Abstract
An apparatus for mounting electronic components on the surface of printed boards by a suction head assembly 4 coupled to a head lift mechanism comprises a force sensor 6 for measuring the pressure exerted on the component by a mounting operation, and a microcomputer 1 for preparing a control signal in accordance with the deviation of the value measured by the force sensor from a desired value of pressure on the component. The rotation of a head lifting motor 51 is controlled based on the control signal.
