Patent ID: 7440812

Claim:
A method for monitoring a mounting tact of a component mounting apparatus, the component mounting apparatus comprising a component supplier for supplying a component and a component holder for holding and mounting the component supplied from the component supplier onto a circuit board, the mounting tact being a time required by the component holder to mount a supplied component on the circuit board, the method comprising: collecting and monitoring a mounting tact result value of the component mounting apparatus during a mounting operation, via a communication system; calculating a tact loss which is an amount of the tact that exceeds a standard mounting tact, the tact loss corresponding to a mounting tact actual value and a standard mounting tact, wherein the mounting tact actual value is an actual value of the mounting tact and the standard mounting tact is a time required by the component mounting apparatus to mount the component on the circuit board in accordance with a specification of the component mounting apparatus without any tact loss; and monitoring the calculated tact loss.
