Lead-free solder materialis mainly composed of tin (Sn), silver (Ag), and copper (Cu), known as SAC alloys. These materials can match the melting point, wettability, and mechanical strength of traditional leaded solder. For example, SAC305 (containing 96.5% tin, 3% silver, and 0.5% coppe...

Second, the reliability of lead-free solder joints Shear fatigue and creep cracks: solder joints in the shear force is easy to fatigue and creep, resulting in cracks. Electromigration: under the action of the current, the metal elements in the solder joints may occur ionic migration, affecting ...
there are still some outstanding issues in the process of lead-free, such as shear fatigue of solder joints, creep problems, false soldering phenomenon, etc., are to be further studied. At the same time, new reliability issues brought about by lead-free electronic assembly also need to be ...
Lead Free Solder Wire and Solder Paste are manufactured using different composition and ratio. But the most popular and widely used composition and ratio is SAC (Tin Silver Copper) in the Ratio 96.5% Tin + 3.0% Silver and 0.5% Copper....
flip-chip technology has been increasingly adopted in consumer electronics and high-performance products. During flip-chip packaging, lead-free solder paste can be used for substrate bumping, modules, and board level connections, etc. What kind of lead-free solder paste should be selected in practi...
2. Lead-Free Solder Lead-free solder generally has a higher melting point than conventional solder. ●Tin-antimony solder:Contains 95% tin and 5% antimony. This type of solder is lead-free and therefore safe for water supply lines. Designed for use in plumbing applications where frequent extrem...
The Reduction of Lead in Drinking Water Act was enacted on January 4, 2011 to amend Section 1417 of the Safe Drinking Water Act (SDWA or Act) respecting the use and introduction into commerce of lead pipes, plumbing fittings or fixtures, solder and flux. The Act established a prospective ef...
Why is Solder Flux Used in Soldering?The main function or use of flux in any Printed Circuit Board Assembly or rework is to clean and remove any oxide and impurities from the board. These oxides deposited on the board may not permit good solder joints. If the solder joint is poor, there...
