Precision Micro Reveals Inspection For Tiny Etched Components
Precision Micro, a European photo chemical etching company, is offering 100 percent inspection on all parts as a result of investment in Automated Optical Inspection (AOI).
Utilising and modifying technology developed for the electronics manufacturing industry, Precision Micro has developed a bespoke AOI system. The system scans the work piece, acquires millions of data points (pixels) in a fraction of a second, and compares the data to a "˜first article, known good sample'.
As well as identifying missing components and features, the system measures critical dimensions and ensures results fall within agreed limits, with micron precision. The system can identify minute surface blemishes, scratches and stains. Any defects are highlighted immediately and all data is stored for future analysis.
In addition to ensuring the shipped product achieves six sigma quality standards, the results of the AOI are fed back into the company's continuous improvement programme, enabling appropriate remedial action to be taken.
As components become ever smaller, the limitations of manual visual inspection become increasingly evident. Presicion Micro says its AOI system is not only faster but far more repeatable than manual visual inspection could ever be.
The tool should also take subjectivity out of the equation which is always a problem with manual inspection, when a number of operators are asked to describe morphology.
The AOI system has been developed and installed in response to demands from major customers and is seen as a significant step in meeting the ever more stringent quality requirements of the aerospace automotive and healthcare industries.
