Mounting device, information processing device, and mounting method

A mounting method for use in a mounting device comprising:

• a mounting head, having a pickup member picking up a component, which moves and places the component at a placement position by picking up the component with the pickup member from a supply section having a holding member holding the component;
• an imaging section configured to image the component held by the mounting head;
• and
• the mounting method comprising:
• (a) a step of executing a first placement process in which the component is picked up by the mounting head, positional deviation is corrected based on imaging results of the component captured by the imaging section, and the component is placed at the placement position, and
• (b) a step of executing a second placement process in which the component is placed at the placement position by omitting the imaging process by the imaging section at the mounting head when the positional deviation is within a predetermined allowable range.
