Electronic Components Scan  


Executive Summary

Optimet's ConoProbe MK10 with 25 mm and 50mm focal lenses was used to scan electronic components. The main industrial inspection application is related to the components roughness. Two types of objects were measured:
  • BGA components (three kinds )
  • Chip
The following parameters were measured for BGA components:
  • Width  of small metal balls
  • Height of small metal  balls
  • Distance between metal balls
  • Chip's height and roughness
Due to Optimet's technology we were able to measure bright golden chip's roughness and dark colored BGA components on the same scan with highly accurate results.  

1. Optimet's Advantages over Other Technologies:

1. Due to the ConoProbe sensor's capability to change laser's power and SNR filter, optimal methods of scanning are easily reached for both diffusive and reflective areas.

2. Unique collinear technology

3. Auto‐exposure feature enables measurements of bright and dark materials on the same scan

4. Capability to measure sharp angles in minimum clearance

5. High lateral resolution

6. High sampling rate with no need for averaging
