board in the drag welding process makes the thermal conversion efficiency better than that in the dip welding process.
