Circuit substrate, memory chip and imaging box

Abstract

The invention relates to a circuit substrate, a memory chip and an imaging box. The circuit substrate comprises a hard board and multiple signal ends, wherein the multiple signal ends are arranged in a staggered mode and respectively form, at least, a first row of signal ends and a second row of signal ends which are close to each other. The circuit substrate is characterized by comprising at least one flexible board, wherein one section of the flexible board is fixedly connected with the hard board, the other section of the flexible board is a free section, at least one of the multiple signal ends is arranged at the free section of the flexible board, and grooves are formed in the hard board portion corresponding to the signal ends arranged at the free section of the flexible board. Due to the fact that the grooves are formed in the circuit substrate, elastic electrodes of an imaging device extrude the flexible board portion where the signal ends are located in the contact process of the elastic electrode and the signal ends, the flexible board where the signal ends are located deforms, finally the elastic electrodes are clamped in the grooves and are kept to be electrically connected with the signal ends, electrical connection stability is good, even the influence of dust or oxides on electrical connection can be further reduced, and the contact performance of a circuit is improved.
