Abstract

PURPOSE:To enable highly accurate inner lead bonding efficiently at a high speed by independently providing an IC chip position detector for detecting an IC chip supplied and placed onto a receiving board and a detector for a lead position with respect to a head. CONSTITUTION:An IC chip 8' is picked up from an adhesive sheet on a wafer cassette ring 9 by a transfer arm 7, and the chip 8' is supplied and placed onto a receiver base 1 at an IC chip supply position. Then the position of the chip 8' is detected by a camera 11 exclusively used for the IC chip 8'. The position of lead group of carrier tape 5 which has reached the bonding position is at the same time detected by a camera 12 exclusively for detection of the lead group. Then the receiver base 1 which has completed the detection of IC chip 8' is moved in a Y direction while X, Y and theta compensation is made for matching with the lead group, and the carrier tape 65 is lowered to the bonding level by a tape holder 6 while the position of IC 8' is made to be the bonding position, and thereafter bonding is carried out through heating and pressurizing processes by a tool 3.
