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 positional precision auxiliary device for soldering diode pins. The device comprises a circuit board and a stopping ring, wherein pin jacks are formed on the circuit board; pins of the diode are placed in the pin jacks; the inner wall of the solder-coated end of each pin jack is provided with a first tapered edge inclined from the inside to the outside away from the center of the jack; a stopping portion sleeves the pin and is fastened to the end of the pin jack away from the first tapered side. In the invention, the stopping ring and the first tapered side of the circuit board are arranged to make the pins are stable in positions and good in soldering effect, and the solder is less likely to leak, and does not affect other lines.

Description

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