...Abstract Abstract Due to the recent requirement of higher integration density, solder joints are getting smaller in electronic product assemblies, which makes the joints more vulnerable to failure. Thus, the root-cause failure analysis for the solder joints becomes important to prevent failure...

...Abstract Abstract In a copper hot water system, a bent pipe was soldered into a straight pipe with twice the diameter. The neighborhood of the soldered joint was covered with corrosion product predominantly blue-green in color, presumably carbonates. When these corrosion products were scratched...

In 1935, the bend strength of steel coated with a lead-tin solder at 250 °C (480 °F) and with a bearing metal at 350 °C (660 °F) was determined ( Ref 24 ). Penetration of the liquid metals was observed on the tension side only of the bend...
