Thyristor, commonly known as SCR, its standard term is reverse blocking three terminal thyristor. Thyristors are high-power semiconductor devices with switching and rectifying functions, and are used in various circuits, such as controllable rectifying and converting, inverter and contactless switch. As long as it provides D and weak trigger signals, it can control the strong current output. Therefore, it is a bridge for semiconductor devices to enter the strong field from the weak field.Continue reading What is Thyristor and How it Works?

Although there are many uncertainties in the theory of RF circuit board design, there are still many rules that can be followed in RF circuit board design. However, in the actual design, the real practical skill is how to compromise these rules when they cannot be implemented due to various limitations. This paper will focus on various issues related to RF circuit board partition design.Continue reading Some Skills for RFID Circuit Board Design
It is believed that many people are not unfamiliar with PCB, they may hear it often in daily life, but they may not know PCBA very well, or even be confused with PCB. So what is PCB? How did PCBA evolve? What is the difference between PCB and PCBA? Let’s learn more about it.Read more
