    摘要: The invention provides a solder-precipitating composition containing Sn-Pb alloy powder and an organic acid salt of Pb as essential components, and capable of precipitating solder as a result of substitution between Sn contained in the Sn-Pb alloy powder and Pb contained in the organic acid salt of Pb. Further, the invention provides a mounting method including the steps of supplying a conductor on a board with a solder-precipitating composition which contains Sn-Pb alloy powder and an organic acid salt of Pb as essential components, heating the solder-precipitating composition supplied on the conductor, to precipitate solder on the conductor and pre-coat the conductor with solder, as a result of substitution reaction between Sn in the Sn-Pb alloy powder and Pb ions in the organic acid salt of Pb, mounting a device on the solder pre-coated conductor, and melting the solder layer to securely mount the device on the conductor.
