Thermal Platforms
High Performance
Conduction thermal testing with full component access
Sigma Systems Thermal Platforms/Hot Plates offer a fully open work surface with ultra-fast heating and cooling. The ideal solution for direct testing of chips, RF modules, and PCBs requiring multiple probe points or optical access.
-100°C to +200°C
LCO2 / LN2
Compact Benchtop
Why choose a thermal platform?
Ideal when access to components (electrical probing, optical inspection) is more important than testing in a conventional chamber.
-100°C to +200°C
Extreme thermal range for testing components and modules via direct contact.
Ultra-fast ramps
Rapid thermal transitions for maximum throughput on test lines.
Open surface
Full DUT access — ideal for probe integration, wiring, and test equipment.
High Uniformity
Precise, uniform control across the entire platform surface for reproducible results.
Connectivity & ATE
Ethernet, RS232, IEEE-488 interface for integration into automated systems (TS Controller).
Benchtop Format
Compact, ergonomic design optimized for laboratories and optical inspection.
Optimized for Lab or Production Test Throughput
Sigma Systems has a library of base models offering the flexibility to select the configuration you need. Thermal platforms provide LCO2 and LN2 cooling or mechanical cooling (single-stage or cascade compressor) to meet rigorous temperature requirements, covering any range between -100°C and +200°C.

Application Examples for Thermal Platforms
Sigma Systems provides thermal platforms for a myriad of electronics test and characterization applications — RF components, power devices (IGBTs & MOSFETs), and heat sinks, to name a few. Precise temperature control, thermal range, and rapid transitions meet commercial, military (MIL-STD), or beyond specifications.
Power Components
Testing MOSFETs, IGBTs and RF modules requiring high thermal dissipation.
Microscopy & Analysis
Temperature-controlled samples under microscope or optical inspection systems.
Optoelectronics
Characterization of lasers, photodiodes, and sensors requiring a stable thermal base.
Production Testing
Fast burn-in and component sorting on manufacturing lines.
Controlling Thermal Platforms with Precision
TS Series Controller
The TS series controller from Sigma Systems offers touchscreen operation and real-time graph creation, plus two types of control: system control and DUT (Device Under Test) control. The DUT control mode offers the fastest method to bring your component to the correct temperature.
Whether for design verification, failure analysis (FA), quality testing, or production verification per commercial or MIL-STD specs, the TS controller ensures throughput and precision.
- Real-time data and graphs
- Built-in diagnostics
- Independent built-in safety (Fail safe)
- CE approved
Upgrade: TSR Series Controller
The TSR controller was specifically designed to replace legacy C, CC3, CC3.5 and C4 controllers used in older Sigma Systems platforms and chambers. It has exactly the same physical dimensions allowing easy mounting. Its compatible syntax allows existing programs to run without rewriting, while adding the benefits of touchscreen, Ethernet, USB and real-time graphs.
- Fully compatible with legacy controllers
- Intuitive touchscreen programming
- Adjustable DUT control mode
- Real-time performance (digital and graphical)
- Added communications — Ethernet & USB
Accessories for Platforms & Plates
Sigma Systems offers a wide range of accessories to optimize your conduction thermal testing, protect your components, and ensure operator safety when using cryogenic cooling methods.
Platform Controllers
The TS series controller offers touchscreen operation, real-time graph creation, and independent equipment and DUT control.
LCO2 / LN2 Cryogenic Hoses
Vacuum-insulated transfer hoses essential for safe and reliable delivery of cryogenic fluid from source to the environmental chamber.
Thermal Covers
These covers protect operators, create a thermally uniform environment, and prevent condensation or frost on component surfaces.
LCO2 / LN2 Dewar Accessories
Vacuum lines, special connectors, and valves for high-pressure cylinders or bulk delivery systems, with safety pressure relief valves.
Hold Down Clamp Sets
Specifically designed clamp sets to firmly and safely hold your components bonded or placed on the hot/cold plate.
Gas Purge Systems
Often used to drastically reduce humidity and oxygen, limiting frost at low temperatures and preventing accelerated oxidation at high temperatures.
Mufflers and Exhaust Options
Exhaust devices to direct expelled fluids (LCO2/LN2) away from the user. Two muffler options to considerably reduce ambient noise pollution.
Tapped Holes & Adapter Plates
Inch or metric (M4/M6) tapped holes drilled into the platform to simplify element attachment. Interface plates for card mounting.
Temperature Probes (Type T, RTD)
Measure close to your component with isolated probes that provide precise monitoring of the device-under-test setpoint.
Cryogenic Valves & Filters
Options to keep equipment in perfect condition or adapt systems (e.g. LN2 to LCO2 valve conversion).
Probe Terminal Block
A specially designed terminal block providing an extremely easy connection and anchoring point for additional or DUT-type probes.
