With substrate and substrate testing method

With substrate, comprising: a recognition camera that is movable with respect to a positioned substrate; performing a test execution unit that causes the recognition camera to recognize a component mounting position on the substrate, and an inspection process before component mounting which checks whether a component can be mounted in the component mounting position; and a unit for setting the operating mode for the renewed input, which enables the examination execution unit to a mode for re-input, wherein the test execution unit the inspection process before component mounting for all component mounting positions on which components are to be mounted, executes, when the mode for re-entry is not set by the operation of the unit for adjusting the operation mode for re-entry, first causes the recognition camera, to recognize the component mounting position, and then a process of checking the presence of a component, which checks whether the component is mounted in the component mounting position, executes, when the mode for re-entry by the ...
