The application discloses a pps wire needle jig plate burr removing process and relates to the field of PCB test jig manufacturing. The process removes burrs on a pps plate by using plasma, utilizes the physical bombardment and chemical reaction between high-activity particles in plasma and the material surface, effectively and accurately removes burrs based on the "tip effect" and "specific surface area difference" of the burrs, and is provided with a reinforced ion adsorption body in a dense array on a cathode substrate. High-density ion adsorption bodies are arranged at opening positions, positive ions in plasma are gathered and hit the plate area by utilizing the self-bias effect of the cathode, a visual detection scheme and a microneedle plasma generator are added for burrs that are difficult to remove, point-to-point burr removal is realized, the burr removing process is further refined, and the process is essentially a new material detection and standardized processing means.
