Embodiment 1

[0016] A radiation-resistant reinforcement method for components. First, prepare the PCB design. The PCB design preparation includes layout design, pad design, package design, and the design of the binding process holes around the components. The PCB is the most important step. If the PCB If the design cannot meet the requirements, it will affect the stability of the reinforcement. PCB design preparation, enter the molding of the second step radiation-resistant material, the radiation-resistant material of the present invention selects lead, the method is the molding method of radiation-resistant material is: ①The forming of lead sheet: the thickness is 0.5mm~2.0mm The lead sheet is cut and formed according to the shape and size of the components to be reinforced, and the edge of the lead sheet is chamfered; ② Marking: Use a laser marking machine or a shell machine to mark on the formed lead sheet; The marking includes the direction, model and batch of components. ③Cleaning an...

Description

technical field [0001] The invention relates to a method for strengthening against radiation, in particular to a method for strengthening components against radiation. Background technique [0002] As spacecraft such as satellites, spacecraft, and space stations operate in space, they are separated from the protection of the atmosphere and are directly exposed to the space environment. Electronic equipment will be impacted by radiation and high-energy particles from outer space and various radiation effects will occur, causing work According to the statistics of aerospace accidents at home and abroad, about 40% of the faults originate from space radiation. Therefore, when using aerospace devices, special anti-radiation treatment must be carried out to ensure the reliability of their work. [0003] There are also many methods of anti-radiation treatment for aerospace devices, some of which are based on chip design and special material applications, such as devices using sapp...
