Method of applying an electrically conductive layer on selected portions of a mounting frame

摘要

A method of applying an electrically conductive layer (60) to selected portions of a frame of foam (26), the method comprising: providing a frame of foam (26) mount having foam (26) a shape of a frame enclosed surrounding an open area frame having in cross section a peripheral surface (64); opposite to the peripheral surface (64) inner surface (41, 42) defining the inner surface (41, 42) the open area; a first side (50) extending from the peripheral surface (64) to the first portion of the inner surface (42) and an opposite second side (44) extending from the peripheral surface (64) to the second portion the inner surface (41), wherein the inner surface (41, 42) of the frame of foam (26) includes an open end of a slot (30) and the open end of the slot (30) is oriented towards the open frame of foam (26) area, and the first portion (42) is on one side of the open end of the slot (30) and second portion (41) is on the other side of open end of the slit ( 30); applying a first electric conductive coating (60) on the inner surface (61) of the slot (30); inserting the peripheral edge of a substrate (70) in the recess (30) to completely cover the open area of ​​the frame of foam (26) to separate the frame foam (26) into a first section and a second section, wherein the first section comprises the first side (50) and the first portion (42) and the second section comprises the second side (44) and second portion (41); applying a second electric conductive coating (60) on the first portion, wherein the coating (60) on the first portion (42) and the coating (60) on the inner surface (61) of the slot (30) contact each other, and applying a coating electrically non-conductive (62) on the second section.
