Automatic selective conformal coating
 
   Conformal coatings protect electronic products from solvents, moisture, dust, or other contaminants that may damage them. Coating also prevents dendrite growth, or oxides growing on the Printed Circuit Board (PCB). Dendrite growth can create short circuits and result in product failure.

   Major improvements in the conformal coating process can be realized through the use of automated systems that selectively apply coating. A dispenser mounted to a robot is programmed to move and dispense material in designated locations on the PCB. The system is equipped with conveyors for in-line board processing. The coating material, dispenser type, and robot speed determine the coverage and film build. Selective conformal coating machine provides a consistent application of material, higher throughput, material savings, closed fluid systems, and with the proper dispenser and PCB layout, do not require custom tooling or board masking. As a result automated system can provide sizable cost savings as well as the high level of the flexibility and additional process controls of a selective conformal coating.

   Our PCB assembly line is equipped by Selective Conformal Coating System which provides consistent, uniform dispensing of a variety of conformal coating materials for inline coating applications. The system virtually eliminates the requirement for labor-intensive board masking, providing accurately controlled patterns, film builds, and production flexibility in an automated process.

   We use special coating material which is suitable for automotive applications.
