A junction structure and a joining method of substrates are provided that stably can join the substrates and achieve high workability during joining. A second substrate 2 to be joined with solder to a first substrate 1 is bent with elasticity generated by a bending portion 9, and first joints 5 on the first substrate 1 and second joints 6 on the second substrate 2 are joined with solder in a state in which the first substrate 1 is brought into contact with, in a direction that increases the bending angle of the bending portion 9, a part where the joints 6 are formed on the second substrate 2.

An electronic component mounted structure has: a circuit board; two semiconductor elements that are mounted on the circuit board; and an AC coupling capacitor that is operable to cut off signals with a predetermined frequency or less and is provided between the two semiconductor elements. The AC coupling capacitor is mounted on the circuit board such that a part or a whole of the AC coupling capacitor is away from the surface of the circuit board.
Abstract:
Coupling reliability of a passive component is improved to increase the reliability of a semiconductor device. A first through hole is formed in a first electrode part of a first plate-like lead, and a second through hole is formed in a second electrode part of a second plate-like lead. As a result, at the first electrode part of the first plate-like lead, one external terminal of the passive component can be coupled to the first electrode parts on both sides of the first through hole while being laid across the first through hole. Also, at the second electrode part of the second plate-like lead, the other external terminal of the passive component can be coupled to the second electrode parts on both sides of the second through hole while being laid across the second through hole. Accordingly, at central portions both in the longitudinal and width directions of the passive component, the passive component is surrounded by sealing members. As a result, thermal stress applied to jointing materials such as solder can be reduced, improving the reliability of the semiconductor device (semiconductor package).

Abstract:
Systems and methods are provided for depositing solder in a first pattern over a first bonding pad on the substrate; depositing solder in a second pattern over a second bonding pad on the substrate, wherein the second pattern defines a larger area than the first pattern; placing the electronic device on the substrate such that pads on the electronic device are aligned with the first and second bonding pads; and reflowing the solder between the pads on the electronic device and the first and second bonding pads, causing the solder deposited on the first bonding pad to form a first solder joint and the solder deposited on the second bonding pad to form a second solder joint. The second solder joint is larger than the first solder joint causing the electronic device to be attached at an angle relative to the substrate.
