Cobar Intros Selective Soldering Package
Selective solder kit.
Breda, Netherlands — The Balver Zinn Group's Cobar Solder Products Inc. is introducing a complete selective soldering package — a collection of soldering materials that are especially designed to provide the most reliable solder joints when using a selective soldering system. Selective soldering has overtaken wave soldering applications and has some critical areas that can only be overcome using the right materials, process control and knowledge.

The company offers four different fluxes that have the precise properties for high-temperature applications and are chemically inert even when they are not activated. According to the company, these fluxes will overcome any concerns about reliability, dendrite formation or corrosion issues. These fluxes have excellent spreading properties, and the low-VOC flux types are environmentally friendly since they minimize alcohol emission.

The company provides chemicals and metals, and all of its fluxes are optimized to work with the metals that it manufactures.

The solder alloy package is diverse, containing different alloys offered in wire on a reel, and different wire diameters are available; plus special small 500-gram solder bars, or hemispherical pallets. In addition, the package contains special materials such as a nozzle cleaning chemistry in case wettable nozzles are used in the process.

The SN100C alloy is the most dedicated alloy for selective solder applications because of its low copper leaching and low metal erosion. The package also includes solder sample analysis free of charge, performed at the Balver Zinn/Cobar lab, which will analyze the solder bath sample and provide recommendations.
