Battery packs for electric vehicles have various cell types and formats that have to be interconnected. They differ not only in the geometry, but also in the current ratings for the interconnections. In addition, there are connections for the BMS (Battery Management System) which require further separate bonding solutions.

More than 40 years of experience in wire bonding ensures our mastery of the technology, even for the most challenging of materials. For the entire evolution from product development to series production, F & K DELVOTEC offers tailor-made support at every stage: from process development, sample bonding, bonding for prototypes, small series manufacture through to process support during series production. Our automation is made to measure; Industry 4.0 naturally.
