Application Examples

Case study (Joining of dissimilar materials by welding)

Fujikura has developed a dissimilar material joining technology that directly welds the copper foil and aluminum material of FPCs (Flexible Printed Circuits). In general, when welding copper and aluminum, brittle intermetallic compounds are formed at the joint, reducing the joint strength and making it difficult to application. To solve this problem, we have used a fiber laser and a unique welding method that enables joining with reduced intermetallic compound formation. We aim to application this dissimilar material joining technology in high current applications, where the aluminum reinforcing plate, which is commonly used as a reinforcing plate for FPCs, is used as a current path.
