Abstract (en)

[origin: WO9707542A1] A method of making low and high mass assemblies at surface mount profile conditions utilizing a solder paste have a binder comprised of a thermosetting resin and cross-linking agent that also acts as a flux is described. The method of selecting the components and specific binders, including binders with a catalyst such as tin octoate are also described. The binder utilized has a gel point that is at or above the melting point of the solder powder and most preferably above such melting point.
