BEI Electronics–The Pemtron TROI 7700HL 3D Solder Paste Inspection (SPI)

BEI Electronics is excited to announce the latest addition to our EMS equipment capabilities, the Pemtron TROI 7700HL 3D Solder Paste Inspection (SPI).  This addition is part of our drive to continually improve the overall quality of our products, enhance our customer’s experience with BEI, improve the efficiencies of our processes and drive out the unnecessary repair and inspection costs.

The electronics manufacturing industry has recognized and documented that 70% – 80% of all manufacturing defects in SMT can be attributed and traced back to the solder paste printing process. Visual inspection and/or Automated Optical Inspection (AOI) have often served as the detection point for capturing these defects, but we all know that this inspection is often too late in the process and drives up internal cost. The foundation of your surface mount assemblies start with, and require, a repeatable and reproducible solder paste application process.

To ensure that we are getting excellent solder paste deposits throughout the production order, BEI uses the SPI technology to provide our Engineers and Manufacturing personnel with measurements and feedback on how the solder paste process is performing.  We can verify solder paste volume and height as well as x/y accuracy on the pads.  This inspection review reduces the downstream rework, the material scrap and cost, and the unnecessary inspections while improving the overall product yields, our production efficiency, and the quality of our solder joints.

Other benefits include solder paste verification and validation testing of new chemistries and optimizing the print parameters of the printer itself.  SPC feedback is used to identify subtle tooling wear and slight changes to setups and environmental influences.

As technology continues to evolve, the components and their solder land areas become smaller, tighter, and are less forgiving which requires a greater emphasis on the process control and great defect detection.  At BEI, we use our SPI machine to help prevent the defects from occurring. BEI can ensure we have a great foundation on your products!
