发明名称 PRODUCTION METHOD OF SOLDER CIRCUIT BOARD
摘要 A method for producing a solder circuit board includes the steps of imparting tackiness to a surface of an electrically conductive circuit electrode on a printed-wiring board to form a tacky part, causing only one solder particle to adhere to the tacky part, and heating the printed-wiring board, thereby melting the solder particle to form a bump part which corresponds to the tacky part and to which an electronic part is to be connected and forming a solder circuit.
