Title:
CIRCUIT BOARD ASSEMBLY, CIRCUIT BOARD STACK STRUCTURE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/016368
Kind Code:
A1
Abstract:
Provided is a circuit board stack structure comprising: a third circuit board (700), a circuit board assembly, and a second circuit board (500), which are stacked in sequence. The circuit board assembly comprises a first connector (120), a first circuit board (300), and a second connection socket (210), which are stacked in sequence. The first connector (120) is provided with a second electrical connection portion (121) and a second connection portion (122). The second connection socket (210) is provided with a fourth connection portion (211). The side of the first circuit board (300) facing the first connector (120) is provided with a third electrical connection portion (311) and a third connection portion (312). A fourth electrical connection portion (321) is provided on the side of the first circuit board (300) facing the second connection socket (210). A first wire in the first circuit board, a third connection portion (312) in the first circuit board, and the second connection portion (122) are electrically connected in sequence, such that a second path (20) is formed between the first circuit board (300) and the third circuit board (700). The fourth connection portion (211), the fourth electrical connection portion (321), the third electrical connection portion (311), and the second electrical connection portion (121) are electrically connected in sequence, such that a first path (10) is formed between the second circuit board (500) and the third circuit board (700).
