Description

technical field [0001] The invention relates to the field of materials, in particular to a polyphthalamide composition and a preparation method thereof. Background technique [0002] Three-dimensional molded interconnect device (3D-MID), also known as three-dimensional circuit or three-dimensional circuit, refers to the production of wires and graphics with electrical functions on the injection-molded plastic shell, so as to realize the electrical interconnection of ordinary circuit boards. The connection function, the support component function and the support and protection functions of the plastic shell are integrated to form a three-dimensional circuit carrier, that is, a three-dimensional molded interconnect device. Three-dimensional molded interconnection devices have the design advantages of being able to choose shapes according to design needs, new functions, and suitable for smaller and lighter development trends. It also has the advantages of reducing installation ...
