Part 1: How JUTZE AOI Detects Defects

The JUTZE AOI machine uses advanced color-based detection to identify defects on printed circuit boards (PCBs). By analyzing the color of solder joints, the system can distinguish between good and defective components. For example, deep blue or black solder joints indicate good quality, while red, red-white, or green joints signal defects like oxidation or improper soldering.

Follow these steps to set up defect detection:

1. Adjust the camera parameters for optimal image capture.
2. Set the lighting conditions to highlight solder joints.
3. Program the defect criteria in the JUTZE AOI software, focusing on color thresholds.

Part 2: Importing Pick and Place Coordinates

Importing pick and place coordinates into the JUTZE AOI involves converting CAD files into a compatible format. This ensures precise component placement during inspection. Here's how to do it:

1. Export the CAD coordinate file from your pick-and-place machine in .txt or .csv format.
2. Open the file in Excel and use delimiters to separate the data into columns (e.g., component numbers, X/Y coordinates).
3. Save the file as a plain text (.txt) file.
4. In the JUTZE AOI software, go to 'Edit' > 'Import CAD' and load the .txt file.
5. Specify the data columns and check alignment with the PCB image.

Part 4: Programming Resistors

Programming resistors in JUTZE AOI involves setting up detection algorithms to check for placement accuracy and soldering quality. This section provides a detailed guide on how to program resistors for inspection.

1. Access the resistor settings by double-clicking on a resistor in the software.
2. Select the component type and copy the component number to the library for simultaneous programming.
3. Create a standard reference image (template) for the resistor.
4. Set up detection algorithms for pad detection and offset checks using vectors.
5. Adjust the light source to enhance feature visibility and set parameters for allowable offsets.
