Gold plated Tungsten and Molybdenum wire for demanding applications

Important results from the project

Main goal: Develop a new electrolytical plating process to produce an Au coated W and Mo ultra-thin wire ( 20 µm) with enhanced quality; also to develop a new digital vision system for on-line quality control. A Ni free patentable adhesion promoter and a process optimization has been performed, resulting in improved market positions in medicine and space applications. A highly customized vision system has been innovated for the ultra-thin wires. The enhanced fundamental knowledge established will be a base for further development of Luma.

Expected long term effects

The Ni free and optimized process innovations, including the vision system are expected to result in higher quality and an improved sustainability of Luma´s business and the customers of Luma. A prolonged lifetime of the processes and less energy consumption and improvements of the work environment is to be expected. Future removal of H2(g) in the process may also be a consequence. The market position will be significantly improved. The project will also result in data for several scientific publications.

Approach and implementation

Despite the COVID-19, good communication and the management have been fulfilled. All parties have been important and all have performed their commitments. Fixed monthly digital meetings have been held. Each sub-group (vision, electrochemistry) has been responsible for internal meetings and reported to everyone during the monthly meetings. Quarterly reports have been written. 2 physical workshops have been carried out. Additional physical meetings have taken place within the two groups (2 times).
