Abstract

1357066 Unjointing; soldering INTERNATIONAL BUSINESS MACHINES CORP 19 May 1972 [29 June 1971] 23564/72 Headings B3V and B3R An element bonded to a base is released from the base by ultrasonic vibrations. Soldered connections may be released by the method. As applied to releasing a ground rail 10, Fig. 1, from a circuit board 11, the rail is clamped by screws 14 to a fixture 13 which is attached by a horn 15 to an ultrasonic transducer 16. Springs 17 apply pressure between the fixture and circuit board while the transducer is swept through a range of frequencies or tuned to the resonant frequency, the vibrations being effected to soften the solder and release the connection. If desired, heat may be applied in the region of the bond, or the fixture may be heated or preheated. Axial, lateral or rotary vibrations may be used. A pin may be detached from a circuit board using a connecting socket clamped to the pin by a screw (22), Fig. 2 (not shown). The process may be used to detach a circuit module (Fig. 3).
