Model PET-5 Protype Engineering Thermal Work StationsDut Board mounted Thermal prototyping forced air hot and cold workstation

The next generation of Prototype Engineering Work Stations (PET), A bench top test and temperature forcing system designed for the hand testing of individual electronic devices, ICs, under precise controlled conditions of heat and cold without the expensive and diffuculty of liquid fluid, or an inaccutrate thermoelectric module peltier. Exatron's state-of-the-art refrigeration temperature forcing system. Simply better.

The PET-5 test and temperature forcing system mounts directly to nearly any test head or DUT board and features Exatron’s direct contact Wide Range Thermal Head (WRTH), allowing a full working temperature range of -55°C to +155°C (-75°C to +175°C hardware capability).

There are two base models:
(See below for shared features.)

PET-5M = Manual Work Station:

Manual buttons toggle WRTH left/right and up/down motion.
Manually adjusted air pressure control.
No computer or software required.

PET-5 C – Computerized Work Station:
WRTH raises/lowers automatically over test socket with the push of a button.
Added cylinder moves WRTH side to side.
Dual start switches, requires two hands to start test.
Requires PC or laptop with 2 unused USB2 ports. (Sold separately)
Robust automation software:
Set and monitor temperature.
Control soak timer.
Start test switch and pass/fail indicator.
Control test socket pressure. (Requires regulator, sold separately.)
Test and temperature data log standard.
Intuitive diagnostic and service screens.

Shared PET-5 Features:
Wide Range Thermal Head (WRTH).Test and Temperature Forcing Systems
-55°C to +155°C minimum working temperature range. (-75°C to +175°C hardware capability)
+/-0.5 degree temperature control.
No fluids required. (See WRTH data sheet for details.)
Built-in purge cover for thermal head and test socket.
Allows placement/removal of devices without thermal head having to heat/cool to room temperature.
Greatly reduces dead time between tests.
Purge requires dry, clean air. (Air dryer sold separately.)
Includes on set of thermal head tooling, designed to match a specific device and test socket.
Attached chiller sits on floor behind or on the side.
6 ft (2 m) hose runs from chiller to PET-5.
Benchtop model available. (See PET-4 Image Below.)
Meets or exceeds all known ESD specifications.
Built-in ESD wrist strap attach points.
Built-in quick-disconnect air fitting for optional vacuum wand.
