Friends working in the SMT industry know that many SMT defects are caused by issues with solder paste printing. To better control the quality of printed solder paste, Solder Paste Inspection (SPI) has emerged as a solution. SPI uses high-precision red laser projection and a high-resolution digital camera to monitor the printing quality of solder paste and reduce defects.
SPI is usually placed after the SMT solder paste printing machine. After the PCB solder paste is printed, it is transmitted to the SPI through the track for inspection. This can improve the SMT yield and help to screen out PCB boards with poor printing solder paste.
The role of SPI in SMT
Due to the precision and miniaturization of electronic products, quality requirements for PCB surface printing solder paste during component mounting are very high. Detecting the quality of solder paste printing before SMT can be more effective than detecting it after SMT reflow bonding. This can help to prevent poor PCBA boards and reduce repair costs.
The content of SPI testing includes solder paste printing quantity, thickness, area, flatness, offset, pointing, and connection. SPI plays a crucial role in quality control in the SMT contract manufacturing process, and if used effectively, it can improve product quality while reducing manufacturing costs.
SPI is not only used to prevent the quality of solder paste printing but also to control and prevent maintenance costs in the later stages. This helps to improve production capacity and increase profits. With the precision of electronic manufacturing products, the quality of printed solder paste has become increasingly important. SPI can effectively ensure good solder paste printing quality and significantly reduce potential quality risks.
