    摘要： A circuit board assembly (100), comprising a first circuit board (1) and at least one second circuit board (2). The first circuit board (1) comprises at least one first binding assembly (11), and the first binding assembly (11) comprises a plurality of first conductive blocks (111) sequentially arranged at intervals in a first direction. The at least one second circuit board (2) comprises at least one second binding assembly (21), and the second binding assembly (21) comprises a plurality of second conductive blocks (211) sequentially arranged at intervals; the plurality of second conductive blocks (211) in one second binding assembly (21) are bound and connected to the plurality of first conductive blocks (111) in one first binding assembly (11) in one-to-one correspondence. The expansion rate of the first circuit board (1) is less than the expansion rate of the second circuit board (2); the second conductive blocks (211) in the second binding assembly (21) overlap the first conductive blocks (111) bound and connected thereto, and the change rate of the overlapping state of the second binding assembly (21) in the first direction is less than 0.102%.
