Techniques for Suspect/Counterfeit EEE Parts Detection by Netlist Assurance Test Methods

2016-02-15
WIP
AS6171/16
Netlist Assurance Test Methods exist to assess microcircuit designs for maliciously added, removed, or modified functions detrimental to system operation. In the context of the Microcircuit fabrication design process, these methods will be used to analyze a computer aided design (CAD) representation of the microcircuit. The Netlist Assurance Test Methods discover vulnerabilities, undisclosed functions (e.g. "kill switch", paths to leak passwords, or triggers of malicious activity) and changes from the original specifications of the devices. These methods are intended to be used with standard verification methods that the implemented design has remained unchanged through the many transformations in the design flow.

In order to reduce the volume of waste in general and of shredder waste from the disposal of scrap cars, the German Federal Government has prepared a draft regulation, which will be implemented unless the automotive industry and the distributors of imported cars take action on their own to achieve these objectives. The regulation provides that the car manufacturers are fully responsible for the environmentally controlled disposal of scrap cars. The return of scrap cars to the work industry must be free of change for the last owner. A nation-wide network for the return of scrap cars must be implemented by end of 1993. To reduce the amount of shredder waste the automotive industry is expected to practice recycling on non-metallic materials. Facilities required for thermal treatment of residues, which cannot be recycled, are to be installed on account of the originator, i.e. the automotive industry.

91A117
Mold designers and foundrymen spend a lot of time in developing molds without knowing exactly the phenomena which take place inside. Simulor, which has been used in an industrial environment for two years, offers the solution to make foundrymen understand what happens during the filling of the mold and the solidification of the part. Based on navier-stokes and heat transfer equations, simulor provides speed distribution and metal front evolution in the cavity and thermal map in the mold and the part. Some examples with different metals (cast iron, aluminum alloy) cast with various processes (sand or die casting, low pressure or gravity casting) will be given. This new tool will given foundrymen the opportunity to test the mold before having it machined and will also allow reduction in development delays.

Particulate Reinforced Aluminum Matrix Composites Obtained By Indirect Squeeze-Casting

1996-04-01
91A115
Indirect squeeze casting technology is one of the most attractive fabrication techniques of near net shape components constituted by aluminum matrix composite (AMC) materials. AMCs reinforced with both continuous and discontinuous ceramic elements have been mainly produced by infiltration of porous preforms. Nevertheless, a further promising production route offered by this technique is given by the possibility to employ ingots of pre-reinforced aluminum alloys containing ceramic particles (silicon carbide or alumina); ingots are remelted and, under suitable operative conditions, high quality composite castings of simple and complex shape are produced by squeeze casting. The present paper describes the results of an extensive experimental work carried out by Alures-Centro Tecnico Porcessi on a pilot plant scale employing a vertical squeeze casting machine with a clamping force of 315 tons.

Manufacture of Automotive Components By Semi-Liquid Forming Process

1996-04-01
91A113
Semi-liquid forming process, applied to pressure die-casting, permits to obtain low cost components with high qualitative characteristics and adequate mechanical performances. The technology is based on the employment of material with globular microstructure (flow-cast alloys) obtained subjecting a metal alloy at the time of solidification to an elevated shear rate. Such microstructure permits the accomplishment of conventional forming processes at temperatures in solidification range. The particular fluid-dynamic properties of the semi-liquid slurry and the lower injection temperature allow to obtain casting with improved soundness, without need of impregnation, and to extend die life. The present work describes the Weber (Magneti Marelli) activity of the process industrialization and some applications for the manufacture of automotive components.

Squeak and Rattle - State of the Art and Beyond

1999-05-17
1999-01-1728
Modern trends in noise control engineering have subjected the automobile to the “drained swamp” syndrome. Squeaks and rattles (S&R) have surfaced as major concerns. Customers increasingly perceive S&R as direct indicators of vehicle build quality and durability. The high profile nature of S&R has led manufacturers to formulate numerous specifications for assemblies and components. Even so, a large majority of buzz, squeak and rattle (BSR) issues are identified very late in the production cycle, some often after the vehicle is launched. Traditionally, the “find-and-fix” approach is widely adopted, leading to extensive BSR warranty bills. The “design-right-the-first-time” approach must replace the “find-and-fix” approach. Due to the vast breadth and depth of S&R issues, a comprehensive summary of the present state of the art is essential. This paper includes a literature survey of the current state of the art of S&R, and discusses the methods available to further advance it.
