TCU Temperature Control Unit
Thermal Control at the Flip of a Lid -
Introducing WELLS-CTI's New Direct Touch Thermal Forcing System
WELLS-CTI's new Thermal Control
Unit (TCU), the DT-0504 is the
industry's most compact tool for
thermal control. It uses DTT, Direct
Touch Technology, to enable the
industry's fastest and most accurate
thermal control technology for
precision control of temperature
during device characterization.
DTT also eliminates the issues
associated with handling of thermal
interface materials.
Unlike forced air systems the DT-0504 allows bench level data collection without stressing other
peripheral components. The unit is a self-contained closed loop system which is easily integrated
into your PCB, SLT, or bench environments. Users can confidently operate the unit remotely, or
unsupervised, as condensation is eliminated and the test temperature is controlled by the software.
Ideal for the telecom market, the DT-0504 will fall within size constraints of any bench top
environment. Using device temperature monitoring the user can accurately control IC's to within
+/-2°C regardless of device wattage or finite space requirements.
The modular design allows quick changes to accommodate different package sizes and types and is
easily adapted to test sockets and PC board footprints to match the smallest footprint size constraints.
The micro size facilitates use of multiple units side-by-side on ATE bench platforms for system level
or product validation testing.
DT-0504 dares to go where no Thermal Stream has gone before . . . your desktop!
