|Stokes vacuum coaters are
used to deliver a vapor stream primarily metallic vapors) to a group
of substrate work pieces. On contact the vaporized material
condenses to a solid, forming a thin vacuum coating on the
substrate. The system is composed of four major subsystems:
- The Pumping
System: Develops the proper vacuum level
- The Chamber
System: Houses the substrate holders and is where the "work"
- The Work
Holding System: Is the carriage assembly; it holds the
substrates arranged on a number of work reels
- The Firing
System: Consists of the electrical package for temperature
development, the source holders and the coating sources
multi-step processes for applications such as automotive headlamps
and ceiling louvers. Typical steps include: glow discharge cleaning,
aluminum deposition, plasma polymerization, and silicon monoxide
In addition to
batch coaters, Stokes also offers continuous in-line systems and
small, quick-cycling dedicated units.
extra-heavy aluminum non-reflective coating (varuious thicknesses)
for plastic cellular phone cases, computer components, and other
products emitting high frequencies. The Stokes design is based on a
continuous wire-feed system.
Operation and Maintenance
- System Pump Down - The large diffusion pump system
provides operating pressures at well below 0.1 micron of mercury.
Based upon a clean, dry, empty chamber, the Stokes system will
pump down to 0.1 micron in approximately 5-1/2 to 6 minutes. High
speed pumping in this range permits firing without pressure rise
due to outgassing.
- Cycle Time - The Stokes Coater provides dependable,
consistent cycles, ranging from 8 to 30 minutes under actual
- Auto Pump-Down Auto Fire - A combination of
vacuum-actuated, automatic, and manual firing control permits
duplication of firing techniques, cycle after cycle, in the
automatic mode, while still providing manual override for
operator-controlled firing. The chamber Is automatically pumped
down to the firing pressure by simply actuating one switch. The
operator can then either fire manually or automatically with a
timed firing sequence, depending upon his own techniques.
- Control Panel Maintenance - The newly designed,
fully digital SVC control panel has no exposed electrical
contacts. A full opening access door is provided for ease of
