Abstract

A substrate with a crack detection function, comprising an installation area for installing hardware, a wiring area, and a detection assembly. The wiring area is set around the installation area. The detection assembly is in the wiring area. The detection assembly includes a plurality of detecting units and a plurality of connecting units. The plurality of detecting units is set around the wiring area. Two ends of each connecting unit are respectively connected to two detecting units, forming a circuit for detecting whether cracks exist in the substrate. Each detecting unit includes at least two detecting endpoints. Each connecting unit includes at least two detecting wires, with each end of one detecting wire connected to one detecting endpoint of two detecting units. The at least two detecting wires between two non-adjacent detecting units are set around outside of the installation area to form a closed loop area.
