Abstract

Abstract A supporting shank attachable to a soldering iron and provided at its end with a pair of elongated tip bodies disposed in spaced parallel relation and extending transversely of the shank. The tip bodies are each provided with a longitudinally extending continuous groove for reception of a row of connector pins of an electrical component. The grooves are each of a depth less than the distance which the connector pins project from the underside of the printed circuit board on which the component is mounted and are of such width as to retain a quantity of solder in a molten state by capillary action when the tip is heated, so that all the connector pins may be simultaneously soldered to or desoldered from the printed circuit board. End portions of the tip bodies are pointed and wedge-shaped so that they may be used for straightening bent over connector pins by prying the latter away from the board.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 190 words
A soldering and desoldering tip for use in soldering and desoldering rows of connector pins of an electrical component from a circuit board upon which the component is mounted on one side of the board with the pins extending through rows of apertures in the board and projecting a substantial distance on the opposite side of the board, said tip comprising a supporting shank, means on one end of said shank for detachably connecting said shank to a heating source, at least one elongated tip body provided at the opposite end of said shank from said one end and extending transversely thereof, said tip body having a single outwardly oriented work engaging longitudinal portion including continuous uninterrupted fixed side walls providing a single continuous longitudinally extended groove which is open outwardly for reception of a row of connector pins, said groove being of such width that a quantity of solder in a molten state may be retained therein by capillary action when the tip is heated, said groove being of a depth which is less than the distance which the connector pins project from the underside of the circuit board.
Claim 2
Dependent Claim 190 words
A soldering and desoldering tip for use in soldering and desoldering rows of connector pins of an electrical component from a circuit board upon which the component is mounted on one side of the board with the pins extending through rows of apertures in the board and projecting a substantial distance on the opposite side of the board, said tip comprising a supporting shank, means on one end of said shank for detachably connecting said shank to a heating source, at least one elongated tip body provided at the opposite end of said shank from said one end and extending transversely thereof, said tip body having a single outwardly oriented work engaging longitudinal portion including continuous uninterrupted fixed side walls providing a single continuous longitudinally extended groove which is open outwardly for reception of a row of connector pins, said groove being of such width that a quantity of solder in a molten state may be retained therein by capillary action when the tip is heated, said groove being of a depth which is less than the distance which the connector pins project from the underside of the circuit board.
Claim 3
Dependent Claim 24 words
The device as defined in claim 1 which is further characterized in that said elongated tip body is of a substantially circular cross section.
Claim 4
Dependent Claim 29 words
The device as defined in claim 1 wherein at least one end portion of said elongated tip body is pointed, wedge-shaped and constitutes means for straightening bent-over connector pins.
Claim 5
Dependent Claim 59 words
The device as defined in claim 1 wherein said tip also includes a second elongated tip body extending transversely of the shank in spaced parallel relation to the first mentioned tip body, said second tip body including a second groove identical to the first and spaced therefrom a distance equal to the distance between two rows of connector pins.
Claim 6
Dependent Claim 27 words
The device as defined in claim 4 wherein said shank includes a bifurcated end portion carrying the respective first and second tip bodies on the furcations thereof.
