Abstract:
A multi-chip bonding method that uses:a substrate conveying device that conveys substrates, first and second substrate supplying and accommodating sections that are respectively disposed at both ends of said substrate conveying device, a bonding apparatus that bonds electronic components to said substrates conveyed by said substrate conveying device, and a holding device which holds a wafer ring or tray that has electronic components, and said method comprises at least the steps of: (i) holding a first wafer ring or tray which has electronic components of a first type that are to be bonded to said substrates by said holding device, (ii) successively feeding out substrates to said substrate conveying device from said first substrates supplying and accommodating section, (iii) successively bonding said electronic components of said first type on said holding device to all of bonding portions of said substrates to which electronic components of said first type are to be bonded, (iv) successively accommodating said substrates, on which said bonding of said electronic components of said first type has been completed, in said second substrate supplying and accommodating section, (v) exchanging, by way of using a wafer ring conveying device, said first wafer ring or tray held by said holding device for a second wafer ring or tray which has electronic components of a second type that are to be bonded to said substrates, and holding said second wafer ring or tray by said holding device, (vi) successively feeding out said substrates accommodated in said second substrate supplying and accommodating section to said substrate conveying device, (vii) successively bonding said electronic components of said second type on said holding device to all of said bonding portions on said substrates to which electronic components of said second type are to be bonded, and (viii) successively accommodating said substrates, on which said bonding of said electronic components of said second type has been completed, in said first substrate supplying and accommodating section.
