BRAZING & SOLDERING TODAY particles of submicron size are completely miscible with the molten phase of the base silver-organic material, resulting in compact silver layers. This procedure leads to good adherence, especially to copper substrates. Shear strength in the order of 20–25 MPa was achieved, which is about the strength of a conventional Sn63Pb37 solder. The shear strength can be easily increased if a third component with a densifying effect is added. This silver solder material can be used as dry powder or as paste, and layer thicknesses can be achieved within a broad range.◆ References Note: Refs. 3–8 are from Brazing, High Temperature Brazing and Diffusion Bonding, LÖT-2013, DVS-Berichte, Vol. 293. 1.
