In the 1920s, the field of physics was in disarray. The reason was that many careful observations and experimental data could only be explained by conflicting theories; for example, some proved that light was a wave, while others provided it had a particle-like nature. Other experiments, such as those in black-body radiation or the photoelectric effect, could not be explained … [Read more...]

Review of FLIR’s FLIRONE PRO IR Camera
While most of my clients are most interested in EMI mitigation, a few wonder aloud about certain IC temperatures. For that reason, I carry a small IR thermometer in my troubleshooting kit. However, when FLIR announced the FLIRONE PRO module that attaches to iPhones, I was hooked and had to purchase one. The FLIRONE PRO includes a dual camera – one for infrared capture and … [Read more...]
Metal Foam Heat Exchangers
Reticulated Metal Foams (RMF) are cost-effective and ultra-high-performance thermal management materials that can be integrated with electronic devices and modules. RMFs are compatible with DI water, inert fluoro-carbons, jet fuel, and inert gases. STRUCTURE OF RMF There are quite a few ways to fabricate RMF [1], however the investment casting method of … [Read more...]
