The invention relates to a pretreatment process for a brazing composition that comprises metallic particles with a granulometry in the order of the micrometer or nanometer, one or several binders and one or several solvents, said process comprising: a desolvation step of the brazing composition, so as to obtain a desolvated brazing composition, then a compacting step of the desolvated brazing composition so as to obtain a preform of metallic particles, said preform being able to be used for the sintering of an electronic, photonic, thermal or mechanical component onto a substrate, the brazing composition being represented either by a brazing paste, or by a suspension of metallic or metallic oxalate grains in suspension in a solvent.

The sinter-bonding composition contains sinterable particles containing an electroconductive metal. The average particle diameter of the sinterable particles is 2 μm or less and the proportion of the particles having a particle diameter of 100 nm or less in the sinterable particles is not less than 80% by mass. The sinter-bonding sheet (10) has an adhesive layer made from such a sinter-bonding composition. The dicing tape with a sinter-bonding sheet (X) has such a sinter-bonding sheet (10) and a dicing tape (20). The dicing tape (20) has a lamination structure containing a base material (21) and an adhesive layer (22), and the sinter-bonding sheet (10) is positioned on the adhesive layer (22) of the dicing tape (20).

A silver-copper cutting electrode assembly, and method of manufacture is provided with optimized attributes to allow for improved durability, integrity and manufacturability. An electrode has a silver tip portion which is brazed to a copper body portion where the silver portion and joint have a particular structural relationship.

A bonding and sealing material includes, as the essential ingredients, a solder powder, silver nanoparticles coated with a coating material and a solvent, and additionally includes at least one ingredient selected from the group consisting of selenium metal, oxide film inhibitors and oxide film removers. This bonding and sealing material can easily form under mild conditions a metallic adhesive layer having good hermetic sealability and UV resistance of the sort desired when sealing a short-wavelength light-emitting device such as a UV-LED, and can be stably used over a long period of time.

Methods disclosed herein include using additive manufacturing to create a joint between a first metallic material and a second metallic material that is different from the first metallic material, wherein the porosity of the joint is less than about 0.1 percent by volume measured according to ASTM B-962. The additive manufacturing can be performed such that no intermetallic brittle phase forms between the first metallic material and the second metallic material.

Shapeable guide wire devices and methods for their manufacture. Guide wire devices include an elongate shaft member having a shapeable distal end section that is formed from a linear pseudoelastic nickel-titanium (Ni—Ti) alloy that has linear pseudoelastic behavior without a phase transformation or onset of stress-induced martensite. Linear pseudoelastic Ni—Ti alloy, which is distinct from non-linear pseudoelastic (i.e., superelastic) Ni—Ti alloy, is highly durable, corrosion resistant, and has high stiffness. The shapeable distal end section is shapeable by a user to facilitate guiding the guide wire through tortuous anatomy. In addition, linear pseudoelastic Ni—Ti alloy is more durable tip material than other shapeable tip materials such as stainless steel.

A method of attaching an electrical connector to a glass substrate, includes the steps of positioning a connector over a glass substrate in an area for attaching the connector, and extruding a soldering material over the connector. Where the glazing includes a busbar on the glass substrate, the busbar may be arranged in the area for attaching the connector.

A conductive path can be formed using metal material coated with a layer that is controllably activated to release the metal material downhole in the wellbore. The conductive path can be used to communicate signals or power downhole in the wellbore.

The method manufactures a hermetic sealing lid member used for an electronic component housing package including an electronic component arrangement member on which an electronic component is arranged. The method includes forming a clad material in which a silver brazing layer that contains Ag and Cu and a first Fe layer arranged on the silver brazing layer and made of Fe or an Fe alloy are bonded to each other by roll-bonding a silver brazing plate that contains Ag and Cu and a first Fe plate made of Fe or an Fe alloy to each other and performing first heat treatment for diffusion annealing; softening the clad material by performing second heat treatment; and forming the hermetic sealing lid member in a box shape including a recess portion by bending the softened clad material.

Undercooled liquid metallic core-shell particles, whose core is stable against solidification at ambient conditions, i.e. under near ambient temperature and pressure conditions, are used to join or repair metallic non-particulate components. The undercooled-shell particles in the form of nano-size or micro-size particles comprise an undercooled stable liquid metallic core encapsulated inside an outer shell, which can comprise an oxide or other stabilizer shell typically formed in-situ on the undercooled liquid metallic core. The shell is ruptured to release the liquid phase core material to join or repair a component(s).
