In the process of PCB design, wiring can be roughly divided into three realms: The first is distribution, which is also the most basic requirement of PCB design. If the circuit is blocked, then the basic function of the board is not available, it is a waste board, let alone other things. The second is performance, which is a measure of the quality of a printed circuit board. After the wiring is completed, it is necessary to consider how to achieve the best performance and avoid various...
The two-wire, three-wire, and four-wire systems we reviewed refer to various transmitters whose outputs are imitating DC current signals, and the differences in their operating principles and layouts do not only refer to the wiring method of the transmitter. Otherwise, the thermocouple with millivoltmeter to measure temperature can be called the pioneer of the two-wire system! Let's take a look at their definitions first. Two-wire system: The two wires and the transmission power supply transmit...
For reasons of work, various types of cables, wires, network cables, and cable television lines are often used, but often only a few types are used. The commonly used methods and applications of cables, wires, network cables, and cable television lines are briefly described. induction. First, the meaning of various commonly used letters R-connecting flexible cable (wire), soft structure. V-insulated PVC. V-PVC insulation V-PVC sheath B-flat (flat). S-twisted type. A-tin or silver plating. F-...

As a key component of modern cars, the wiring harness includes thousands of assembly elements that connect various electronic systems together so that they can work together. Any small faults in the wiring harness may affect the entire system. However, in order to cope with the increasing demand for electronic systems inside vehicles, the complexity of automotive wiring harnesses is also increasing, so we urgently need to quickly and easily detect open and short circuits. Line diagnosis is very...
Well-designed bolt-tight connection schemes, proper bolt tightening tools, and effective bolt tightening inspection methods are important factors in ensuring that each bolt in the harness is properly tightened.

What is the battery life of new energy vehicles? Battery life has "dry storage life" and "wet storage life". These two concepts are only for the size of the battery self-discharge, not the actual life of the battery. The true life of the battery is the length of time the battery is actually used. For a primary battery, the life of the battery is a function of the operating time (depending on the magnitude of the discharge rate) that gives the rated capacity. For the secondary battery, the life...
