The process for drilling and surface treatment of flexible printed circuit boards involves careful attention to the metallization, cleaning, and film selection to ensure uniform copper layers and precise patterning, with recent advancements in direct electroplating and film methods improving quality and production efficiency.
PCB immersion gold and gold plating are surface treatment techniques that enhance PCB durability and performance by applying thin gold coatings. Immersion gold (ENIG) involves a chemical bath deposition, forming a thicker gold layer through a redox reaction.
