Online selective coating machine

online selective coating machine is an advanced piece of equipment used in electronics manufacturing to apply protective coatings to specific areas of a printed circuit board (PCB) while leaving other areas uncoated. This precision coating process is essential for protecting sensitive components from moisture, dust, and other environmental factors without compromising the functionality of other parts. The machine operates as part of an automated production line, ensuring high efficiency and consistent application. It uses programmable paths and selective nozzles to accurately apply the coating, making it ideal for high-volume production with stringent quality requirements.
