Surface mounting technology, referred to as SMT, as a new generation of electronic mounting technology has penetrated into various fields. SMT products have the advantages of compact structure, small size, vibration resistance, impact resistance, high frequency characteristics and high production efficiency. SMT has occupied a leading position in circuit board assembly technology.
Typical surface mounting process is divided into three steps: applying solder paste - mounting components - reflow soldering
The appropriate amount of solder paste is evenly applied to the PCB pad to ensure that the pad corresponding to the patch components and PCB achieves good electrical connection and sufficient mechanical strength during reflow soldering. The solder paste is a paste with certain viscosity and good contact property, which is made up of alloy powder, paste flux and some additives.
At room temperature, because the paste has a certain viscosity, electronic components can be pasted on the PCB pad. When the inclination angle is not too large and there is no external force collision, the general components will not move. When the solder paste is heated to a certain temperature, the alloy powder in the solder paste melts and flows again. The solder pins of components and PCB pad are infiltrated by Liquid solder. After cooling, the solder end of the component is connected with the pad by solder, forming the solder joint of electrical and mechanical connection.
