An intelligent soldering cartridge that includes: a housing; a solder tip; a heater for heating the solder tip; a storage device for storing information about characteristics of the cartridge; a processor for retrieving the information about characteristics of the cartridge, monitoring the power level delivered to the solder tip to detect liquidus occurrence at a solder joint, determining a thickness of an intermetallic compound (IMC) of the solder joint using some of the retrieved information, determining whether the thickness of the IMC is within a predetermined range, and generating an indication signal indicating that a reliable solder joint connection is formed when the thickness of the IMC is within the predetermined range; and an interface for transmitting the indication signal.

The invention is directed to designs for heater-sensor sub-assemblies for soldering cartridges and de-soldering cartridges for soldering systems. The designs provide a high thermal capacity and accurate tip temperature sensing and control features. The coil portion of the heater assembly is spaced proximally from the distal end of the subassembly to segregate the coil from the thermocouple temperature sensor. The solder cartridges include connector wires of dissimilar sizes and materials to couple the heater coil wire to the connections of a handle and the soldering station to reduce heat conduction to the handle.

A soldering tool may include a tip portion and a tool body. The tool body may include a handle and the tip portion may be operably coupled to the tool body at a flange that separates the handle from the tip portion. The tip portion may include a tip that is heated to melt solder. The flange may include an end face and a light ring disposed at the end face. The light ring may be configured to direct light toward the tip.

A combustion tool with a detachable heating unit includes: a main body having an insertion pipe, an outer circumferential surface of the insertion pipe is axially formed with at least one insertion having a wedge locking tenon disposed therein; and an unlocking mechanism including a push button, the push button has a block sheet abutting against an elastic member, the block sheet compresses the elastic member, and the push button is automatically recovered to an original position through the elastic member; and a heating unit including a fasten ring and a heating pipe, an elastic support arm is axially protruded from the fasten ring, one free end of the elastic support arm is disposed with a locking hook inserted in the at least one insertion slot and moved along a the wedge locking tenon to form a locking or an unlocking status.

A brazing apparatus to join a first component and a second component includes a heating element configured to melt a ring located at a joint between the first component and the second component, and a probe configured to contact the ring. A position of the probe is biased toward the ring. The probe is installed at a probe support. The probe is movable along a probe central axis relative to the probe support. A sensor is operably connected to the probe and is configured to determine movement of the probe along the probe central axis. The movement of the probe is indicative of melting of the ring.

A soldering tip for a soldering apparatus and a method of forming a soldering tip for a soldering apparatus, the tip comprising: a body formed of a first material; a proximal end for attaching the tip to the selective soldering apparatus; and a distal end, the distal end having an outer surface, at least a region of which is formed from a second material, different to the first, the second material exhibiting greater solder wettability characteristics than the first material. The first material is preferably titanium or a titanium alloy and the region is preferably formed on the first material by first using a physical vapour deposition (PVD) process to create a first coating on at least a first part of the first material, which first part underlies the region, and then coating at least a part of that first coating with the second material.
