How to solve the problem of tripping due to capacitor failure
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 .
How to Optimize PCB Design for EMC Compliance?
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.
Analysis of Internal RF Interferences in Mobile Phones
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 Capacitor Placement in PCB Layout
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.
