Abstract

PURPOSE: To perform positioning with image formation on the screen, by overlapping the incident lights from the components and the circuit board through the use of mirror and half mirror.
CONSTITUTION: The back image of components 2 incident from the lens 12 is reflected at the mirror 8, it is reflected on the half mirror 7 and mirror 10 via the lenses 14 and 16, and is projected on the screen 4 with magnification by the lens 18. The image of the bonding pad 3 on the circuit board 1 is reflected with the mirror 9, further reflected with the mirror 11 via the lenses 15 and 17, passes through the half mirror 7, reflected on the mirror 10 and is projected on the screen via the lens 18. The worker observes the screen 4 and positions component leads at the center on the pad 3 on the circuit board 1. With this method, fatigue by the worker is less and the components can correctly be positioned.
