FPCB SUS Surface Treatment Method of Stainless Steel Plate for Using FPCB Reinforcement

摘要

The present invention relates to a SUS (Steel Use Stainless) plate surface treatment method for FPCB (Flexible Printed Circuit Board). A protective vinyl for plating is attached to one side of the SUS plate for FPCB included in the mobile phone camera module to prevent plating, and the plating layer formed of nickel and tin is stably and uniformly plated on the other side. to improve the flatness, no scratches, and only one side is plated so that the surface roughness of the other side that is not plated is maintained below a certain value, suggesting a surface treatment method for manufacturing SUS plate for FPCB with excellent surface roughness do.
