PurposeThe purpose of this paper is to investigate the effects of H2 flow rate
on improving the solder wettability of oxidized‐copper with liquid lead‐free
solder (96.5Sn‐3Ag‐0.5Cu) by Ar‐H2 plasmas. The aim was to improve the solder
wettability of oxidized copper from 0 per cent wetting of copper oxidized in air
at 260oC for 1 hour to 100 per cent wetting of oxidized‐copper modified by Ar‐H2

PurposeThe purpose of this paper is to determine: how much the residual
curvature could be formed in sintered nano‐silver assembly when it is cooled to
room temperature from the sintering temperature (normally 275°C); how the cyclic
temperature load affects the residual curvature or stresses in sintered joint.
Then the stress level and the reliability of sintered nano‐silver for
high‐temperature a... hiện toàn bộ
