Abstract:
A solder alloy substantially consists of tin, silver, indium, bismuth, and antimony. With respect to the total amount of the solder alloy, the content ratio of the silver is 2.8 mass% or more and 4 mass% or less; the content ratio of the indium is 6.2 mass% or more and 9.0 mass% or less; the content ratio of the bismuth is 0.7 mass% or more and 5.0 mass% or less; the content ratio of the antimony is 0.3 mass% or more and 5.0 mass% or less; and the content ratio of the tin is the remaining ratio and the value of A in the discriminant (1) is 4.36 or less. A = 0.87 × In content ratio mass % ˆ’ 0.41 × Ag content ratio mass % ˆ’ 0.82 × Sb content ratio mass %
Abstract:
A lead-free solder material is provided, which shows a high thermal fatigue resistance and is able to effectively reduce occurrence of connection failure that would cause a function of a product to stop. A solder material comprises 1.0-4.0% by weight of Ag, 4.0-6.0% by weight of In, 0.1-1.0% by weight of Bi, 1% by weight or less (excluding 0% by weight) of a sum of one or more elements selected from the group consisting of Cu, Ni, Co, Fe and Sb, and a remainder of Sn. When a copper-containing electrode part (3a) of an electronic component (3) is connected to a copper-containing electrode land (1a) of a substrate (1) by using this solder material, a part (5b) having an excellent stress relaxation property can be formed in the solder-connecting part and a Cu-Sn intermetallic compound (5a) can be rapidly grown from the electrode land (1a) and the electrode part (3a) to form a strong blocking structure. Thus, even in a severe temperature environment, cleavage can be prevented from generating and extending, a high thermal fatigue resistance can be attained, and occurrence of connection failure can be reduced.
Abstract:
The present disclosure discloses a battery connection sheet, including: a first part, including a first metal sheet, a first buffer portion and a first connection portion, and a second part, including a second metal sheet connected with the first connection portion via electromagnetic pulse welding.
Abstract:
Es wird ein Verfahren zur Herstellung eines Rohres (11) aus Metall angegeben, mit welchem ein Metallband (2) mittels einer Abzugseinrichtung in seiner Längsrichtung bewegt und durh eine Formung (in 5) seinrichtung geführt wird, in welcher dassebe zu einem Schlitzrohr (6) mit einem in Längsrichtung verlaufenden Schlitz geformt wird. Die beiden Kanten des Metallbands (2) liegen am Schlitz aneinander. Sie werden zur Herstellung eines rundum geschlossenen Rohres (11) durch eine mit einem Laser ausgerüstete Schweißeinrichtung (10) miteinander verschweißt. Das Schlitzrohr (6) wird nach dem Austritt aus der Formungseinrichtung (5) zunächst bis in den Bereich des lasers bewegt und dann angehalten. Daraufhin werden die Bereiche der miteinander zu verschweißenden Kanten des Schlitzrohrs (6) durch den Laser vorbehandelt. Danach wird die Leistung des Lasers auf seine der Schweißtemperaturentsprechende Schweißleistung eingestelltund gleichzeitig wird das Schlitzrohr (6) durch Einschalten der Abzugseinrichtung in seiner Längsrichtung bewegt.
