Abstract

Component mounting on opposite sides of a circuit board can be done with greater efficiency by holding the board vertically and automatically picking and attaching components for both sides simultaneously. 2 p. Referring to Fig. 1, circuit board 1 has component attachment lands 2 on opposite sides that have been pretinned with solder. Flux (Image Omitted) is applied over the solder. With the board supported in a vertical position, oscillating robot arms 3, one on each side, operate concurrently to pick components 4 from supply magazines 5 and attach the components to the selected lands by solder reflow. A diagram of the component gripping tool on each robot arm is shown in Fig. 2. Components 4 are held against the tool body 6 by vacuum supplied through channel 7 from a source.
