Abstract
PURPOSE: To prevent the thrusting-up bar of a device of performing mounting of semiconductor chips automatically from contacting its ring frame or mounting mechanism and from being thereby damaged by providing a magnetical detector to said thrusting-up bar.
CONSTITUTION: The semiconductor chip 21 provided on a sheet 22 is thrusted up with a thrusting-up bar 26 from the underside of the sheet 22 and is sucked up by a suction collet 20 guided to the upper side of the sheet 22, by which it is secured in the specified position of a lead frame. In this mechanism, a magnetical detector 27 is provided to the thrusting-up bar 26 and detects that the thrusting-up bar 26 has approached to a sheet holder 23 and other mechanism, thereby preventing the sheet holder 23, etc. from contacting the thrusting-up bar 26.
