Abstract

The invention relates to a resin composition, and particularly relates to a thermal conducting resin composition having a laser direct structuring function, a preparation method of the resin composition and applications of the resin composition. The resin composition comprises 15-60 wt% of resin matrix, 30-70 wt% of a thermal conducting filling material, 1-10 wt% of metal oxide sosoloid, and 0-15 wt% of other additives. The resin composition has excellent high-temperature resistance and good thermal conductivity, and is capable of selectively depositing copper, nickel, gold, and other metal in a laser scanned area. The resin composition can be used for workpieces of surface mounting technology (SMT), and is mainly used for the field of electronic and electrical components.

Description

technical field [0001] The invention relates to a resin composition, in particular to a thermally conductive resin composition with the function of laser direct structuring (Laser Direct Structuring), a preparation method thereof and an application of the resin composition. Background technique [0002] Laser direct structuring (LDS) technology refers to the use of computer to control the laser scanning area, irradiate the laser light on the workpiece containing laser sensitive additives, activate the circuit pattern, and the activated area on the workpiece can be electroless electroless plating Deposit metals such as copper, nickel, gold, etc., so as to realize the manufacture of conductive patterns on three-dimensional plastic parts. [0003] With the rapid development of laser direct structuring (LDS) technology, the production speed of molded interconnect devices (MouldedInterconnectDevice) is faster, the process is more simplified, the cost is more controllable, and the...
