New choices for code readers installed on load ports

Conventional code readers have limited options and high costs

Various devices are required to ensure proper traceability of objects. One such device is a code reader. In recent years, we have seen various types for different applications such as compact models and two-dimensional code readers. However, there are limited choices for code readers that can be used for the load ports on semiconductor manufacturing equipment.
For these load ports, the code reader installation location is specified in SEMI standard E15.1. The specifications for this location make it very narrow with a lower height than the actual code it needs to read. Therefore, reading is not possible unless there is a compact code reader that is able to reliably read codes at an angle from below. There were very few conventional code readers able to do this.
