Title: Determining method for component array
Inventor: OKAMURA HIROSHI
IPC: H05K13/02
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To raise the production efficiency of a mounting line on the total basis by giving positions individually to uncommon components so that they may be arranged at corresponding positions for every board of each kind. SOLUTION: In a first process, a list of all components to be used is formed. In a second process, commonality of components among each board is investigated. In a third process, components are classified from the commonness. In a fourth process, components are separated into two mounters by fitting speeds. In a fifth process, the separated components are grouped from the fitting speeds and commonness. And in a sixth-a process, the arrangement of common components is determined on the basis of the priority order of the kinds of boards. In a sixth-b process, each group is arranged at a priority arrangement position in order according to the number of components to be fitted. In a seventh-a process, components to be used continuously among boards of different kinds are arranged preferentially.  In a seventh-b process, the arrangement of noncommon components whose production order is not continuous is alloted to arrangement positions vacant in the order of fitting. Accordingly, it becomes possible to raise the production efficiency by decreasing a kind switching loss of a mounter for printed boards of different kinds.
