BASF Has Material Expertise and Know-How with Laser Welding

Ultradur® PBT ideal for electronic components

WYANDOTTE, MI, June 22, 2009 -- BASF's expertise in laser welding and material science culminates in the Ultradur B4300 G6 resin, which provides the superior strength and stability required of the laser energy transmission (LET) process, easily supporting high precision laser welding.

BASF's joining technology experts have developed a unique method of testing LET, with findings verified by various electronic component suppliers. By developing a refined understanding of the interaction between the resin, part design and laser welding process, BASF has achieved optimal laser welding performance for electronic components. This LET technology minimizes the potential for damage or contamination of the ever-sensitive electronic components by creating a water-tight seal throughout the service life of the part. These attributes ensure consistent product performance time after time, as well as the reliable laser welding of electronic components.

"With the right design and our Ultradur B4300 G6 PBT grade, component suppliers can save on complexity and cost in both the assembly and the supply chain by eliminating traditional forms of joining, such as adhesives and fasteners," said LeeAnn Marougi, Electrical/Electronic Market Sector Leader for BASF.

BASF's Engineering Plastics product portfolio has a broad range of materials that are beneficial and globally accepted for use in joining technologies. Ultradur® PBT and Ultramid® Polyamide are also used in automotive applications, such as vibration welded air intake manifolds and interior components using adhesives.
