I. What is SPI equipment?
SPI is solder paste inspection machine, is the SMT assembly line solder paste printing inspection link. In its production process, most of the defects are derived from the printing process steps. With the continuous progress of modern technology, more and more small, precise parts such as BGA, QFN, connectors and 0201, etc. are widely used, the quality control of solder paste printing has become more and more critical. To ensure product quality, SMT SPI equipment has been commonly integrated into SMT assembly lines, replacing traditional manual inspection methods.
SMT SPI machine is able to accurately detect multiple critical areas of solder paste printing, including print volume, height, area/volume, and flatness. It can also determine whether the solder paste printing offset, height deviation (pull tip), bridging, defects, broken or collapsed and other issues.
II. The main role of SMT SPI machine is reflected in the following aspects
1. Quality control
SMT SPI machine can carry out comprehensive and accurate inspection of the quality of solder paste printing to ensure that the uniformity of solder paste printing, height, area, volume and other key parameters in line with production requirements. This helps to identify and correct problems in the printing process in a timely manner to ensure that the subsequent SMT machine placement, reflow oven soldering and other processes run smoothly.
2. Defect prevention
Through SMT SPI machine inspection, potential problems in solder paste printing such as offset, tip pulling, bridging, defects, breakage, collapse, etc. can be found in time. These problems, if not dealt with in a timely manner, will seriously affect the yield of SMT soldering, the introduction of SPI helps to find and solve these problems before soldering, thus preventing defects.
3. Increase productivity
SMT SPI machine is able to carry out quality inspection immediately after the printing of the solder paste printer, once found defective products, can be reworked or adjusted immediately. This avoids the flow of defective products into subsequent processes, reducing unnecessary waste and rework time, thus improving the productivity of the entire SMT processing process.
4. Cost Reduction
Through SMT SPI machine inspection, costs for rework, repair and scrap due to defects are avoided. At the same time, the use of SMT SPI machine also reduces the need for manual inspection, reducing labor costs.
5. Improve product throughput
The introduction of SMT SPI machine helps to identify and solve potential problems in the early stages of SMT processing, thus improving the throughput rate of products, and more products can pass through all production stages at once, reducing the number of reworks and repairs caused by quality problems.
With SMT SPI machine, boards with poor solder paste printing and various problems can be accurately identified during SMT processing and further traced back to the root cause of the problem.
