Abstract

The soldering tool has ceramic elements 1...4 which are heated by electrical currents circulating in resistor wires 5. The tool is used, for example, to reflow solder in the process of making multiple electrical connections between leads 6, extending from edges of an integrated circuit chip 7, and contact lands 8 on circuit board 9. Ball-joint 10 enables block 11, to which elements 1...4 are attached to swivel in multiple directions from its normally level orientation relative to the stationary upper housing 12 of the tool. This adjusts the plane of tips 13 of elements 1...4 to conform to slight irregularities at the soldering surface of board 9. Symmetrically located springs 14 exert light biasing forces tending to keep block 11, and therefore the soldering tips, in a normally level orientation.
