What are the Top Reasons for 3D Solder Paste Inspection (SPI) to be used?

3-D Solder Paste Inspection is used for the detection of printer pads when it comes to offset, smearing, form, volume and more. However, the usefulness of 3-D SPI does not begin and end only with the spotting of defects. This system is able to achieve a lot more, and its usefulness goes beyond its primary functionality. Know about some of the main reasons why 3D Solder Paste Inspection System or SPI systems should be used.

Helps enhance process control

Over the last few years, a number of studies have been carried out that prove that as many as 70% of all issues in SMD solder joints can be tracked to the process of solder paste printing. Such errors in printing might result from an improper setup of printer, solder paste conditions, solder paste type, stencil type or design, stencil damage or various issues occurring together. With 3D Solder Paste Inspectionand installation, solder print problems can be prevented. Customers can also get the chance to make their own research on how the process control can be improved.

Prevents human errors

This system prevents false calls and human errors by the showing of image pairs of SPI – AOI defect. It also makes it possible to get better quality of products through additional showing of borderline flaws in SPI at the AOI verification station. Borderline issues, as a rule, do not lead to the best quality solder. SPI systems also offer direct process improvement and monitoring with respect to solder and paste print defects.

Reduces expenses of reworking

3D SPI also helps spot paste print defects. Electronic assemblies that never satisfy the specified criteria happen to be sorted after printing of the solder paste. 3-D SPI can help save the needless expenses of reworking electronic assemblies, especially in superior grade electronic products.
