Apparatus and method for mounting components on substrate

摘要

An apparatus has a holder that receives a component from a component supply and then places the component on a substrate. In operation, it is determined whether the holder makes an interference with another component mounted on the substrate. If the judgement is affirmative, an mounting of the component held by the holder is prohibited. If, on the other hand, the judgement is negative, the component held by the holder is mounted on the substrate.
