The TE4 is a compact thermal (resistive)
evaporator designed for easy retrofit to any existing vacuum coater.
The base plate is configured such that the user
can alter the geometry of the TE4 on the fly, enabling change from 4
hearth sequential deposition to a 2 x 2 co-deposition unit during
routine run loading.
The base plate is also pre-configured for retrofit water cooling which
reduces radiated heat transferred from active to non active boats. This
is vital where metal and organic deposition is undertaken.
Unlike other multi-boat designs, the TE4 does not need to rotate to
connect to a power feed through. Each boat’s power contact is discrete
, giving repeatable results for the same process at the same power
setting.
For customers wishing to retrofit to an Edwards E306 type coater, the
TE4C control unit
replaces the old style variac / meter double bay unit and the 4
position filament switch single bay unit and unbelievably fits into one
single bay. Existing LT transformer(s) can be utilised, but if
co-deposition is required, two
of TE2C controllers replace the TE4C,additional LT transformer and E306
mains power pack ( up to 20A) are required.
Dependant upon the power required, there are a number of feed through
options available. The standard option is for two of one inch bolt feed
throughs which allows for 38A of power and co-deposition or sequential
configuration
Control system:
There are a number of options available for
power supply and control systems.
TE4C: 4 position
filament / boat select switch, digital ammeter display ( actual power
through filament), on / off circuit breaker switch, rotary potentiometer
power control. 3U x ¼ panel rack space for console mounting (eg E306)
TE4C-PS: as
above but with integrated 60A 7.5V power supply, all housed in a 2U x ½
panel steel painted box for
rack mounting.
TE2C: Ideal for those wishing to configure the TE4 to
co-deposition. 2 position filament / boat select switch, digital ammeter
display ( actual power through filament), on / off circuit breaker
switch, rotary potentiometer power control. 3U x ¼ panel rack space for
console mounting (eg E306)
Summary:
Sequential deposition: 1 x TE4, 1 x TE4C, 2 x feed throughs,
1 x transformer (psu), cable set.
Co-deposition: 1 x
TE4, 2 x TE2C, 2 x feed throughs, 2
x transformers (psu), cable set.
