Advances in material development has been a significant breakthrough in technology throughout the history. Development of Composite materials is a major step in the optimization of materials. The aluminium metal matrix reinforced with Boron Carbide (B4C) particles, termed as Aluminum Metal matrix composites (AMMCs), have greater improvements in their physical, mechanical and tribological properties...
Outcomes of the self-contained spiral FCG based high voltage source testing and development are presented. The source is designed around spiral FCG with 50 mm diameter and 26 mm liner made out of aluminum alloy. The liner is filled by HE cylindrical pucks fabricated by hot casting with further stamping.
The basic situation was introduced firstly on the wheel double axis fatigue (abbreviated to WDAF) testing. Then the basic process to carry out the finite element analysis and the fatigue life prediction on the WDAF testing were introduced briefly. Subsequently, a typical wheel was taken as an example to implement the finite element fatigue life prediction for the WDAF testing of the aluminum alloy...
This paper studies two popular examples of high-speed Printed Circuit Board (PCB), portable embedded devices and industrial computers, through measurement of 10-m semi-anechoic chamber in ChungHwa Telecom Labs, and proposes some simple but practical remedies to reduce their Electromagnetic Interference (EMI). In the first example, EMI of portable embedded devices can be simply prevented by an iron...
In this paper, the effects of Al pad contamination, epoxy molding compound [biphenyl (BP) and ortho-cresol novolac (OCN)] and wire (Au and alloy) on the propensity for the interfacial degradation of wire bond in a quad flap package under high temperature storage (HTS) tests at 125degC, 150degC, and 170degC are meticulously investigated. The interfacial degradation intends to be explicated in regards...
