Title:
WORK HOLDER OF SUBSTRATE
Document Type and Number:
Japanese Patent JPH04277700
Kind Code:
A
Abstract:
PURPOSE: To provide an all-purpose substrate work holder which is effective in screen printing and component mounting during the assembling process of a substrate, in a state wherein a plurality of printed circuit boards are left mounted. CONSTITUTION: A fixing jig 12 for a substrate work holder 10 has a hollow opening part, in which a substrate is placed; and jigs 26, 28, and 30 which apply a fixing force are between a couple of opening parts. The jigs which apply the fixing force have elliptic rotary bodies, which rotate to apply the force to the edge of the substrate, thereby strongly fixing it. At this time, the elliptic rotary bodies have the jigs which come into contact with only the edge of the substrate to apply the fixing force, and the printed circuit board and fixing jigs have smooth surfaces which are substantially in the same level.
