APRIL 2020 I DESIGN007 MAGAZINE 61 5. How do I know if my thermal management is a success? You will know your thermal manage- ment process has been successful when you see improved efficiency of heat trans- fer, reduced thermal resistance, and a low- er temperature observed around the heat- generating component/device. Effective- ly, the chosen thermal dissipation media will operate within the temperature lim- its defined for the device, whilst maintain- ing performance during changeable con- ditions. Conclusion Efficient thermal management is an es- sential part of both modern and future electronics design, particularly given the ongoing trend for product miniaturisation coupled with higher-powered devices. With so many different types of TIM at your disposal, it can be overwhelming to determine the correct thermal interface material for your application. But by care- ful consideration and identifying the cor- rect test regimes, it is possible to differen- tiate between products and select the most suitable material for your application. At Electrolube, we regularly assist cus- tomers with thermal interface questions to help them maximise their heat transfer efficiency. If you are in any doubt, con- tact your material vendor or us. I hope this month's top tips for TIMs have been informative. Please watch for my next column where I will examine thermal management issues further.

Bosch Develops Rapid Test for COVID-19 The coronavirus SARS-CoV-2 is posing major challeng- es for healthcare systems and medical institutions world- wide. An ability to rapidly diagnose the virus is of invalu- able help in curbing its exponential spread in many coun- tries. Bosch's new, fully automated rapid test for COVID-19 can help medical facilities such as doctors' offices, hos- pitals, laboratories, and health centers make fast diagno- ses. The rapid molecular diagnostic test runs on the Viva- lytic analysis device from Bosch Healthcare Solutions. Developed in just six weeks, the rapid test can detect a SARS-CoV-2 coronavirus infection in patients in under two and a half hours—measured from the time the sample is taken to the time the result arrives. Another advantage of the rapid test is that it can be performed directly at the point of care. It also means patients quickly gain certain- ty about their state of health while allowing infected indi- viduals to be identified and isolated immediately. With the tests currently in use, patients must usually wait one to two days for a result. A Bosch Vivalytic analyzer can perform up to ten tests in the space of 24 hours. This means it takes just 100 de- vices to evaluate up to 1,000 tests per day. Given the dy- namic spread of the coronavirus SARS-CoV-2, laboratories are already working beyond capacity. The Bosch Vivalytic will thus help to increase available testing capacities. (Source: Bosch)
