— In this paper, we propose a new method for reducing assembly time in printed circuit board (PCB) assembly by prioritizing efficient simultaneous pickup operation of placement machines. Despite using the same placement machine, the efficiency of the schedule results in major different assembly time. Therefore, it is important to optimize the scheduling of(More)
In this paper, we propose a new method for reducing assembly time in printed circuit board (PCB) assembly by prioritizing efficient simultaneous pickup operation of placement machines. There are three major problems of the scheduling: (1) component feeder location (affects efficiency of pickup operation), (2) mounting sequencing (affects total distance of(More)

A highly integrated array processor (AAP2)-LSI has been developed. After the past 3 years study on the adaptive array processor 1 (AAP1), a challenging improvements on the SIMD's restraints are achieved by using the AAP2-LSI. The AAP2 array system makes it possible to carry out wideband modifiable operation (pseudo MIMD). Furthermore, each PE is capable of(More)
