Spring Probe AOI Machine

A world-first AOI machine for the subject test item by leveraging AIOT as enabling technology, together MegAAOI's AOI peculiar line scan module for image capturing of the spring probes. Currently, it takes one inspector around 2 hours to inspect a 5cmx5cm test socket with 6000 probes. And wish to have a AOI machine to do the inspection automatically. The inspection requirement stemmed from the customer includes two folds as: 1) measurement for probes wear out, and 2) inspection of damage and debris. As proposed by MegAAOI, we plan to inspect both defects by using DL CNN to replace laser measurement and rule base AOI nowadays. The project started from collect defect and OK sample probes provided by customer, which include 4 pins and 9 pins probles with various dimensions. MegAAOI further to perform image capturing by using our AOI peculiar line scanner and to perform required customization. Having successfully capture image that can be used for AI DL CNN, we then enter the AI training cycle of initial AI model training, testing, data cleaning, retraining. The business value that we can deliver by our AOI machine is 20 sockets per hour by comparing with manual inspection of 2 hours per socket, which is 40 times faster then current human inspection.
