Conformal coating selective spray coater

ICT PCBA Conformal Coating Machine

A conformal coating machine is an industrial device used in electronics manufacturing to automatically apply a protective conformal coating to printed circuit boards (PCBs). This coating shields sensitive electronics from external influences such as moisture, dust, chemicals, corrosion, and temperature fluctuations.

The machine applies a thin, uniform protective layer to selected areas of the PCB. This process is fully automated and reproducible, which is essential for quality and reliability in serial production.

Transport System
Transports PCBs through the machine (inline or stand-alone).
