With the aim of evaluating the contamination level of materials for earlier defect detection, our partner SACMI development of a electronic olfactory system (electronic nose) capable of evaluating contamination through the detection of unwanted organic molecules in the air in the optoelectronic assemblies.

Figure 1 – electronic olfactory system

An array  of sensors  capable of detecting unpolymerized epoxy glue, used to fix the optical components in the assemblies, was  defined,  tested  and  implemented. The integration with the iQonic platform through remote data communication was then established and validated. This resulted in the prediction of the presence of defects in the opto-electronic assembly at early stage.
