There are three main forms of circuit protection: overvoltage protection, overcurrent protection, and overtemperature protection.
When doing radio frequency, pay special attention to their Q value when selecting inductors and capacitors. So what is the Q value?
When learning about current and voltage sources, the issue of internal resistance in the power supply often confuses many people, only remembering that when the voltage source is connected to an exter…
Today qihe smt pick and place machine sharing the Application and Principle of Pressure Sensors in Industry .
Hello everyone, today we will learn about a customer case of operating lithium battery protection board on the customized modules completed by small automatic smt machine line ,TVM925s pick and place machine ,stencil printer QP3250,T960 reflow oven and pcb conveyor .
In some industrial applications, many capacitor banks are often used, which are equipped with protections such as quick break, overcurrent, overvoltage, and voltage loss. However, there may still be tripping caused by capacitor faults. What is the problem and how to solve it?Today qihe smt pick and place machine sharing how to solve the problem of tripping due to capacitor failure .
Avoid penalties for non-compliance–Designers need to follow regulations regarding electromagnetic compatibility (EMC) when designing PCBs because failing EMC testing could lead not only do fines but also to loss of customer trust which could cause irreparable damage even if those penalties eventually get waived.
Radio frequency is measured in units called hertz (Hz), which represent the number of cycles per second when a radio wave is transmitted. One hertz equals one cycle per second; radio waves range from RF Interferences,Mobile Phones,pick and place machine
Decoupling capacitors should be placed as close as possible to the source for the signal being decoupled. This means at the pin for ICs and near the connector for input and out signals. To remove LF transients from input and output signals, the capacitor should be placed in series with the trace.
