Abstract: Disclosed are a composition for brazing aluminum, and a method for brazing aluminum using the same. The composition for brazing aluminum may have excellent adhesion or bonding strength and improved corrosion resistance, for example, after bonding. The composition for brazing aluminum may include an amount of about 30 to 60 parts by weight of a zinc-based compound, and an amount of about 10 to 40 parts by weight of a metal titanium. For example, by using the composition for brazing aluminum in, base metals may be bonded by applying and heat treating the flux without addition of separate filler metal, thereby simplifying a bonding process and reducing a bonding time.

Abstract: Provided is an apparatus for performing a reflow process of a solder ball provided to a semiconductor chip. The reflow apparatus may include a coil, a support member and a moving member. The coil may receive a current from a power supply to heat the solder ball using an induced heating method. The support member may be disposed on the front or the rear of the coil and may support a printed circuit board on which a semiconductor chip is mounted. The moving member may move the printed circuit board so that the printed circuit object passes through an internal space surrounded by the coil.

Abstract: A heat transferring member comprises a heat transfer body for melting solder, and a pipe inserted into a hole formed in the heat transfer body, wherein heat from a heating member is conducted to the heat transfer body. The pipe includes a tubular-shaped substrate made of copper or copper alloy, and an aluminum oxide film formed at least on a peripheral surface of the tubular-shaped substrate. The pipe may be press-fitted in the hole.

Abstract: Aluminum parts, such as heat exchangers, with improved resistance towards corrosion caused by contact with stationary water or aqueous compositions can be obtained by addition of Li compounds to the flux used for brazing such parts. LiF and especially Li fluoroaluminates are very suitable. Another aspect of the invention concerns fluxes containing Li salts and their use for brazing of aluminum parts.

Abstract: The present invention generally relates to an automated solar cell electrical connection module that is positioned within an automated solar cell fabrication line and is configured to ensure a robust and reliable bond is formed during the electrical connection process. The electrical connection module generally provides a module and process for automatically attaching a junction box to a composite solar cell structure during the fabrication of a completed solar cell device. The electrical connection module further provides a thermode assembly including heating elements for forming a soldered connection between the junction box and the composite solar cell structure and a temperature sensing device in thermal communication with the heating elements for detecting a temperature profile during the connection process.

Abstract: A method of assembling aluminum alloy products, such as sheets, strips or tubes, by means of fluxless brazing, where the absence of flux is made possible by using a prior treatment resulting in formation of a conversion layer on the surface of the products. The treatment involves using a solution containing K+ and F? ions and at least one acid in a quantity such that the pH of the solution is less than 3. The inventive method enables effective flux was brazing in industrial conditions, such as a for the production of heat exchangers used in motor vehicles.

Abstract: Soldering paste for bonding an electronic component to electrodes on a ceramic substrate includes alcohol having at least two OH groups, organic acid, and metallic powder. The electronic component disposed on the electrodes through the soldering paste undergoes a reflow performed in a nitrogen atmosphere. Accordingly, an ester film is formed around the electrodes as a reaction product of the organic acid and the alcohol. The ester film incorporates therein the remaining organic acid and metal salt as its reaction product. As a result, high insulation reliability is provided.
