SOLDER BAR
Kester makes no vague claims of outstanding solder purity. The quality of Kester Bar and Anode Solder is guaranteed by using virgin metals and strict quality control standards. Kester extrudes its bar and anode products to minimize oxidation, limit segregation and provide a denser grain structure than cast bar. Kester manufacturers solder to 5 distinct specifications. Each meets and exceeds requirements of QQ-S-571, ASTM 32, ANSI/J-STD-006, and JIS-Z-3282.
       
Kester Ultrapure® Solder Bar Kester Ultrapure® Low Dross Solder Bar Kester Ultrapure anode is available in 19mm and 25mm with a range of alloy combinations and in half of full spherical. Tarutin Kester Alloy 46
A fatigue resistant alloy designed to improved solder joint reliability for electrical and electronic applications requiring an alloy that meets the JIS-Z-3282 requirement. Comparing toSn63Pb37, Alloy 46 features better resistance in thermal cycling, withstands repeated mechanical stresses, high temperature creep, and strength against shock.
Made by a special process which controls the inclusion of oxides and metallic and non-metallic impurities, Kester Ultrapure is the industry standard bar solder for use in high tech electronics applications where lower surface tension and hole filling ability are essential . The purity of Kester Ultrapure far exceeds the requirements of QQ-S-571, ASTM B32, and ANSI/J-STD-006. Manufactured using the Ultrapure process and containing the same metal purity as Kester Ultrapure, Kester Ultrapure Low Dross is formulated with a special low dross additive which dramatically decreases dross formation on the solder pot. Lower dross formation decreases joint weakening inclusions in the solder loss through drossing. Tarutin Kester Peace Solder

Peace Solder is a Lead-Free solder alloy which was developed to keep equal reliability with existent eutectic solder systems.

 

 
  Kester Ultrapure® Solder Anodes Tarutin Kester Shinsolder Solder Analysis Program
  Kester Ultrapure Anode is made using the highest pure virgin metal. High pressure extrusion and the Ultrapure process assure all anodes with a dense fine grain structure. They permit higher current densities without passivation, guarantee uniform dissolution, and do not normally require bagging. A low dross alloy that meets and exceeds the JIS-Z-3282 requirements. This alloy is designed to reduce dross formation on the solder pot while providing good wetting. Shinsolder is available in solder bar and wire. Kester Solder Analysis Program is designed to effectively provide the control required for various soldering operations. By selecting the analysis options which best monitors in the solder composition, the quality of solder can be maintained. The recommendations are made on the basis of contamination levels reporting solder pot impurities.
