次に、第2実施形態の装着順序検査装置7Aについて、図14を参考にして、第1実施形態の装着順序決定装置7と異なる点を主に説明する。装着順序検査装置7Aは、部品装着機1または部品装着ラインを用いた装着作業に先んじて、複数の部品に予め設定された装着順序を検査する。図14は、第2実施形態の装着順序検査装置7Aの機能構成を示すブロック図である。
次に、第3実施形態の装着順序決定装置7Bについて、図15~図17を参考にして、第1および第2実施形態と異なる点を主に説明する。第3実施形態の装着順序決定装置7Bは、近接装着部品種群を対象とする。図15は、近接装着部品種群を模式的に説明するC基板種の基板KCの側面図である。図15の例で、小形チップ部品PB、チップ部品PC、およびメモリ部品PDは、近接装着部品種群を構成する。
次に、第4実施形態の装着順序決定装置7Cについて、図9、図17、図18を参考にして、第1~第3実施形態と異なる点を主に説明する。第4実施形態において、部品装着機1は、A基板種の基板KA、B基板種の基板KB、およびC基板種の基板KCを切り替えて生産する。基板種の切り替え時には、適宜段取り替え作業が行われる。A基板種およびB基板種は、多重装着が有る第一群の基板種に含まれる。また、C基板種は、近接装着が有る第二群の基板種に含まれる。第4実施形態の装着順序決定装置7Cは、第一群および第二群の基板種に対して、階層情報を使い分ける。
