The reasons for the misalignment between the shell hole site and the copper pillar include: (1) because certain tolerance exists in the hole site of the shell and the circuit board, certain angle inclination exists in the process of welding the copper column on the circuit board, and the accumulation of all the errors can cause obvious incorrect alignment; (2) when the shell expands with heat and contracts with cold, the hole position of the shell can generate certain displacement along with the change of the size of the shell, and the hole position of the shell and a copper column welded on the circuit board can generate certain displacement due to the large difference of the thermal expansion coefficients of the circuit board and the shell.

For the second reason, in order to reduce the influence of displacement of the copper pillar welded on the hole site of the housing and the circuit board when the housing expands with heat and contracts with cold, at present, the following method is generally adopted: (1) the welding strength of the copper column and the circuit board is increased, the specific measures include increasing the welding area, adopting high-cost tin paste, repairing welding and the like, the technical means can improve the yield to a certain extent, but the problem of stress cannot be fundamentally solved, the cost is increased, and the production efficiency is reduced. (2) The shell with the low expansion coefficient is generally made of plastic materials or metal materials doped with carbon fibers with a high proportion, so that the displacement problem caused by expansion with heat and contraction with cold can be well avoided, but the cost of the shell made of the plastic materials of the carbon fibers is far higher than that of the conventional plastic shell. Therefore, it is necessary to develop a connection structure that can prevent the circuit board from being detached from the housing and can prevent the circuit board from being easily damaged by thermal expansion and contraction.
