Abstract: The present application relates to a circuit board assembly, a photosensitive assembly, a camera module, and preparation methods for the circuit board assembly and the photosensitive assembly. The photosensitive assembly includes a circuit board and a photosensitive chip. The circuit board includes a circuit board main body, a through hole formed through the circuit board main body, a set of circuit board electrical connecting terminals disposed on the lower surface of the circuit board main body, a conducting medium disposed on the circuit board electrical connecting terminals, and a non-conducting adhesive covering the conducting medium. The photosensitive chip includes chip electrical connecting terminals disposed in a non-photosensitive area.

Abstract: The present application relates to a photosensitive assembly, including a circuit board, a photosensitive chip and a metal wire. A first surface of the circuit board has a protrusion structure and a chip attachment area, and the protrusion structure is distributed in the chip attachment area. The photosensitive chip is attached to the first surface by an adhesive, and the adhesive is at least disposed between the top surface of the protrusion structure and the bottom surface of the photosensitive chip. The metal wire electrically connects the photosensitive chip and the circuit board in a wire bonding manner. The present application further provides a corresponding manufacturing method for a camera module and a photosensitive assembly. The present application can avoid or suppress the deformation of the photosensitive chip at a smaller cost of space size. The photosensitive assembly and the camera module of the present application can improve the structural strength of the circuit board.
