Take your conformal coating out of the dark and avoid shadowing effects

Shadowing is where correct conformal coating coverage is not achieved on a section of a board due to a component or part of the board blocking another area of the circuit board.

This can occur when coating is applied by spray method to a circuit board. This can easily occur with 3D components and tall components.
