Systems and methods for applying solder to a pin. The methods comprising: disposing a given amount of solder on a non-wetable surface of a planar substrate; aligning the pin with the solder disposed on the non-wetable surface of the planar substrate; inserting the pin in the solder; and/or performing a reflow process to cause the solder to transfer from the planar substrate to the pin.

A method is disclosed for manufacturing a substrate soldered by a solder agent, which contains solder and a contained material that can be boiled at a temperature below a melting temperature of the solder. The method includes: setting the substrate onto a heat generation body heated to a first predetermined temperature, which is lower than a boiling point of the contained material and higher than an ordinary temperature; increasing a temperature of the substrate, which is set on the heat generation body, to a second predetermined temperature, which is lower than the melting temperature of the solder and is a reduction-enabling temperature, to reduce an oxide on the substrate by a reducing agent; and, after reduction, heating the substrate to a third predetermined temperature, which is equal to or higher than the melting temperature of the solder, to melt the solder. A soldering device includes a heating section, a chamber, a reducing agent supply section, and a controller configured to control a temperature of the heating section and supply of the reducing agent into the chamber to execute the above-described manufacturing method.

A method of applying a braze component to a honeycomb structure may comprise: applying at least a partial vacuum within a chamber, the chamber defined at least partially by a vacuum device and a cover, the honeycomb structure disposed within the chamber, the braze component disposed between the honeycomb structure and the cover; pulling the cover towards the braze component in response to applying the partial vacuum; and pulling the braze component into a plurality of hexagonal cells defined by the honeycomb structure in response to pulling the cover towards the braze component.

A method of using a processing oven may include disposing at least one substrate in a chamber of the oven and activating a lamp assembly disposed above them to increase their temperature to a first temperature. A chemical vapor may be admitted into the chamber above the at least one substrate and an inert gas may be admitted into the chamber below the at least one substrate. The temperature of the at least one substrate may then be increased to a second temperature higher than the first temperature and then cooled down.

A solder joint, for bonding an electrode of a circuit board to an electrode of an electronic component, that includes: an Sn—Bi-based solder deposited on the electrode of the circuit board; and a solder alloy deposited on the electrode of the electronic component. The Sn—Bi-based solder alloy has a lower melting point than the solder alloy deposited on the electrode of the electronic component. Fine Bi phases in the solder joint each have an area of less than or equal to 0.5 μm.sup.2. Coarse Bi phases in the solder joint each have an area of greater than 0.5 μm.sup.2 and less than or equal to 5 μm.sup.2. A proportion of the fine Bi phases among the fine Bi phases and the coarse Bi phases is greater than or equal to 60%.

A capacitor (2) includes a capacitor main body (4), a base (6), and a resin layer (8-1). The capacitor main body includes an outer package case (10), an opening sealing member (14) attached to an opening of the outer package case, and a terminal lead (16-1, 16-2) extending through the opening sealing member. The base is disposed toward the opening sealing member of the capacitor main body and includes an insertion through hole (18-1, 18-2) into which the terminal lead is inserted to be exposed on a mounting surface side, and a protruding portion (20) surrounding the insertion through hole. The resin layer is arranged at least between the base and the opening sealing member. The base and the resin layer are in contact with or spaced apart from each other without at least partly adhering to each other.
