Aircraft Engine Control System

CASE STUDY: Aircraft Engine Control System Compact and flexible solution also reduced costs The customer had an aircraft engine control system common to several engine platforms.  The control system monitored and controlled RPM, temperature, vibration, cycles, position, and other critical parameters to optimize engine performance.  The control system was comprised of several sensor boards and […]

Turn COTS ICs into High-Reliability ICs

Introducing a technical paper demonstrating an internal study conducted by ISI Addressing Market Needs to Withstand High Thermal Cycling Many leading-edge semiconductor device packages are designed for mass-market consumer products, like smartphones, tablets, and wearable technology. While these packages are cost-effective and sufficiently capable for consumer electronics, they are inadequate for harsh environmental applications. For […]
