Disclosed are a ceramic electric heating element having a two-layer structure, and an electric soldering iron. The electric heating element having a two-layer ceramic structure comprises an inner conducting layer and an outer insulating layer; the insulating layer wraps the conducting layer, and the conducting layer is exposed outside the insulating layer at the head and tail of the electric heating element. In addition, the ceramic electric heating element having a two-layer structure is used to the electric soldering iron. The present invention allows the miniaturization in the manufacture of ceramic electric heating bodies, with low production cost and low difficulty in respect of the process.

The disclosure includes a heat-staking device comprising a base, an upright arm coupled to the base, and a head vertically movable along the upright arm. In some embodiments, the head includes a main head unit, a quill coupled to the main head unit, an insulating tip holder coupled to the quill and configured to removably retain a thermal-installation tip, and a handle configured to cause vertical motion of the insulating tip holder. The quill may also include a soldering iron configured to heat the thermal-installation tip. In some embodiments, the heat-staking device is configured to swap out thermal-installation tips while the thermal-installation tips are still hot.

A soldering iron hand piece that may be used for both a soldering tip and a soldering cartridge, allowing the same hand piece to be used for both a soldering tip and a soldering cartridge.

A heating tool having a temperature sensor fixed within a tip of the heating tool with maximum heat conductivity to the temperature sensor.

A soldering tip fastening device includes a soldering device fastener configured for fastening the soldering tip fastening device on a soldering device, and a soldering tip fastener configured to fasten a soldering tip on a soldering device when the soldering tip fastening device is fastened to the soldering device. The soldering tip fastener and the soldering device fastener are associated with opposite ends of the soldering tip fastening device. The soldering tip fastening device has a sleeve with an elastic element, the sleeve being configured such that the elastic element is tensioned during the fastening of the soldering tip on the soldering device by the soldering tip fastening device.

A soldering tool may include a power unit including a controller, a tool body configured to interface with the power unit, and a tip portion operably coupled to the tool body. The tip portion may include a tip that is heated to melt solder by a heating element controlled by the controller. The tip is operably coupled to the heating element via a braze joint. The heating element may be operable at a first temperature range for melting the solder and a second temperature range, higher than the first temperature range, to facilitate forming or braking the braze joint.

The invention relates to a soldering tip assembly for an electric soldering device, in particular a soldering iron. The soldering tip assembly is designed to be releasably arranged on a soldering device handle which has a heating element, and the soldering tip assembly has a sleeve with a soldering tip provided on the distal end of the sleeve. The sleeve has an opening at the proximal end for introducing the heating element, wherein a holding element which at least partially surrounds the sleeve in an annular manner and a spring element which is provided between the holding element and the sleeve are provided, the spring element pushing the holding element in the distal direction. The sleeve has at least one stop arranged distally from the spring element. The stop secures the holding element against the soldering tip assembly in the distal direction.
