The Molded Interconnect Device (MID) market is characterized by a sophisticated technological landscape that underpins its unique capabilities for 3D functional integration. At the forefront are advanced molding techniques, primarily two-shot injection molding and Laser Direct Structuring (LDS). Two-shot molding involves sequential injection of two different thermoplastic materials into a single mold, where one material is specially formulated to be activated for metallization. This process allows for precise spatial separation of conductive and non-conductive areas, forming the basis for complex circuit geometries directly on the molded part. It offers high precision and is particularly suitable for high-volume production.
Laser Direct Structuring (LDS) is another pivotal technology, offering immense design flexibility and rapid prototyping capabilities. In the LDS process, a laser beam selectively activates a special additive within a thermoplastic material, creating a micro-roughened surface that can then be chemically plated with conductive metals like copper, nickel, and gold. This method allows for very fine line structures and complex 3D patterns, making it ideal for antenna designs, sensors, and intricate electronic modules. The precision of laser technology enables a high degree of miniaturization and intricate circuit integration that would be challenging with conventional PCB manufacturing.
Beyond molding and laser processes, the MID market leverages significant advancements in materials science and plating chemistry.
