Abstract:
The present invention provides a solder paste free of reducing agents and activators, and a method for producing a soldered product in which the solder paste is used to achieve solder bonding. The solder paste for reducing gas of the present invention is a solder paste for reducing gas used together a reducing gas. The solder paste contains a solder powder; a thixotropic agent that is solid at normal temperature; and a solvent, and is free of reducing agents for removal of oxide films and free of activators for improvement of reducibility.

Claim (Index 2):
A solder paste for a reducing gas used together with a reducing gas, essentially consisting of:\n a solder powder; a thixotropic agent that is solid at normal temperature; and a solvent; wherein the solder paste is free of reducing agents for removal of oxide films and free of activators for improvement of reducibility, wherein the thixotropic agent is a thixotropic agent that satisfies a wet-spreading area rate of 0 to 50% in the following procedures (1) to (5), (1) Applying a paste obtained by removing the solder powder from a solder paste consisting of a solder powder, a thixotropic agent and a solvent to a thickness of 100 \u03bcm (metal mask thickness) in a 5\u00d75 mm sized region on a nickel-plated copper substrate (20\u00d720 mm, thickness 2 mm); (2) Measuring the area of the paste one minute after the application; (3) Placing the copper substrate on a hot plate at normal temperature and heating the copper substrate until the copper substrate reaches a predetermined temperature; (4) Removing the copper substrate from the hot plate when the predetermined temperature is reached and cooling the copper substrate; and (5) Measuring the area of the paste on the copper substrate after cooling; where the predetermined temperature in the procedure (3) is a melting point of the thixotropic agent under normal pressure, and wherein the solvent shows a weight loss of 25% or more at a rate of temperature increase of 10\u00b0 C./min in thermogravimetry (TG) under normal pressure at 180\u00b0 C.
