aSolder is a metal alloy that is used for making electrical connections.There are several types of solder with various applications.The most common type of solder consists of tin and lead with a rosin core.Some types of solder have an acid core.In electronic devices rosin-core solder should ...
A Pb-free solder alloy based on Sn as matrix is provided, which is a metal that has no toxicity and is environmental friendly. The Pb-free solder comprises a tetra-nary composition consisting essentially of about 99.0 weight % Sn, 0.3 to 0.4 weight % Ag, and 0.6 to 0.7 weight % Cu,...
Solder paste is able to pass cold-hot recycling test. However, adding too much silver (usually more than 4%), solder balls will become fragile instead. • Indium (In) Indium is possibly a type of metal that can be mixed with tin to become alloy metal with the lowest melting ...
申请(专利权)人: SENJU METAL INDUSTRY CO., LTD.发明人:K Tachibana,T Hattori 摘要: To provide a solder alloy in which the discoloration thereof is inhibited and a growth of oxide film is inhibited under a high temperature and high humidity environment, a solder ball, a chip solder, a ...
CONSTITUTION:The copper-tin-zinc alloy solder is made of the alloy solder for joining noble metals which consists, by weight, of 14 to 25% tin, 24 to 40% zinc, 5 to 10% tin, 5.1 to 10% gold, 1.0 to 5% palladium, 0.1 to 2% boron, and 0.1 to 1% phosphorus and consists of the...
Which is the Ideal Solder to Use? The choice of a solder alloy depends on several factors. However, the two major factors are: Subsequent thermal processes Solder melting point of the process A manufacturer may demand a high temperature solder since there will be subsequent thermal processes. Al...
A Pb-free solder alloy and a soldered bond using the same, in which the solder alloy has no harmful environmental effect but has a solderability comparable to that of the conventional Pb-Sn solder alloy. The solder alloy of the present invention either consists of Zn: 3.0 - 14.0 wt%, Al...
Gold is considered a noble metal and can be used in fluxless reflow environments. Pure gold has a melting point of 1,064°C but can be alloyed with tin (Sn), silicon (Si), or germanium (Ge) for lower melting points. 80Au/20Sn, a eutectic alloy is by far the most popular gold-...
Solder is a low melting point metal alloy (<450 °C), typically containing tin or indium, which is used to join two metal surfaces together (Bosco and Zok 2004, Chuang and Lee 2002a, b, Gale 2003, Goyal et al. 2003, 2004, Humpston et al. 1994, Kim et al. 2006, Lugscheider et...
Low-temperature solder refers to lead-free alloy solder with a melting point below 200 degrees Celsius, the most common being the SnBi/SnBiAg series of alloys. The melting point of this alloy is only 139 degrees Celsius, nearly 80 degrees Celsius lower than SAC305, which can effectively reduce...
