Abstract

The invention provides a device and a method for removing magnetism of pins of circuit board components for spaceflight. A winding coil and an insulating track are mounted on an insulating table; the insulating track penetrates through the winding coil in the axial direction, and an insulation tray is installed on the insulating track and used for containing components needing to be demagnetized. And the components pass through the winding coil for multiple times in the same direction, and the components pass through the winding coil for the same times in the opposite direction until the residual magnetism intensity reaches a required value. The device is simple in structure and principle, good in operability, low in production cost, easy to popularize and capable of removing the magnetism of the circuit board component pins, so that the welding quality is remarkably improved, and the cold solder joint risk is reduced.

Description

technical field [0001] The invention belongs to the field of welding of aerospace-level control circuit components, and in particular relates to a magnetic removal technology for pins of board components. Background technique [0002] Due to the particularity of its service environment, aerospace-grade control circuits face the comprehensive effects of complex conditions such as high-level vibration, electromagnetic radiation, extreme temperature and humidity, and high pressure difference, and have high requirements for each link. The welding of the control circuit is affected by many factors such as the quality of components, processing technology, operation level, equipment precision, production links, etc., and is one of the weak links in the production of control circuits. In the harsh service environment, once the phenomenon of virtual soldering and solder joint breakage occurs, it will seriously affect the working status of the control circuit, causing the entire compo...
