Currently, the rebound hammer is widely used for estimation of compressive strength of concrete as general testing method. Although rebound hammer has made great contribution for compressive strength ...

Recently, a team led by Prof. DU Jiangfeng from the Key Laboratory of Microscale Magnetic Resonance of Chinese Academy of Sciences (CAS) developed a new method for deep electrical impedance tomography ...

The most different aspect between a normal lamination structure and High-Density Fan-out (HDFO) is the routing scale. That aspect is also the challenge and focus of this study. At an HDFO scale, most ...

These graphs compare the pressure/flow characteristics of orifice and capillary restrictors. The characteristic impedance of an orifice restrictor does not vary linearly, so it will not always match ...

Ceramic capacitors play an oversized role in circuit performance as a major contributor to voltage regulator control loop stability and power delivery network (PDN) impedance. When designing with ...

Power-hungry AI accelerators and other high-performance chips are throwing a wrench into power integrity. Learn how Picotest is trying to tackle the challenges with more advanced test probes. Voltage ...

Many articles and application notes describe the extraction of phase margin, using a non-invasive technique that extracts the phase margin from an output impedance measurement. The term non-invasive ...
