Backboard and electronic device

The invention discloses a backboard and an electronic device. The backboard is used for supporting a circuit board. And a middle sunken part with a bottom is formed on the top surface, facing the circuit board, of the back plate. A protruding main supporting column is formed on the bottom face of the middle concave part of the back plate and used for supporting the circuit board. According to the invention, the main supporting columns formed on the backboard can increase the contact deformation amount of the central area of the socket connector installed on the circuit board and improve the stress uniformity of the socket connector, and the stability and reliability of electric contact between the central area of the socket connector and the electronic chip are improved. 本发明公开一种背板和电子装置。所述背板用于支撑一个电路板。在所述背板的与所述电路板面对的顶面上形成有一个有底的中间凹陷部。在所述背板的所述中间凹陷部的底面上形成有一个凸起的主支撑柱，用于支撑所述电路板。在本发明中，形成在背板上的主支撑柱可增大安装在电路板上的插座连接器的中心区域的接触变形量和改善插座连接器的受力均匀性，提高了插座连接器的中心区域与电子芯片之间的电接触的稳定性和可靠性。
