Solder wire dispenser, a portable hand-held device to apply solder accuratel and without touching the solder wire.

摘要

A hand-held device shaped as a pencil used for dispensing solder wire onto a soldering point. Such device contains a roll of solder wire that can be gradually extracted through a hole on the tip by pressing a button in forward motion to extract the solder without touching it. The device can be held in one hand and the dispensing of the solder wire is performed by an internal servo-mechanism that controls the amount of solder and the speed at which it is dispensed. The extracted solder can be pulled back into the device in order to retrieve small portions of the already extracted solder by pressing the same or a different button in backward motion in order to maintain a desired amount of solder outside the device. The device can be electrically powered by “AA” size batteries, or by an external power supply.
