The advantages of FPC flexible boards, such as being shorter, smaller, lighter, and thinner, are evident with the increasing demand driven by electronic product development. However, common surface defects, like bubbles, often arise due to manufacturing processes. The solution involves ensuring proper screen printing and current control during plating.
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.
