Electronic Component Testing: A Non-Contact Sport

The smaller and more powerful an electronic device becomes, the more damage can be caused from its inherent heat. Designers are continuously looking for ways to keep components cool while maintaining the quality and integrity of performance. This article explains how thermal cameras are used in thermal management to contribute to advancements in circuit board design.

Infrared Camera Accuracy And Uncertainty In Plain Language

Trusting measurements from instruments can be difficult without a clear understanding of how the sensitivity and accuracy is derived. Many times, infrared camera measurement accuracy is confusing and can involve misleading jargon. Researchers who don’t understand these complex terms sometimes avoid the tools altogether and miss out on potential advantages of thermal measurement for R&D applications. This article strips away the technical terms and explains measurement uncertainty in plain language.

Temperature Guns Versus Thermal Imaging Technology

Common tools for non-contact temperature measurements include both thermal imaging cameras and spot pyrometers. Each works by detecting infrared radiation and translating it into temperature readings. Thermal cameras, however, have several advantages compared to spot pyrometers, including image generation, temperature readings of each pixel of the entire image, and temperature readings from a longer distance.

Benchtop Thermal Imaging: A Simple-To-Use, Cost-Effective Solution For Troubleshooting Complex Circuit Boards

Electronic products used in aerospace applications and for scientific research have two key requirements: high performance and the reliability to withstand intense environments. To attain that performance, electronics designers often use small parts and routinely push them to their limits. This article explores how benchtop thermal imaging can be used to detect design flaws and help shorten product development times.

IR Thermography – How It Works

Although infrared radiation (IR) is not detectable by the human eye, an IR camera can convert it to a visual image that depicts thermal variations across an object or scene. Thermography is a type of imaging that is accomplished with an IR camera calibrated to display temperature values across an object or scene. This article dives into the science and mathematics to explain how non-contact measurements of an object’s temperature are possible.
