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.
