PROBLEM TO BE SOLVED: To securely complete soldering. SOLUTION: This device has a solder storing means, a circuit board carrying means which carries a circuit board, and a jet means which jets molten solder. The jet means has 1st nozzle holes which are formed obliquely at a 1st angle to the horizontal surface and at a 2nd angle to the carrying direction of the circuit board, and 2nd nozzle holes which are formed obliquely at the 1st angle to the horizontal surface and at a 3rd angle different from the 2nd angle to the carrying direction of the circuit board. The molten solder can sufficiently be stuck on a land irrelevantly to the position of the circuit board where an electronic component is mounted, the size of the electronic component, etc. |
