Problems solved by technology

However, this welding method has certain defects in the actual use process. For example, due to the large hole diameter of the pin hole, the position of the pin is prone to deviation or loosening during welding. When soldering the pin, due to the deviation Or loosening will cause the fixed amount of solder during welding to fail to weld the pins firmly, and there will be a phenomenon of virtual welding. If the solder is repaired again, the solder is too large to easily touch the circuit wire next to it, causing a short circuit

Abstract

The invention discloses a position-accurate auxiliary device for diode pin welding, which comprises: a circuit board and a limit ring; pin jacks are provided on the circuit board, and diode pins are placed in the pin jacks; The inner wall of one end of the pin insertion hole filled with solder is provided with a first tapered edge inclined away from the center of the hole from the inside to the outside; the limiting part is sleeved on the pin and fixed on the The pin insertion hole is away from the end of the first tapered edge. The setting of the limiting ring and the first tapered edge on the circuit board in the present invention makes the position of the pins stable, the welding effect is good, and the solder is not easy to leak, and will not affect other circuits.

Description

technical field [0001] The invention relates to the technical field of diode installation, in particular to an auxiliary device for accurate position welding of diode pins. Background technique [0002] Diode is one of the most commonly used electronic components. Its biggest characteristic is one-way conduction. At present, light-emitting diodes are widely used in indicator lights of various electronic products, light sources for optical fiber communications, indicators of various instruments, and lighting. [0003] When using the diode, the pins need to be welded on the printed circuit board. At present, when welding the diode, in order to facilitate the insertion of the pins, the aperture of the pin jack is generally set to 4-7 times the diameter of the pins. However, this welding method has certain defects in the actual use process. For example, due to the large hole diameter of the pin hole, the position of the pin is prone to deviation or loosening during welding. When...
