The main technological objective of the GreenRoSE project is to provide European SMEs of the electronics sector with the knowledge and tools to produce electronic equipment free of hazardous substances, with defined quality and reliability. For the realization of the objectives the Advanced Interconnections Technology Laboratory for substitution technology assessment and quality tests has been set up in ITR, ISSP and Cynel. The main testing equipment of the Quality Laboratory in ITR is as follows: solderability testers, rotary dip tester, ionograph, sirometer, digital Viscometer, AOI, resistivity 4 point resistance meter, climatic chamber, stereoscopic and metallurgical microscopes, system for microstructures metallographic preparation of the samples, UV laser system, convection oven and double-wave soldering machine.



The range of investigations that can be carried out in ITR Quality Laboratory concerns: quality investigation of materials and components for assembly processes, quality evaluation of soldering technologies parameters, quality investigation of solder joints as well as climatic tests performance of soldering materials, PCBs and solder joints.



ITR has designed test boards for solderability measurements of PCBs with lead-free coating, characterisation of the immersion tin coating and estimation of solder joints quality produced in reflow and wave soldering processes.
