What is PCB Reflow? High-Speed Signal Reflow Path Analysis24 November 2021
Hello everyone, I am Rose. Welcome back to the new post today. The fact that electrons never stay in one place and must return no matter where the current runs are one of the properties of electron flow. As a result, current flows in the loop at all times, and any signal in the circuit exists as a closed-loop.

What is Power Factor Correction (PFC)?10 December 2021
Hello, everyone. I am Rose. Welcome to the new post today. The full English name of PFC is "Power Factor Correction", which means "power factor correction". Power factor refers to the relationship between effective power and total power consumption (apparent power), that is, effective power divided by total power consumption The ratio of the amount (apparent power). Basically, the power factor can measure the extent to which electricity is effectively utilized. The larger the power factor value, the higher the power utilization rate.
