Optical tab-weld inspection targets visible burrs, displacement, surface burns and weld appearance. Internal lack of fusion, connection strength and resistance cannot be established from surface shape alone; suitable nondestructive, mechanical or electrical tests are needed.
How to validate
Define the welding process, copper or aluminium materials, inspection region and cycle time before assessing lighting, views and protection. Correlate appearance with process parameters and connection tests. These stations need separate engineering rather than assumed compatibility with standard PCBA AOI.
This is a general industrial-vision evaluation guide, not a delivered IRIS ANT PCBA AOI case study or a standard machine configuration. The station must be qualified for the parts, optics and automation requirements.
Project evaluation checklist
- Define the item, visible inspection surfaces and minimum defects; separate appearance, internal structure and electrical or functional checks.
- Prepare verified good, defective and borderline samples across lots; separate training and acceptance sets.
- Report escapes and false calls by defect class, with review workload, complete cycle time and repeatability.
- Confirm program versions, permissions, retention and traceability fields; approve production only after trials pass.
