The increasing demand for electrical failure analysis (EFA) in yield enhancement [1] has created new challenges for foundries and their clients. Dynamic EFA techniques, more in demand with the smaller technology nodes, have largely been the domain of the design-house failure analysis (FA) lab. In 2010 on 40nm packaged parts, a new laserbased technology, laser voltage imaging (LVI) was applied t...

It is now generally accepted that wherever we need to address multiple different kinds of data deriving from multiple different kinds of sources, a strategy is required to ensure interoperability across the various systems involved. The United Nations Environmental Program (UNEP) is developing an ontology for use in their knowledge management platform—the Sustainable Development Goals Interface...

Primljeno (Received): 2011-11-07 Prihvaćeno (Accepted): 2012-03-15 Original scientific paper Abstract: Pressure die casting is the method used for forcing molten metal into mould cavities under high pressure and at high speed (10 100 m.s). Pressure die casting is a highly productive method of casting parts with low dimensions tolerance and high surface quality. From the point of view of product...

We present an innovative approach to casting process planning based on case-based reasoning. Process planning involves deciding the methods, materials and machines for various steps in manufacturing. It is an important activity that affects product cost and quality, and requires experience. Such experience can be stored using a knowledge management system, then retrieved and modified for a new ...

The purpose of the work is to evaluate the EMF levels in the surroundings of particular induction heating installations used for melting metals and some methods for mitigating them. The data from measurements in a metal foundry will be presented and discussed with reference to the limits for occupational environment. In some cases the measured levels overcome the ICNIRP limits. For these cases ...

[Purpose] This cross-sectional study aimed to compare foundry workers of the metallurgical industry with high and low exposure time and with a control group. [Subject and Methods] The workers were evaluated for pulmonary function and peak expiratory flow (PEF), respiratory symptoms, smoking habits, and physical activity level. Descriptive statistical analysis and ANOVA one-way test were used. [...

A scheduling problem for an engineer-to-order foundry that manufactures propeller blades for ships is outlined. The main objective for the foundry is to find an efficient production plan that minimizes the total number of days orders are late. This has to be done subject to a set of relatively common constraints related to the scheduling of the present jobs and resources. The constraints on the...
