ABSTRACT:
An arrangement for solder-coating respective end portions of elongated components in a molten solder bath includes a fixture to be loaded with the components. This fixture includes at least one supporting wall that is capable of maintaining the fixture afloat in a predetermined position on an upper surface of the molten solder bath even when the fixture is fully loaded. The supporting wall has at least one opening through which one of the end portions of a respective component passes into the molten solder bath to a depth necessary for the molten solder to coat the respective end portion to the desired extent when the fixture floats in its predetermined position on the molten solder bath. The fixture may be used in conjunction with a handling device which advantageously includes two pin-shaped projections that engage the fixture at two locations spaced from one another along a horizontal axis with freedom of movement of the fixture relative to the projections at least in the upward direction in that the projections are received in respective vertical slots of the fixture. These projections are then moved at least downwardly to an extent necessary at least to lower the fixture onto the upper surface of the molten bath and then to release the fixture for free floating on the upper surface of the molten solder bath.
