MODIFIED RESIN COMPOSITION USED FOR DEPOSITING A METAL FILM, PREPARATION METHOD AND USE THEREOF

摘要

A modified resin composition used for depositing a metal film, preparation method and use thereof are provided. Said modified resin composition comprises 35-95wt% of resin matrix, 0-60wt% of additive and 5-12wt% of laser-sensitive additive. The formula of said laser-sensitive additive is XY2O4, which is an equiaxed crystal system, as shown in the drawings of abstract, axis length a=b=c, axis angle alpha=beta=gamma=90°, X and Y being both metal elements from Periodic Table Group ⅢA,ⅠB, ⅡB, ⅥB, ⅦB or Ⅷ. Laser-sensitive additive comprises 0.01-10wt% of metal oxide, based on total amount of laser-sensitive additive. Laser-sensitive additive releases metal particles under the action of laser on said modified resin composition. In subsequent electroless plating, metal particles act as activation center which make metal ions of chemical bath to deposite selectively, and thus a metal film is formed which can be used as parts of surface mount technology (SMT).
