Introduction to Passive ComponentsAccording to Xiao Bian learned passive component (passive component) is an electronic component, relative to the active component, is not affected by the basic characteristics of the signal, but only through the signal without changing the circuit components. Do not need the source of energy to implement his specific function. Examples of passive components include resistors, capacitors, inductors, diodes. The traditional quartz wireless receiver, an amplitude modulated wireless receiver does not require any power, is entirely composed of passive components.Pa...

Introduction to active componentsXiaobian known active components (active component) active device is in the analog and digital circuits in the external signal, you can change their own basic characteristics of the device is obtained by the current direction, or rely on the current direction of the components. A component capable of performing a data operation and processing in a circuit element. Simply said is the need to (power) source device called active devices, active devices are generally used to signal amplification, conversion, passive devices used for signal transmission, or through ...

Ceramic chip capacitors (MLCC) widely used, if visible or not visible cracks will lead to circuit failure, or even a very serious loss of events. Common breakdown after the phenomenon of power is mostly crack causes, I hope this article can readers have a relatively large reference value.The improper welding conditions on the board are important causes of MLCC cracks.Ceramic chip capacitors (MLCC) ceramic and metal combination. Ceramic body part of the poor thermal conductivity, by the rapid cooling and hot cases, the ceramic body is prone to macro-cracks. The metal electrode part of the therm...

Welding of components1. Welding requirements with conventional welding processesComponents of the welding, the main note is: master the heating time, using the appropriate temperature and good operating action. Different components of welding, in different temperatures, air flow and other environments, the use of different soldering iron and soldering iron, to master the three aspects of the skills are also different, which requires us to work in a lot of practical exercise And improveWelding should be the first component pins, PCB pad oxide removed, if necessary, the first on the tin, inconve...
