Custom Thermal Test Enclosure (CTTE) (Optional)
The CTTE is
an
optional enclosure which allows manual probing at temperature of PCBs, component arrays
and small subassemblies.
One CTTE design configuration is to utilize Temptronic's patented "pierce-through, fog-free window," a
three pane transparent surface which self heals the original puncture after
the
probe needle is retracted from
the PCB or subassembly under test.
A
purge air feature keeps the windows frost-free.
A
CTTE can be configured with a "pierce-through, fog-free window" on two sides to allow two operators
simultaneous access, or one operator access to both sides without having to remove, rotate and reinsert the
Device Under Test.
CTTEs are available for both edge-connector and in-circuit bed-of-nails PCB test applications and can be
configured to meet a variety of test requirements.
A
ThermoFixture holds the module or device in a custom socket at temperature in
an
airtight environment
and utilizes dual-loop direct DUT temperature sensing.
However, to sense and to control air temperatures in a Custom Thermal Test Enclosure, an external DUT
sensor is located in the air exhaust port and thermocouples are then connected to the ThermoStream7s DUT
controls.
