Method for arranging LED lamp beads on side face of PCB in surface-mounting manner

Abstract

The invention provides a method for arranging LED lamp beads on the side face of a PCB in a surface-mounting manner. The method comprises the following steps that 1, a front face connecting terminal pair is arranged on one side of the front face of the PCB, and a back face connecting terminal pair is arranged on the back face of the PCB, and connecting terminal sets are formed by the front face connecting terminal pair and the back face connecting terminal pair of the PCB; 2, the PCB is fixed to a welding jig, the welding jig comprises a left half welding jig body and a right half welding jig body attached to the left half welding jig body, the PCB is arranged between the left half welding jig body and the right half welding jig body, so that first containing space corresponds to the positions of the connecting terminal sets, and solder paste reserved positions are arranged on the first containing space; 3, solder paste is printed on the solder paste reserved positions on the welding jig; 4, the LED lamp beads are arranged in the first containing space on the welding jig in the surface-mounting manner, and pins of the LED lamp beads are in contact with connecting terminals of the connecting terminal sets on the PCB; and 5, reflow soldering is carried out on the welding jig to fix the LED lamp beads. The method has the beneficial effects of being higher in surface-mounting speed and higher in production efficiency.

Description

technical field [0001] The invention relates to a method for mounting LED lamp beads, in particular to a method for mounting LED lamp beads on the side of a PCB board. Background technique [0002] Semiconductor lighting is gradually being widely used due to its obvious energy-saving features and environmental protection functions. Light-emitting diodes are referred to as LEDs, which are a type of semiconductor diodes that can convert electrical energy into light energy. With the development of LED technology and the acceleration of industrialization process, coupled with the guidance and promotion of the government and relevant departments, the application of LED lighting technology in China has been rapidly promoted, and the market scale has continued to expand. LED lighting technology is widely used in advertising signs, street lighting, and display screens. Among them, the most common application is for display screens, also known as LED display screens. When used for di...

Problems solved by technology

[0003] With the development of science and technology, and people pay more and more attention to visual enjoyment, more and more people want to use LED display screens on indoor glass curtain wall screens, or on windows, not only as display screens, but also as It can be used as a decoration; but in the above-mentioned prior art, since the LED lamp beads are mounted on the front of the PCB board, when the PCB board is installed in the display frame to form a display screen and installed on the glass curtain wall screen, the display screen The low light transmittance will make the indoor light dark, which not only affects the lighting, but also affects the appearance; ) to mount LED lamp beads, but due to certain technical difficulties, it can only be mounted by hand, which is not only troublesome, time-consuming, and requires a lot of manpower and material resources, but also slow mounting speed and extremely low production efficiency , the quality of the products produced is also poor
