What is SMT solder paste inspection machine

SPI is solder paste detection in SMT patch processing, ensuring solder paste quality, preventing defects, improving manufacturing efficiency, and automatically detecting and recording data. It is essential for SMT production

How many types of SMT SPI are there?

SMT SPI equipment is mainly divided into two types: offline machines and online machines. Offline machines are usually used to detect finished products, while online machines are directly integrated into the production line to monitor problems in the production process in real time.

Offline SPI equipment is mainly used to detect finished products. They can be used at the end of the production line to ensure welding quality by measuring the thickness, area and volume of solder paste. Such equipment usually has high accuracy and flexibility and is suitable for a variety of different production environments.

Online SPI equipment is directly integrated into the SMT production line to monitor the printing quality of solder paste in real time. They usually use high-precision optical instruments and intelligent software to detect defects in the production process in time and prevent problematic products from flowing into the next process. Online SPI equipment is easy to operate and suitable for the automation needs of large-scale production lines.

Main functions of SMT SPI

The main function of SPI is to detect whether the height, volume, area, short circuit and offset of solder paste after printing are qualified. Through SPI equipment, inspection can be performed after solder paste printing, and poorly printed PCBs can be screened out before patching, thereby improving the pass rate after reflow soldering and saving costs.

Specifically, SPI can accurately measure the height, area, shape and position of solder paste through high-precision cameras and advanced image processing technology. It collects and analyzes images of solder paste spots to determine whether the thickness, shape, position offset, etc. of the solder paste meet the specification requirements. This helps to detect solder paste defects, quality problems and bad conditions early, and take corrective measures to improve welding quality and product reliability.

What are the precautions for SMT solder paste inspection machine?

When using SMT SPI (Solder Paste Inspection), the following core matters need to be paid attention to:

1. Confirmation and inspection of track width: Each time the line is changed, the board should be transferred in advance to confirm whether the track width is appropriate and whether the board will be stuck. At the same time, the MARK point should be inspected in advance to facilitate production line operations.

2. Adjustment of sensor sensitivity: Take out space from each line, take two colors of PCB circuit boards to sense, and use tools to adjust the sensor sensitivity appropriately, which can effectively sense the black PCB board, and will not sense the camera because it is too sensitive, thereby reducing the alarm phenomenon caused by such reasons on the PCB board.

3. Accuracy of program retrieval: When changing lines, call the corresponding program name, do not call the wrong program, and check whether the through button is turned on to prevent the PCB circuit board from being mismeasured or missed.

What are the consequences of improper maintenance of SMT SPI?

1. Affecting production efficiency and product quality: SPI equipment is a key link in quality control in SMT patch processing. If it is not properly maintained, it may cause frequent equipment failures and affect production progress. In addition, inaccurate solder paste detection will cause defective products to flow into the next process, increasing the time cost of rework and re-entry into production.

2. Increase production costs: Improper maintenance may cause equipment to need frequent repairs, thereby increasing repair costs. In addition, when defective products are discovered in the later manufacturing stage, they may require longer rework work, increasing production costs.

3. Reduce product reliability: The main function of SPI equipment is to intercept poor solder paste printing at the source and reduce the production of defective products. If it is not properly maintained, it may lead to more defective products flowing out and reduce the reliability of the product.
