Plating process on Intenna parts, LDS
Products Application Guidance

Among the built-in Antenna parts, circuits formed by laser are sorted as LDS parts group. LDS processing method ,in addition to intenna products, has the merits on making construction surface of automobile airbag, hearing aid, connectors, and various foods of sensor small, lightweight, thin, and short of those whole products through forming the pattern by laser. As materials contain metal catalyst and the metal being activated by laser, plating process design needs full understanding about the materials.
