Method of applying an electric conductive layer to selected portions of a mounting frame

摘要

A foam mount of an aircraft window has a groove to receive an electro chromic window. The foam mount is painted by placing a blank in the groove to divide the foam mount into a first section designated to face the exterior of the aircraft and an opposite second section. The foam mount having the blank is placed in a mask or masking device to coat one section of the foam mount while covering the other section. The groove and the first section are coated with an electric conductive paint, and the second section is covered with a decorative paint. The conductive coating on the foam mount and the conductive coating of the electrodes of the electro chromic window provide an RF shielding to prevent electronic signals from personal electronic equipment from passing through the cabin and door windows of the aircraft.

主权项

1. A masking device for exposing a major surface of a window mount for painting while preventing other surfaces of the window mount from being painted, the masking device comprising:
a support plate having a first surface and a perimeter; a plurality of vertical upright pins having a first end and an opposite second end, wherein the first end of the plurality of upright pins are mounted in the first surface of the support plate with the second end of the upright pins extending away from the first surface of the support plate and the plurality of upright pins spaced from the perimeter of the support plate and spaced from one another, and a frame member having a plate member completely surrounding an open area, wherein the plate member is supported on the second end of the plurality of upright pins, wherein with the window mount positioned within the plurality of upright pins and the plate member of the frame member positioned on the second end of the plurality of upright pins, a paint spray passing through the open area of the frame member sprays paint on the major surface of the window mount facing the open area of the frame member and passes through the space between the plurality of upright pins to prevent overspray of the other surfaces of the window mount from being painted.
