A solder paste inspection machine (SPI machine) measures the height, volume, and area of paste deposits. It also computes stencil offsets and finds defects in your PCBs. These machines are able to measure solder paste deposits accurately, which is critical to early detection of a defect found within the screen printing process of the PCB.
Why Is SPI Important?
When you are able to use an SPI machine to detect any possible defects in the solder paste application, you can catch mistakes early on in the process. This allows for adjustments to the printing process before your PCB is populated and the cost to repair has increased significantly. The machine needs to measure accurately not only the length and width, but also the height, volume, and area of the solder paste feature.
This machine can catch defects early in the process, and it can save time and money. The solder paste must be applied consistently and accurately, and it is critical to detect any problems as soon as possible. Having the ability to measure the three-dimensional aspects of the solder paste on the PCB allows you to find these issues early on so that you can make necessary changes to improve the functionality of the PCB, which will reduce your reworks and improve your profits.
