The PCB wet process brown oxide machine plays a vital role in the PCB wet process, and its core functions are mainly reflected in four aspects:Enhance Interlayer Bonding Strength: The brown oxide machine generates a uniform and micro-rough brown oxide film on the surface of the inner copper foil.
PCB Wet Process: Core Processes and EquipmentWet processing is a critical stage in the manufacturing of printed circuit boards (PCBs). Centered on chemical treatment, it covers substrate pretreatment, through-hole metallization, circuit patterning, solder masking, and surface finishing.
The machine utilization flow for the PCB wet process typically involves multiple stages, each requiring specific machinery and equipment. Below is an overview of a typical PCB wet process machine utilization flow
