Abstract:
An electronic component is mounted on the mounting face of a printed wiring board and a plurality of terminals arranged on the mounting face of the printed wiring board are respectively bonded to a plurality of terminals arranged on the bottom surface of the electronic component by means of solder. Solder paste containing powdery solder and thermosetting resin is provided to the plurality of terminals on the mounting face, then the electronic component is mounted on the mounting face of the printed wiring board, and subsequently the solder paste is heated to bond the corresponding terminals by means of molten solder. Thereafter, the molten solder is allowed to solidify and the thermosetting resin separated from the solder paste is allowed to cure in a state where it is held in contact with metal members arranged separately relative to the terminals.

Claim (Index 1):
A method of manufacturing a printed circuit board involving mounting an electronic component on a mounting face carrying solder resist arranged thereon of a printed wiring board and bonding a plurality of first lands arranged on a bottom surface of the electronic component to a plurality of second lands arranged on the mounting face of the printed wiring board correspondingly to each other by means of solder, the method comprising:\n a providing step of providing solder paste containing powdery solder and thermosetting resin to the plurality of second lands; a mounting step of mounting the electronic component on the mounting face of the printed wiring board; a solder bonding step of melting the powdery solder by heating the solder paste to a temperature higher than the melting point of the powdery solder and respectively bonding the plurality of first lands to the corresponding plurality of second lands; and a resin curing step of curing the thermosetting resin separated from the solder paste, wherein at least one metal member is arranged around each at least one of the plurality of second lands, wherein the area in total of the at least one metal member is not greater than the area of the solder resist in a mounting region of the mounting face for mounting the electronic component thereon, and wherein the thermosetting resin cures in a state of being held in contact with the solder and the metal member.
