Kester Ultrapure Series Solder Bar Overview

The Kester Ultrapure Series Solder Bar is the industry standard for high-tech electronic applications where lower surface tension and hole filling ability are essential. Manufactured by a special process that controls the inclusions of oxides and metallic and non-metallic impurities, this solder bar ensures optimal performance and reduced defects.

High-Quality Solder Bar for Electronics

The Kester Ultrapure Series Solder Bar is designed for use in high-tech electronic applications where reliability and performance are crucial. With its lower surface tension and hole filling ability, this solder bar ensures strong bonds and minimizes the risk of defects and rework.

Meets International Standards

The Kester Ultrapure Series Solder Bar meets the requirements of IPC/J-STD-006C, ensuring compliance with international standards for high-tech electronic applications. This ensures that the solder bar is of the highest quality and suitable for use in demanding applications.

Storage and Handling

To ensure the quality and performance of the Kester Ultrapure Series Solder Bar, it is essential to store it in a dry, non-corrosive environment between 10 to 40 °C (50 to 104 °F). The surface may lose its shine and appear a dull shade of grey, but this is a surface phenomenon and does not affect product functionality.

Shelf Life and Availability

The Kester Ultrapure Series Solder Bar has a shelf life determined by the alloy used in the bar. For alloys containing more than 70% lead, the shelf life is 2 years from the date of manufacture, while other alloys have a shelf life of 3 years from the date of manufacture. Each bar is available individually, equal to 1-2/3 lbs, making it convenient to buy and use only what you need.
