The SMT reflow soldering process includes pre-heat, soak, reflow, and cooling zones. The pre-heat zone gradually heats up to about 150°C to evaporate moisture and activate the flux in the solder paste. The soak zone maintains a temperature of 150±10°C to remove volatiles and uniformly heat components. The reflow zone, the hottest area, melts the solder paste and forms intermetallic compounds. The cooling zone controls the cooling rate to prevent component damage. Precise control of temperature and time in each zone is crucial for ensuring soldering quality. Read More

In the process of circuit design, some circuits that require timing or delay are often encountered. For precise timing, many chips or MCU internal timers on the market can be implemented, but for some timing that does not require too precise. Based on the principle of cost saving and energy investme Read More

The bus system is undoubtedly one of the essential components of electronic circuits. As a bridge between electronic systems and the external world, the bus system is indispensable. Among them, SPI, I2C, and UART are the three commonly used bus protocols. However, many people believe that they have Read More

Simply put, a PCB is a thin plate with integrated circuits and other electronic components. It will appear in almost every electronic device, and it is the basis of the entire electronic product, so it is particularly important.This article summarizes some common design mistakes in PCB design for yo Read More

The temperature zone standard of SMT reflow soldering, generally speaking, the standard SMT reflow soldering is eight temperature zone reflow soldering. Of course, there are SMT reflow soldering machines in several temperature zones in actual use. This is based on the actual soldered products and SM Read More
