Electronic component mounting method and mounting apparatus

An electronic component mounting method for mounting a plurality of electronic components on a substrate by using a plurality of moving tables, said plurality of moving tables installed on a base, each moving table of said plurality of moving tables including a mounting head for picking up and transferring each electronic component;

• and a camera for recognizing said substrate,
• said mounting method comprising the steps of:
• (a) taking an image of a calibration substrate having a reference mark for position calibration by said camera, and obtaining position calibration data intrinsic to said each one of moving tables having the camera,
• (b) taking an image of a said substrate by only one of said cameras prior to mounting of said each one of electronic components, and recognizing a position of said substrate, and
• (c) picking up said each one of electronic components by said each one of mounting heads, and mounting the electronic component on said substrate,
• wherein said step of mounting each electronic component on the substrate induces a step of controlling the position of said moving table on the basis of said substrate position recognition result and said position calibration data, said position calibration data based on said calibration substrate having said reference mark and based on reference position recognition mark on said base.

An electronic component mounting apparatus comprising:

• (a) a base,
• (b) a first moving table and a second moving table installed on said base,
• wherein said first moving table and second moving table are movable on said base,
• said first moving table has a first mounting head and a first camera,
• said second moving table has a second mounting head and a second camera, and
• said first mounting head and said second mounting head have a function of picking up and transferring a plurality of electronic components,
• (c) a position calibration data acquisition unit for recognizing a position of said first moving table and said second moving table, and calibrating a position of said first moving table and said second moving table based on reference marks on a calibration substrate and based on reference position recognition mark on said base,
• (d) a position recognition unit for recognizing the position of a substrate mounted on said base,
• wherein said position recognition unit is recognized when taken by said first camera only,
• (e) a control unit for controlling the position of said first moving table and said second moving table on the basis of said position recognition unit and said position calibration data acquisition unit, and
• (f) a drive control unit for driving said first moving table, said second moving table, said first mounting head and said second mounting head.
