Counterfeit Electronic Components
Counterfeit electronic components are electronic parts whose origin or quality is deliberately misrepresented. Counterfeiting of electronic components can infringe the legitimate producer's trademark rights. Because counterfeit parts often have inferior specifications and/or quality, they may represent a hazard if incorporated into critical systems such as aircraft navigation, life support, military equipment, or space vehicles. The marketing of electronic components has been commoditized, making it easier for the counterfeiter to introduce substandard and counterfeit devices into the supply chain. Supply chain for electronic components *OCM (Original Component Manufacturers): Companies that design, market, and manufacture individual components *Franchise Distributor: Companies that are authorized to sell OCM material, governed by contracts. *Independent Distributor: Commonly known as electronic component "Brokers" *Wholesale Distributor: Companies that speculatively purchase exces ...

Counterfeit
To counterfeit means to imitate something authentic, with the intent to steal, destroy, or replace the original, for use in illegal transactions, or otherwise to deceive individuals into believing that the fake is of equal or greater value than the real thing. Counterfeit products are fakes or unauthorized replicas of the real product. Counterfeit products are often produced with the intent to take advantage of the superior value of the imitated product. The word ''counterfeit'' frequently describes both the forgeries of currency and documents as well as the imitations of items such as clothing, handbags, shoes, pharmaceuticals, automobile parts, unapproved aircraft parts (which have caused many accidents), watches, electronics and electronic parts, software, works of art, toys, and movies. Counterfeit products tend to have fake company logos and brands, which results in patent or trademark infringement in the case of goods. They also have a reputation for being lower quality, ...

Counterfeit Consumer Goods
Counterfeit consumer goods (or counterfeit and fraudulent, suspect items - CFSI) are goods, often of inferior quality, made or sold under another's brand name without the brand owner's authorization. Sellers of such goods may infringe on either the trademark, patent or copyright of the brand owner by passing off its goods as made by the brand owner.Chaudhry, Peggy E., Zimmerman, Alan.

Capacitor Plague
The capacitor plague was a problem related to a higher-than-expected failure rate of non-solid aluminium electrolytic capacitors, between 1999 and 2007, especially those from some Taiwanese manufacturers, due to faulty electrolyte composition that caused corrosion accompanied by gas generation, often rupturing the case of the capacitor from the build-up of pressure. High failure rates occurred in many well-known brands of electronics, and were particularly evident in motherboards, video cards, and power supplies of personal computers. A 2003 article in ''The Independent'' claimed that the cause of the faulty capacitors was in fact due to a mis-copied formula. In 2001, a scientist working in the Rubycon Corporation in Japan stole a mis-copied formula for capacitors' electrolytes. He then took the faulty formula to the Luminous Town Electric company in China, where he had previously been employed. In the same year, the scientist's staff left China, stealing again the mis-copied f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quality Management
Quality management ensures that an organization, product or service consistently functions well. It has four main components: quality planning, quality assurance, quality control and quality improvement. Quality management is focused not only on product and service quality, but also on the means to achieve it. Quality management, therefore, uses quality assurance and control of processes as well as products to achieve more consistent quality. Quality control is also part of quality management. What a customer wants and is willing to pay for it, determines quality. It is a written or unwritten commitment to a known or unknown consumer in the market. Quality can be defined as how well the product performs its intended function. Evolution Quality management is a recent phenomenon but important for an organization. Civilizations that supported the arts and crafts allowed clients to choose goods meeting higher quality standards than normal goods. In societies where arts and crafts ...

Solderability
The solderability of a substrate is a measure of the ease with which a soldered joint can be made to that material. Good solderability requires wetting (low contact angle) of the substrate by the solder. __TOC__ Of metals Solderability varies depending on the type of solder alloy under discussion. The discussion that follows applies only to unspecified electronic solders (which may include solders that contain lead, now banned for use in nearly all electronic equipment made or sold in the EU). Solderability when using lead-free alloys can differ significantly from solderability when using lead based alloys. Noble metals may be easy to solder but they have brittle joints. The metals in the good category require a large amount of heat therefore oxidation is an issue. To overcome this a flux is required. For carbon steel, low alloy steel, zinc, and nickel the presence of sulfur creates a brittle joint; lower temperatures are used to minimize this problem. The oxides on the surface of ...

Stereo Microscope
The stereo, stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly different viewing angles to the left and right eyes. This arrangement produces a three-dimensional visualization of the sample being examined."Introduction to Stereomicroscopy" by Paul E. Nothnagle, William Chambers, and , '' |

Scanning Acoustic Microscope
A scanning acoustic microscope (SAM) is a device which uses focused sound to investigate, measure, or image an object (a process called scanning acoustic tomography). It is commonly used in failure analysis and non-destructive evaluation. It also has applications in biological and medical research. The semiconductor industry has found the SAM useful in detecting voids, cracks, and delaminations within microelectronic packages. History The first scanning acoustic microscope (SAM), with a 50 MHz ultrasonic lens, was developed in 1974 by R. A. Lemons and C. F. Quate at the Microwave Laboratory of Stanford University. In the late seventies and early eighties acoustic microscopes operating in several GHz range were common place and a transmission SAM operating up to 500MHz had also been made by R.Gr. Maev and his students at his Laboratory of Biophysical Introscopy of the Russian Academy of Sciences. First commercial SAM ELSAM, with a broad frequency range from 100 MHz up ...

X-ray Fluorescence Spectroscopy
X-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science, archaeology and art objects such as paintings. Underlying physics When materials are exposed to short-wavelength X-rays or to gamma rays, ionization of their component atoms may take place. Ionization consists of the ejection of one or more electrons from the atom, and may occur if the atom is exposed to radiation with an energy greater than its ionization energy. X-rays and gamma rays can be energetic enough to expel tightly held electrons from the inner orbitals of the atom. The removal of an electron in this way makes the electronic structure of the atom unstable, and electr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RoHS
The Restriction of Hazardous Substances Directive 2002/95/EC (RoHS 1), short for Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment, was adopted in February 2003 by the European Union. The initiative was to prevent an overabundance of chemicals in electronics. Thus, as a result electronics were restricted. The RoHS 1 directive took effect on 1 July 2006, and is required to be enforced and became a law in each member state. This directive restricts (with exceptions) the use of ten hazardous materials in the manufacture of various types of electronic and electrical equipment. In addition to the exceptions, there are exclusions for products such as solar panels. It is closely linked with the Waste Electrical and Electronic Equipment Directive (WEEE) 2002/96/EC (now superseded) which sets collection, recycling and recovery targets for electrical goods and is part of a legislative initiative to solve the problem of h ...
