Ultra miniature flexible circuits are highly complex devices with some amazing characteristics. Metrigraphics makes circuits with feature sizes ranging from 3 to 10 microns, some of which are so flexible they can wrap around a pencil. Some of our ultra miniature flex circuits have as many as 6 layers (although 6 is not our limit), some can withstand extreme mechanical loads, and some can perform without fault for years in such adverse and critical environments, such as human body implants.
These circuits meet a wide variety of performance requirements; however, a flex circuit that meets one application’s particular requirements, likely will not meet the requirements of another. Each application is different, so the circuit must be different too, and so must be its manufacturing process.
