<P>PROBLEM TO BE SOLVED: To make effective use of a time to wait for other operations to be completed to improve precision and reliability of a suction or mounting operation of a component to be mounted onto an electronic circuit board, thus improving yield and productivity. <P>SOLUTION: When mutual partial operations are done in parallel at least between two head units and waiting is done between these operations, a determinement is made as to whether either one of the parallel operations is completed earlier in steps S114 and S134 so that a waiting time comes about. When this waiting time is determined to occur, the operation speed is decreased on the part of the partial operation included in the parallel operation of the head unit at the side of this waiting time in step S118 or step S138, thereby delaying an operation within the bounds of this waiting time, the operation that can improve the precision or reliability of the suction or mounting. <P>COPYRIGHT: (C)2009,JPO&INPIT |
