Circuit board processing system using local threshold value image analysis

A packaged module processing system comprising:

• a circuit board processing system configured to process a panel having an array of units that are joined together;
• a module processing system configured to produce a number of packaged modules from the array of units, such that each packaged module includes a surface;
• and
• a character recognition system configured to obtain a digital image of a character imprinted on a surface of the panel, the character recognition system being further configured to
• perform image analysis on the digital image of the character, the image analysis including applying a local threshold value to one or more localities of the digital image to provide a binarized image of the character, and
• classify the character based on the image analysis, the local threshold value applied to each locality of the one or more localities being based on pixel information around each respective locality.

A method for fabricating packaged modules, the method comprising:

• forming or providing a panel having an array of units that are joined together, each unit including a surface, the panel including a surface outside of the array of units;
• producing a number of packaged modules from the array of units, such that each packaged module includes a surface;
• and
• performing a character recognition process 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 process including performing image analysis including applying a local threshold value to one or more localities of the digital image to provide a binarized image of the character;
• and classifying the character based on the image analysis, the local threshold value applied to each locality of the one or more localities being based on pixel information around each respective locality.
