Abstract

The invention provides a modified resin composition for depositing a metal film, and a preparing method and an application thereof. The modified resin composition comprises a resin matrix and a metal oxide solid solution, wherein a metal element in a solvent of the metal oxide solid solution is selected from elements of the third period, the fourth period, the fifth period and the sixth period of the periodic table, a metal element in a solute is selected from elements of the third period, the fourth period, the fifth period and the sixth period of the periodic table, and the weight content ratio of the solute to the solvent in the metal oxide solid solution is 1:9 to 1:1. Under the action of laser, the modified resin composition allows metal particles of the metal oxide solid solution to be released; and in a subsequent non-electrochemical plating, the metal particles play a role in activating centers, metal ions in a chemical plating solution are selectively deposited, and the metal film is formed and can be used for manufacture procedures of a surface mounted technology (SMT).

Description

technical field [0001] The invention relates to a resin composition, in particular to a modified resin composition for selectively depositing metal thin films, its preparation method and its application. Background technique [0002] Laser direct structuring (Laser Direct Structuring, LDS) refers to the use of computer to control the laser beam, the laser beam is irradiated on the workpiece, the area irradiated by the laser beam has activation ability, and the area with activation ability on the workpiece can be chemically Metals such as copper, nickel, and gold are deposited in the plating solution, and metals such as copper, nickel, and gold cannot be deposited in areas not irradiated by laser beams, so that the resin composition has selectivity when depositing metals. [0003] With the rapid development of LDS technology, the production speed of Molded Interconnect Device (Moulded Interconnect Device) is faster, the process is more simplified, the cost is more controllabl...
