Application: PCB Board Online Testing Machine
Testing items and takt:
1. Foreign pollution
2. PCB oxidation
3. Missing and mistakes of characters
4. Whether size of the bore is beyond the tolerance.
Measurement takt: ≤3S
Automatic vision testing is based on the principle of optics. It uses various kinds of technologies like video analysis, computer, automatic control, etc. and makes detection and processing of electronic components and printing circuit characteristics. It is a new way to confirm manufacturing defects.
Products with fingerprints or hair due to poor job are NG products
Products with contamination more than 10% of the area on the solder surface are NG products
Products with green paint pollution less than 0.5cm outside the gold-plated area are OK products
Products with complete characters are OK products
Products with PCB oxidated into black spots are NG products
Products with bore oxidation area less than 10% are OK products
Products with oxidation or aberration on the Mark points are NG products
Products with bore diameter within the tolerance are OK products
Products with inconsistent upper and lower bore diameters are NG products
