About MID

MID stands for molded interconnect device. MID are injection-molded plastic parts with integrated electronic circuit wiring to enable mechanical or electrical applications.

MID (Molded Interconnected device)


Conventional boards are flat and square-shaped devices. With MID, wiring is patterned onto the surface of the molded product, providing freedom in board configuration and design.
