The technology of laser direct structuring (LDS) on ferrite substrates was evaluated for the fabrication of fine-line circuits. The LDS technology involves laser activation followed by electroless copper plating. A sieving pattern was scanned by the near IR laser on the ferrite substrates, and electroless copper plating was carried out. The results showed that the LDS technology applied to Ni-Zn-Cu-ferrite films. Appropriate laser activation conditions were chosen to engrave a contrast pattern on ferrite sheet samples. A chosen condition was used to fabricate a line width evaluation pattern, and the results indicated that the feasible fine width could be as fine as 50 μm.
