Abstract

846,961. Ultrasonic wave couplings. MULLARD Ltd. Feb. 26, 1959 [Dec. 3, 1957], No. 37648/57. Class 40 (4). [Also in Group XXII] Printed circuits are soldered by a portion of molten solder locally raised from a bath with the aid of ultrasonic vibrations. A stainless steel bath 1, heated by electric elements 2, has its base formed by part of a coupling-member 4 secured to the bath at or about its nodal point and coupling a vibrating member 5, upstanding in the bath, to an electro-mechanical transducer 6. The transducer and coupler are enclosed in a housing 8 in which cooling liquid is circulated. In operation with the solder 3 in the bath molten the current supply to the winding 7 is switched on to vibrate the member 5 which results in a ridge of solder 20 and a printed circuit board 9 is transported over the ridge to solder the leads thereof to the circuit 19 on the underside of the board. The shape of member 5 is such that the ridge is confined to that part of the circuit to be treated. A number of circuit boards may be successively passed over the bath, the transducer supply being switched on each time one is to be soldered.
