Listen Inc. Algorithm Accurately Measures Free Field Response without an Anechoic Chamber

During the COVID-19 Pandemic, many engineers are forced to work at home without the availability of an anechoic chamber. Listen have re-introduced an algorithm for their SoundCheck software that allows engineers to accurately measure speaker response by splicing the near-field bass response with a time windowed far field response. Results are extremely accurate. The algorithm is based on an AES paper co-written by Steve Temme of Listen Inc. www.listeninc.com This Month’s Voice Coil Magazine features an article explaining the concept,…

Simple Aperture Mod to Minimize QFN Voiding

Stop Tweaking Ground Pad Prints; Start Tweaking I/O Prints. Would you believe QFN ground pad voids could be cut by over 50% with a zero-cost, super-simple stencil aperture modification? Not a mod to the ground pad apertures where the voiding is problematic, just to the I/O apertures? Neither did we. That’s why we did some deeper digging into what we are now calling the “AIM I/O” aperture modification before introducing it. In our Tech Tips, we reported a dramatic reduction…

ASM Industry 4.0 Webinar – Sep 15, 2020 at 11:00 AM EDT

Industry 4.0 and Smart Factory are in many ways synonymous. It is a subject that companies around the world are discussing, analyzing and working to implement…food production, paper and plastics factories, cars, airplanes…and of course electronics and SMT.Rarely is a true Industry 4.0 Smart Factory started as a greenfield factory or from a clean sheet of paper. It is usually a factory that is already in place and running for many years. Moving that existing factory towards automation and Industry…

COVID-19 and the Effect on the ISOPROPYL ALCOHOL SUPPLY CHAIN

The increasing demand for sanitizers during the COVID-19 crisis has put significant pressure on the global supply chain for isopropanol (IPA). As such, the cost of the material has rapidly risen by approximately 40% and the lead time has increased. So far, Comtree and it’s customers have been unaffected by lead time as we are still able to retain stock in our warehouse. Unfortunately, the price has increased substantially. Perhaps it is time to have a closer look into IPA…
