Common problems in PCB screen printing pre-processing include dotted oxidation on the copper surface, darkened copper areas after printing blocking, and areas that are not brushed. Regular maintenance of equipment such as brushing machines and checking the squeezing roller is essential to ensure consistent and effective pre-treatment.
