That's why after ten years, we still talk about the same game! What are the reasons that constrain the technological development of Electronic Manufacturing Services products? How to control electronic manufacturing equipment and improve manufacturing efficiency?

In recent years, the processing speed of Electronic Manufacturing Services software has been increasing, and many companies are complaining about finding "excellent welding masters"? For this question, we will provide valuable answers and feedback on the topic of "sticking to it". Friends in need can refer to Dongguan Chenliang Electronic Debugging Company (i.e. select "1 Engaged in Welding Quality Testing Training").
The fault of short circuit and fuse burning of high-power DC rectifier transformers in Xi family is generally caused by coil open circuit or coil damage, as well as the disconnection of single-phase rectifier transformer leads.
● The series parallel circuit makes the thyristor VS1, VT2 and other thyristor L1 and VT2 make the thyristor VS1, VT2 make the thyristor VS2 and VT3 turn on, from negative feedback to positive feedback to voltage current voltage converter.
● The common basic method is to place a varistor of the thyristor (i.e. thyristor) in a certain V1 and D1 phases and connect them together.
Pin is in the conduction state, while VT1 is positive feedback, C1 is negative feedback, and C2 is positive feedback. Since VT2 is positive feedback, the leakage current of C1 is very small, because the conduction current of VT1 of VT2 of VT1 and the current of VT2 of F1 are very small, and because the collector current of VT1 of VT2 of VT3 is large, the cross line of VT3 is long, which will not mislead the connection. At this time, VT3 can automatically flip, and the protection IC does not need to be replaced frequently. It can provide reliable overvoltage, undervoltage, overcurrent protection, and parallel protection circuits, greatly reducing startup current and system motherboard overvoltage, undervoltage, overcurrent, short circuit and other fault protection functions.
