Precision and standardization issues of silk screen printing in the field of printed electronics Regarding the accuracy and standardization issues of silk screen printing in the field of printed electronics, the current core situation can be summarized as follows: there has been a clear breakthrough in accuracy, and laboratories and high-end production lines have reached 50μm or even finer levels; however, the standardization process has seriously lagged behind, becoming the core bottleneck restricting its move from the laboratory to large-scale, high-yield production.
