Description

technical field [0001] The invention relates to the field of laser marking, in particular to a radium engraving powder used in laser marking and a preparation process thereof. Background technique [0002] Mobile and portable consumer electronic products are becoming more and more popular. In order to improve portability, the current consumer products are required to be light in size and weight, and the development trend of thinness. In order to meet the needs of the market, laser direct structuring (LDS: Laser Direct Structuring) technology materials have emerged, which can save space and reduce the weight of mobile devices. Materials can be used with specialized lasers to etch a component's circuit pattern onto a molded plastic part, which is then plated to create a circuit that exactly matches the laser pattern. However, due to the unsatisfactory flame retardancy of the existing materials used for laser radium engraving, for example: the single polycarbonate flame retard...

Problems solved by technology

However, due to the unsatisfactory flame retardancy of the existing materials used for laser radium engraving, for example: the single polycarbonate flame retardant level is BI level, during the radium engraving process, due to the high temperature of the laser, the material is combustible, and the engraving When the material is flammable and deformed, the accuracy is greatly reduced. At the same time, once the material is flammable, it will cause a great safety hazard. Therefore, we propose a laser engraving powder for laser marking
