Click here to download the sample report What Are Molded Interconnect Devices (MIDs)? A Molded Interconnect Device (MID) is a three-dimensional plastic component that integrates both mechanical structure and electrical circuitry. Unlike conventional printed circuit boards (PCBs) that are flat, MIDs allow circuit paths to be directly created on 3D molded surfaces, offering a powerful platform for product miniaturization. Key highlights of MID technology include: •
Integration: Mechanical and electronic parts combined in one component.
•
Miniaturization: Compact designs enable lighter and smaller devices.
•
Functionality: Circuits can follow complex 3D geometries.
•
Efficiency: Reduced material use and simplified assembly.
•
Reliability: Improved durability compared to traditional PCB assemblies.
The three main manufacturing techniques for MIDs are: 1. Laser Direct Structuring (LDS): Uses laser beams to create conductive paths on molded parts.
2. Two-Shot Molding: Involves molding two different plastic materials where one can be metallized for circuits. 3. Film Insert Molding: Conductive foils or films are inserted into plastic parts during molding.

Technological Foundations of MIDs 1. Laser Direct Structuring (LDS) LDS remains the most widely adopted technique for MID production due to its flexibility. The process involves: •
Molding plastic with laser-activatable additives.
•
Using lasers to “draw” the circuit pattern.
•
Applying electroless plating to deposit conductive traces.
This enables fine circuit geometries and rapid prototyping, making LDS ideal for customized, high-precision components. 2. Two-Shot Molding This method involves injecting two polymers into a single mold. One polymer is metallizable, forming the circuit base, while the other provides structural support. This results in robust and highly reliable circuits integrated into structural components. 3. Film Insert Molding Conductive foils or films are pre-patterned and inserted into the mold. This allows highvolume manufacturing of complex parts, making it ideal for consumer electronics and automotive components.
