What is a Temperature Forcing System?

By KNS Rao

Former Project Director, IRNSS, ISRO

Thermal Forcing System

Temperature forcing systems, often known as thermostream or Air stream systems, offer rapid, precise thermal cycling of electronics, chips and, IC’s as well as semiconductors. These specialized tools are instrumental in the testing and development lifecycle of electronic components and devices.

More specifically, a temperature forcing system is a meticulously controlled environment system capable of precisely regulating temperature (between -100 to 300°C), humidity, and other environmental factors. This allows engineers to simulate a vast array of real-world scenarios, including extreme heat, frigid temperatures, or rapid thermal cycling, that the hardware might encounter during real-world operation.

By subjecting devices to these simulated environments, engineers can proactively identify and address potential weaknesses before the products are released to the market.

Types of Temperature Forcing Systems

There are two main categories of temperature forcing systems:

Temptronic Temperature Forcing Systems: These systems use cascaded mechanical refrigeration systems and heaters to precisely control the temperature and force it on your Device Under Test (DUT) using compressed air. They are known for their high precision and rapid temperature cycling capabilities, making them ideal for applications requiring strict temperature control and fast temperature changes.

inTEST Thermal Temperature Forcing Systems: These are Benchtop temperature forcing systems – ie, they are smaller and more compact systems designed for use on a workbench or tabletop. They are typically used for testing smaller components and devices and offer a good balance of functionality and affordability.

Applications of a temperature forcing system

Temperature forcing systems have a wide range of applications across various industries:

Temperature Forcing System

Electronics Manufacturing: Precision Temperature Forcing systems are paramount for guaranteeing the functionality of delicate components across a spectrum of temperatures. This involves testing parameters like coefficient of thermal expansion (CTE), solder joint integrity, and electrical performance at various temperature points. Thermonics temperature forcing systems excel in applications demanding high-precision temperature control and rapid thermal cycling. This becomes critical when evaluating the reliability of integrated circuits (ICs) and other sensitive electronics under fluctuating thermal loads.

Automotive Industry: Temperature forcing systems are employed to assess the performance of automotive components used in engines, batteries, and electrical systems under extreme temperature conditions. This involves testing factors like cold cranking amperage (CCA) of batteries, engine performance in scorching heat, and material stability under thermal stress.

Aerospace Industry: These systems are essential for testing the functionality and durability of aircraft components and materials in various simulated flight environments. This involves replicating the low temperatures experienced at high altitudes, ensuring the components can withstand the harsh conditions encountered during flight.

Medical Device Industry: Temperature forcing systems are used to guarantee the proper functioning and safety of medical devices under varying temperature conditions. This is especially critical for devices used in critical care settings, where maintaining consistent performance is vital. Testing may involve ensuring sterility in high-temperature sterilization processes or evaluating device functionality at varying patient body temperatures.

Consumer Goods Industry: Manufacturers of various consumer goods, such as household appliances and personal electronics, use it to test the durability and performance of their products under different temperature extremes. Understanding factors like thermal runaway and component selection for appropriate temperature ranges becomes important during the design phase.

How to select the best temperature forcing system

Choosing the right temperature forcing system depends on various factors, including:

Temperature range: The system should be able to achieve the desired temperature range required for your specific testing needs. Some systems offer a wide range, while others are designed for more specific temperature control.

Chamber size: The chamber size should be large enough to accommodate the devices or components you need to test. Consider the size and quantity of your test objects when choosing a chamber.

Features: Consider the specific features you need, such as programmable temperature control, humidity control, data logging capabilities, and safety features. Precision temperature forcing systems often come with additional features like rapid heating and cooling rates, which can be essential for specific testing protocols.

Budget: Temperature forcing systems can range in price depending on their capabilities and features. It’s important to choose a system that fits your budget while meeting your testing requirements. The price of a temperature forcing system can vary depending on the factors mentioned above, so it’s crucial to carefully consider your needs and budget before making a purchase.

By leveraging temperature forcing systems and understanding their capabilities, engineers and project leads can ensure the quality, reliability, and performance of their hardware products across diverse environmental conditions.
