Abstract
A circuit board inspecting apparatus includes a rotary table having a mount surface, a rotary table support section, a suction device, a suction path having a first end connected to the suction device and a second end located at the mount surface, an adsorption mechanism that adsorbs the board onto the mount surface so that the suction device sucks in gas in the suction path, a flow rate detection section that detects a flow rate of gas flowing through a portion of the suction path, the portion located inside the rotary table support section, a flow rate determination section that determines whether the flow rate of the gas detected by the flow rate detection section is equal to or more than a predetermined value, a contactless detection section that detects a placement state of the board on the mount surface in a contactless manner, and an inspection section.
