Abstract

Current limitations of silver sintering are long processing times and high processing temperatures. To overcome these restrictions, different tin contents are added to the sintering paste. Various preheating times and processing times are evaluated at a processing temperature of 235°C. The positive effect of micro scale tin particles on shear strength and porosity at reduced process parameters is demonstrated. The addition of tin particles enables a reduction of both the processing temperature and time while maintaining high shear strengths. At a processing time of 60 s and no preheating time, the addition of 27.5 at% tin to the sintering paste leads to an increase in shear strength of 417 % from 4.6 MPa to 19.2 MPa, compared to the sintering paste without an alloying element. Energy-dispersive X-ray spectroscopy shows the homogeneous distribution of the alloying element in the joint that has been fabricated with the produced sintering paste. The porosity of the sintered layer is reduced by the addition of tin as alloying element which can improve the electrical and thermal properties as well.
