The invention discloses a PCB separate aluminum cover hole plugging method, which comprises the following steps of: (1) judging whether separate aluminum cover data needs to be manufactured or not according to different aperture sizes and different hole patterns, and manufacturing a corresponding aluminum cover hole plugging plate if the separate aluminum cover data needs to be manufactured; (2) adding a first aluminum cover hole plugging plate on the conventional hole plugging net for scraping, printing and hole plugging, and rolling to be flat; then, taking out the first aluminum cover hole plugging plate, and adding a second aluminum cover hole plugging plate for scraping, printing and hole plugging and rolling to be flat; if a plurality of aluminum cover hole plugging plates exist, performing the operation in sequence; and (3) after hole plugging is completed, performing normal exposure, development and curing operations, and then manufacturing a finished PCB through molding, surface treatment and functional testing. According to the PCB aluminum cap separating and hole plugging method, the process is simple, the standardization degree is high, the operation time can be shortened by 12-24 hours compared with the operation time of a method for soaking, washing and reworking through one aluminum cap hole plugging plate, and the quality stability is high.
