A recently granted patent (Publication Number: US11885955B2) discloses a unique circuit board design comprising a combination of rigid and flexible circuit board layers. The circuit board includes a chip connection portion and a bending portion, allowing for invertible connection between the two sections. The design enables the bending portion to be flipped to the rear side of the chip connection portion without protruding from the rigid circuit board layer, providing a compact and efficient layout. Additionally, the circuit board may include a reinforcing member on the bending portion to secure the flexible circuit board layer in place.

Furthermore, the patent extends to a circuit board jointed panel and a periscope camera module incorporating the innovative circuit board design. The periscope camera module features a lenses assembly and a photosensitive assembly connected through the circuit board. The circuit board in the periscope camera module includes a rigid circuit board layer, a flexible circuit board layer, a chip connection portion, and a bending portion, facilitating the connection between the photosensitive chip and other components. The invertible connection between the bending portion and the chip connection portion allows for efficient assembly and compact integration within the camera module, showcasing the versatility and practical applications of the patented circuit board design.
