SYSTEMS, DEVICES AND METHODS RELATED TO CHARACTER RECOGNITION IN FABRICATION OF PACKAGED MODULES

Abstract:

A system can include a circuit board processing system configured to process a panel having an array of units, with each unit including a surface, and the panel including a surface. The system can further include a module processing system configured to produce packaged modules from the array of units, such that each packaged module includes a surface. The system can further include a character recognition system configured to obtain a digital image of a character imprinted on each of some or all of the surface of the panel, the surface of each unit, and the surface of each packaged module. The character recognition system can be further configured to perform a pattern matching process for the digital image of the character, with the pattern matching process including a principal component analysis to extract a principal characteristic, and linear and quadratic Bayesian discriminant functions to classify and find a correct character that corresponds to the principal characteristic.
