How Does JUTZE AOI Machine Detect Defects?

Here is a summary of the video content:

    This tutorial video explains how the JUTZE AOI (automatic optical inspection) machine detects defective electronic components, such as resistors and capacitors, on printed circuit boards (PCBs). The presenter, who has over 10 years of experience in the AOI field, provides a detailed explanation of the process of identifying good and defective solder joints based on colour characteristics. Deep blue or black solder joints indicate good quality, while red, red-white, or green solder joints indicate defects, typically caused by oxidation or improper soldering (e.g., tilted resistors). The video emphasises the need to program AOI machines to recognise these colour-based characteristics, enabling them to distinguish between good and defective products. The video also mentions that while experienced users can identify defects at a glance, newcomers may need to learn how to input these parameters into the AOI system.

How to Import Pick and Place Coordinates into JUTZE AOI Machine

Here is a summary of the video content:

The video primarily explains the process of importing CAD coordinate files into AOI (automatic optical inspection) equipment. Key steps include:

1. File preparation: Export the CAD coordinate file from the pick-and-place machine in txt or csv format, containing data such as PCB board location numbers, component numbers, X/Y coordinates, angles, and puzzle numbers.

2. Excel processing: Open the text file in Excel and use a delimiter (such as a comma) to separate the data into columns, ensuring that the data is clearly separated. Typically, retain 5-6 key data columns (location numbers, component numbers, X/Y coordinates, angles, and puzzle numbers).

3. Save Format: Save as a plain text file (txt) without adding additional comments or description columns.

4. AOI Import:

- In the AOI software, select ‘Import CAD’ from the ‘Edit’ menu and load the saved txt file.

- Specify the data columns (e.g., the first column is the location number, the second column is the component number, etc.).

- Check the alignment of coordinates with the PCB image. If they do not match, adjust using horizontal mirroring or moving the window to ensure coordinates align with component positions.

5. Notes:

- Ensure at least two diagonal marker point coordinates are included.

- Note the conversion between PCB dimension units (micrometres) and CAD coordinate units (millimetres).

- Avoid manually entering spaces; copy spaces from the file to ensure proper formatting.
