Patent number: 8237091Abstract: A soldering iron (and a desoldering iron) with a replaceable tip, which is releasably securable on the forward heat-conducting end of a soldering (or desoldering) iron heat assembly. The tip has a tapered heat conducting core in a tip cap. The face of the core can have a depression for mating engagement with a protrusion of the heat-conducting end. Also, the face can lie in the rear plane of the tip cap. An assembly which allows for the easy removal and application of a replacement tip can include a sleeve with tightening bolt, a coil spring sleeve, or a slotted compressible sleeve. The tip can thus be replaced after it has worn out, and the heat assembly unit need not be replaced until it has burnt out. Methods of manufacturing and using the tip are also disclosed.Type: GrantFiled: May 25, 2005Date of Patent: August 7, 2012Assignee: Hakko CorporationInventors: Kayoko Yoshimura, Takashi Uetani, Takashi Nagase, Hiroyuki Masaki

Patent number: 7490751Abstract: A soldering iron tip having a copper or copper alloy core and a metal particle sintered member connected to the core to transfer heat therefrom to form a working soldering tip. The sintered member can be manufactured by powder metallurgy from a base material (iron, nickel and/or cobalt particles) and an additive (silicon, copper, silver, tin, boron and/or carbon particles) where needed. The sintered member can be formed as a cap which is fitted onto the working tip with a silver paste sandwiched therebetween, a brazing filler metal ring is positioned between an abutment shoulder and the cap, flux applied to the joint and the cap brazed into place. A metal, cermet or ceramic coating sprayed on the outer surface of the core, except for the (masked) working tip end, is not wettable by solder. An Ag—Al—Cu alloy coating layer in the rearwardly-disposed cavity improves heat conduction from the heater therein.Type: GrantFiled: February 24, 2004Date of Patent: February 17, 2009Assignee: Hakko CorporationInventors: Takashi Nagase, Takashi Uetani, Yoshimoto Teraoka, Takanori Naito, Norihisa Sekimori, Masayuki Miyabe

Publication number: 20050011876Abstract: A soldering iron (and a desoldering iron) with a replaceable tip cap are herein disclosed. The replaceable tip cap is fitted on the forward heat-conducting core end of a soldering (or desoldering) iron heat assembly. Conductive paste, powder or a low melting temperature material such as solder, can be sandwiched between the tip cap and the forward end to improve heat conductivity therebetween. An assembly which allows for the easy removal and application of a replacement tip cap can include a sleeve with tightening bolt, a coil spring sleeve, or a slotted compressible sleeve. The tip cap can thus be replaced after it has worn out, and the heat assembly unit need not be replaced until it has burnt out.Type: ApplicationFiled: May 26, 2004Publication date: January 20, 2005Inventors: Takashi Uetani, Takashi Nagase, Hiroyuki Masaki

Patent number: 6818862Abstract: In an iron tip for a soldering iron, composed of Fe plated copper or copper alloy, an outer surface excluding a solder coating portion in a leading end portion of the iron tip is plated with Cu in a film thickness range of approximately 10 to 50 &mgr;m, the surface is coated with a mixture of Al particles and flux, only the Al particles are melted in an inert gas atmosphere, and the surface is modified into a surface with a Cu—Al alloy coated layer having a high Al concentration. As a result, without using Cr plating, it is possible to provide an electric soldering iron having an excellent resistance to oxidation under high temperature environment and a high heat conductivity.Type: GrantFiled: October 4, 2002Date of Patent: November 16, 2004Assignee: Hakko CorporationInventors: Takashi Uetani, Mitsuhiko Miyazaki

Publication number: 20040141873Abstract: This invention provides solder that is substantially free of lead that minimizes corrosion from occurring in the soldering equipment such as the tip of the soldering iron and soldering dipping tank. Without substantial, if any, amount of lead in the solder, the solder does not expose lead into the environment. The solder composition also includes element(s) that extend the life of the soldering tip or other equipments associated with soldering. The solder composition may include Sn (tin) along with Co (cobalt) and Fe (iron). Tin may make up the most of the content in the solder composition. The two elements cobalt and iron substantially inhibit tin from corroding the iron, thereby substantially preventing the soldering iron tip and dipping solder tank from corroding. The composition of the solder may also include Ag (silver) to improve the mechanical strength and wettability of the solder.Type: ApplicationFiled: February 27, 2003Publication date: July 22, 2004Inventors: Tadashi Takemoto, Takashi Nagase, Takashi Uetani, Morio Yamazaki

Patent number: 6247631Abstract: A soldering iron device has a gas passage formed by enclosing a soldering iron tip 3 of an electric soldering iron with double pipes 6 and 7 to make a nozzle. By providing projections A, B and C in the spacing between said double pipes, the double pipes are prevented from any eccentricity and biasing, and the velocity of an inert gas G to be supplied is made slow to ensure that the gas is jet through the nozzle tip end. Further, engulfing of oxygen in the atmospheric air can be suppressed, whereby it is possible to prevent defective wetting of solder due to high temperature oxidation of the soldering iron tip and to suppress high temperature oxidation of workpieces and flux cored solder alloy and flux, and excellent solderability is obtained.Type: GrantFiled: January 10, 2000Date of Patent: June 19, 2001Assignee: Hakko CorporationInventors: Ichiro Kawakatsu, Takashi Uetani
