Qatar World Cup, a big upset! Saudi Arabia scored two goals in 5 minutes of the second half, reversed 2-1 and defeated Argentina in an upset!
VIEW MORE+The shape recognition of electronic components is to correspond to the physical object and the name. The purpose is to get an electronic component to know what it is and its circuit graphic symbol.
VIEW MORE+Environmental conditions such as high ambient temperature, exposure to mechanical shock, and specific drive cycles require special attention to the mechanical and electrical characteristics of IGBT power modules to ensure that their performance is fully developed and maintained throughout its service life. High reliability. This article discusses the power and thermal cycling of IGBTs.
VIEW MORE+First, the failure characteristics of electronic components
VIEW MORE+Among components, capacitors can be said to be components with complex types and specifications, especially in order to adapt to different circuits and different working environments, even capacitors with the same capacity and rated voltage have various types and material characteristics. s Choice. If a capacitor fails, the usual solution is to replace it with a new capacitor of the same size. But what if I can't find a capacitor of the same specification
VIEW MORE+Install the resistor in the specified position according to the diagram. The mark is required to be upward and the word direction is consistent. After installing the same specification, install another specification, and try to make the resistors as high and low as possible. After soldering, cut off the excess pins exposed on the surface of the printed circuit board.
