Abstract

The invention relates to the technical field of LED (light-emitting diode) display, and provides a welding copper column for a PCB (printed circuit board), which comprises a column body and a base plate part, the base plate part is arranged at the fitting end of the column body, the end surface of the fitting end of the column body is concave, at least one opening is formed in the base plate part, and the opening is communicated with the outside and the concave. More tin can be connected with the fitting end by arranging the concave part on the base plate part of the column body, liquid tin can conveniently flow in and flow out by arranging the opening, the liquid tin can be ensured to fully circulate at the bottom of the copper column, and the tin is fully contacted with the fitting end, so that the stability of the copper column is enhanced.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to a welding copper column for PCB. Background technique [0002] With the rapid development of the LED display industry, the pixel pitch of the LED display is getting smaller and smaller. The traditional structure of fixing the light board with screws from the lamp surface to the bottom shell cannot be realized because the gap between the LED lamp beads is too small. At present, most of the industry adopts the method of fixing metal copper pillars on the back of the light board and locking the copper pillars on the bottom shell. [0003] The patent with the patent number CN202020308375.5 provides a copper column for LED display screens to fix PCB boards, including a connecting part and a chassis part, the chassis part is located at one end of the connecting part, and the diameter of the chassis part is larger than The diameter of the connecting portion, the edge of the chassis...
