Plasma Etch BT-1 | Aerospace Case Study
Contaminates: Hydrocarbons, Organic
Substrate: Illuminated Push Button Switches
Equipment Used: Plasma System, Model BT-1
Details of Application: BT-1
This company is a leading supplier of illuminated switches to the Aerospace Industry.
They bond NVG glass with an acrylic and fiber optic plate. They use an RTV (Room Temperature Vulcanizing) epoxy to bond the materials together to produce illuminated push button switches.
The acrylic substrate is processed to activate the surface. This surface activation on the acrylic increases it's ability to bond with the fiber optic plate.
Studies have shown that plasma subsequent to bonding will increase the lifetime reliability of the bond. This company chose Plasma Etch, inc. because we offered the most inform etch, along with the shortest cycle time.
This company uses an oxygen plasma to activate the acrylic surface to increase bond strength.
