Testing and Inspection

Testing and Inspection

At Sierra Assembly, we understand that customers require their circuit board assemblies to be durable. The performance of a circuit board can only be long-lasting when regular maintenance, repair, and rework is performed.  

At Sierra Assembly, we understand that customers require their circuit board assemblies to be durable. The performance of a circuit board can only be long-lasting when regular maintenance, repair, and rework is performed. We at Sierra Assembly provide end-to-end testing and inspection services to support the assemblies we provide to our clients.

PCB Assembly Testing and Inspection at Sierra Assembly

We perform testing and inspection procedures early on during the assembly process. This allows us to detect defects early on, and ensure a finished high quality product. What sets us apart from other PCB assembly service providers is that we employ multiple testing and inspection procedures to ensure that the quality of our PCB assemblies is of the highest level. By ensuring thorough inspection, we can reduce the number of rework sessions. However, we also provide rework services for clients who wish to modify their current PCBs.

Nordson/Yestech Benchtop Automated Optical Inspection System for (AOI)- Model-BX AOI

  • Its features include:
  • 5 megapixel color imaging
  • 1 top-down & 4 side angle cameras
  • Quick set-up
  • High speed
  • High defect coverage
  • Low false failure rate

Nordson YESTECH's advanced 5 megapixel color camera imaging technology offers benchtop PCB inspection with exceptional defect coverage. This benchtop system inspects solder joints and verifies correct part assembly enabling users to improve quality and increase throughput. The optional four side viewing cameras add additional inspection capabilities found only on in-line systems.

Programming the BX is fast and intuitive. Operators typically take less than 30 minutes to create a complete inspection program including solder inspection. The BX utilizes a standard package library to simplify training and ensure program portability across manufacturing lines. Programs created with the BX are also compatible with Nordson YESTECH's complete line of AOI systems.

Advanced Fusion Lighting™ and newly available 5 megapixel image processing technology integrates several techniques, including color inspection, normalized correlation and rule-based algorithms, to provide complete inspection coverage with an extremely low false failure rate.

The BX is equally effective for paste, pre / post-reflow and even final assembly inspection. Remote programming maximizes machine utilization and real-time SPC monitoring provides a valuable yield enhancement solution.
