SMD electronic assembly using Pb-free soldering technology

Krakow Division of ITE from few years is involved in activities connected with electronic assembly. The applied research is focused on SMD technology with implementation of Pb-free soldering alloys especially analysis of technological factors influencing on Pb-free solder joints quality, investigation of Sn-Ag-Cu alloy shear strength under influence of environmental conditions, choice of conformal coating lacquers for electronic devices operating in environment with increased humidity and others. Krakow Division cooperate with many SMEs (Small and Medium Enterprises) providing them technical support and assembling short series of electronic modules on request.
