The PCB pre-processing stage is critical for manufacturing quality, involving complex equipment and processes that can be impacted by various factors such as human, machine, material, and environmental issues, which can lead to defects like surface roughness, oxidation, and circuit deformation, and requires careful monitoring and maintenance to ensure optimal results.
Why can PCB pre-processing lead to production issues? Read More »
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.
