Why is Solder Paste Inspection Important?

Solder Paste Inspection

Solder Paste Inspection is mainly done to check the solder paste deposits in the Printed Circuit Board (PCB) manufacturing process. It is observed that most of the solder joint defects in a PCB assembly are because of improper solder paste printing. With the help of solder paste inspection (SPI), you can reduce the defects related to soldering by a considerable amount. This post will explain the significance of SPI process and how it is essential.

Importance of Solder Paste Inspection Process

Here are some of the key points of information, which prove the importance of SPI process:

  • Improves PCB Quality & Performance: This process makes use of advanced equipment for precise inspection. Angle cameras are used to take 3D pictures, which are very helpful in measuring the alignment and volume of the solder paste. This helps improve the yield, as well as the print quality. Furthermore, it helps improve the performance of the PCBs.
  • Advanced Equipment for Better Control & Monitoring: As said earlier, angle cameras are used, which produce clear 3D pictures. Unlike the traditional cameras, 3D cameras are capable of capturing the height of the solder paste printed. This facilitates precise measurement of the solder paste volume. Thus, with the help of SPI coupled with automated optical inspection, manufacturers can easily monitor and control the component placement and solder paste printing processes.
  • Helps Reduce Solder Errors: Important information about the printing process can be obtained by doing the solder paste inspection. It gives a clear idea about the causes of defects, thus allowing you to make the necessary changes and reduce the errors to a minimum.

All the points mentioned above make manufacturers implement the SPI process to manufacture high quality PCBs. The inspection process not only helps manufacture defect-free PCBs, but also saves significant costs. In addition to this, it also helps reduce the delivery time of the manufacturers. This explains the worth of solder paste inspection process. For an error-free solder, it is therefore, recommended to implement SPI.
