The Kester CB44-7068-0000 is manufactured by a special process that controls the inclusions of oxides and metallic and non-metallic impurities, Kester Ultrapure is the industry standard bar solder for use in high tech electronic applications where lower surface tension and hole filling ability are essential. The purity of Ultrapure meets the requirements of IPC/J-STD-006C and will conform to these requirements when purchased directly or through stocking distributors.

Kester CB44-7068-0000 Features:
  • Yield: Best-in-class yield, outperforms all SnCu-based materials.
  • Wetting speed: Fast wetting, in back-to-back tests 0.65 s compared to 1.00 s, for SnCu-based materials.
  • Low dross generation.
  • Excellent solderability due to fast wetting speed.
  • Very good drainage: Has lower levels of bridging compared to SnCu alloys.
  • Delivers excellent performance across a wide range of flux technologies.

Extruded Bar vs. Cast Bar Process

Wave solder / Selective solder “make up bar” is available in multiple sizes and shapes: Cast, Extruded, Anode, Ingot, etc. Regardless of shape, the purpose of the bar is to replace material in the pot that is removed during the manufacturing process or with the dross. The key is that the bar alloy is always the same no matter the shape of the bar.

With “conventional bar”, the most common shape is either Extruded or Cast. Alpha has historically manufactured Cast Bar. Extruding is a more expensive way to produce bar solder when compared with cast bar.

Is there any difference between Extruded bar vs Cast bar regarding the alloy?

No. Once an alloy is manufactured and ready for forming, the shaping process, whether, extruded or cast, has no impact on the alloy. Extruded and Cast meet the same technical requirements and specifications as they are the exact same alloy and come out of the same master pots.

Is there a difference in the shape between Extruded bar vs Cast bar?

Yes. Specific to the shape and size, there are small differences. Extruded bar has a more consistent size and shape as it is pressed through a die

Extrusion
Cast Process

What is the Cast Bar manufacturing process?

  • First, the solder is made into the desired alloy, (SAC305, Sn63, etc.) in the master pot.

  • Second, as the alloy in the master pot is cleaned of excessive dross and made ready for forming.

  • Third, molten solder is poured directly into a mold or cast and then cooled. The solidified bar is then boxed for shipping.

Differences in using Extruded bar vs Cast bar?
  • Extruded bar is more expensive due to the extra steps required to make the extrusion. Cast bar is formed through a less expensive process.

  • Some equipment has bar solder auto feeders used to top off a wave solder pot which includes a die hole through which bar is fed into the pot. The Extruded Bar, being more consistent in size, may fit better though the die hole of the auto-feeder.

  • When bar solder is hand fed into the pot, cast bar is preferred, as there is no advantage in using the more expensive extruded processed bar.
