Develop vision test solution for monochrome LCD pattern recognition, Keypad characters, screws presence & orientation, etc.
Why?
To replace human inspection method which can subject to Quality error and Longer test time.
Having a Low cost Automated Inspection tester is a good alternative.
Our vision method is tested against required acceptance criteria (including Lighting) for consistent Quality.
With knowledgable software & mathematical modelling, test time can be greatly reduced compared to human eye. This enhances throughtput for our customer’s production.
Project Experiences
