Printed-board supporting device, electric-component mounting system, and process of manufacturing printed-circuit board

摘要

A printed-board holding device for holding a printed board in a work system in which the printed board and a working head are moved relative to each other in a direction parallel with a top surface of the printed board so that the working head executes a desired operation in each of a plurality of predetermined portions of the top surface of the printed board. The printed-board holding device includes (a) a supporting member which is to be brought into contact with a central portion of a bottom surface of the printed board and is capable of supporting the central portion, and (b) a pressing member which is to be brought into contact with a central portion of the top surface and is capable of forcing the printed board toward the supporting member.
