Abstract:
A circuit board to be mounted on a printed circuit board and a mother laminated body are provided, the circuit board being capable of suppressing detachment thereof from the printed circuit board even if the printed circuit board is deformed. A laminated body (11) is configured by induing insulation layers (16) composed of a flexible material that are stacked on one another. External electrodes are provided on a bottom surface of the laminated body (11). Ground conductors (18a, 18b) are provided in the laminated body (11) and harder than the insulation layers (16). The laminated body (11) includes a flexible region (E2) and a rigid region (E1) that is adjacent to the flexible region (E2) when viewed in a plan from a z-axis direction, The rigid region (E1) is defined by the ground conductors (18a, 18b) when viewed in a plan from the z-axis direction, The external electrodes are provided within the flexible region (E2) when viewed in a plan from the z-axis direction.

Abstract:
Buffer structures are provided that can be used to reduce a strain in a conformable electronic system that includes compliant components in electrical communication with more rigid device components. The buffer structures are disposed on, or at least partially embedded in, the conformable electronic system such that the buffer structures overlap with at least a portion of a junction region between a compliant component and a more rigid device component. The buffer structure can have a higher value of Young's modulus than an encapsulant of the conformable electronic system.
