1. A method of component mounting for picking up components and mounting the same onto respective predetermined mounting positions of a circuit substrate by means of a plurality of nozzles connected to a single vacuum generating source, wherein the method including procedures for preventing occurrence of defective circuit substrates due to missing component, said procedures comprising steps of:

  • initializing achieved vacuum pressure of a nozzle after completion of component pick up operation to zero;

    detecting vacuum pressure decrease of the nozzle from the initialized zero value; and

    if the detected vacuum pressure decrease exceeds predetermined first threshold, making a judgment that the nozzle has failed to pick up a component, and skipping component mounting operation by that particular nozzle.
