In the electronics industry, technology leadership is key to customer satisfaction.
Peter Bigelow

Reliability Report
Slow increases in resistance during the testing suggest metal fatigue, or wear-out failure, a common failure mode for robust PCBs.
Paul Reid

Interconnect Strategies
VNA is a powerful tool for determining DUT response in frequency domain, but accuracy is influenced by external factors.
Dr. Abe Riazi

Designer's Notebook
