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 6):
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 the temperature for reduction with the reducing gas, wherein the reducing gas is formic acid or hydrogen, 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.
