Real-time X-ray inspection systems have been used in quality assurance applications for more than 25 years. In electronics manufacturing, for example, X-ray inspection ensures the registration of drilled holes to internal pads of multilayer printed circuit boards. In electronic assembly applications, X-ray inspection ensures the quality of hidden solder bonds of surface-mounted components such as ball-grid arrays, as seen in figure 1 below.
Now real-time X-ray inspection is becoming an important tool for ensuring the quality of many medical devices. These devices incorporate a diversity of materials, including polymers, rubbers, steel, titanium, ceramics, and glass. Real-time systems employ fluoroscopic imaging devices to display the device’s X-ray image in a video format.

Data mining methods have many origins, including drawing on insights into learning as it naturally occurs in humans (cognitive science), and advances in computer science and algorithm design on how to best detect patterns in unstructured data. Although traditional statistical methods for analyzing data, based on statistical theories and models, are now widely accepted throughout various industries, data mining methods have only been widely embraced in business for a decade or two. However, their effectiveness for root cause analysis, and for modeling, optimizing and improving complex processes, are making data mining increasingly popular--and even necessary--in many real-world discrete manufacturing, batch manufacturing, and continuous-process applications.
There is no single, generally agreed-upon definition of data mining. As a practical matter, whenever data describing a process are available, in manufacturing for example, then any systematic review of those data to identify useful patterns, correlations, trends, and so forth, could be called “data mining.” Put simply, data mining uncovers nuggets of information from a sometimes vast repository of data describing the process of interest.

Enron. Worldcom. Tyco. Cendant. Bernie Madoff, once chairman of the NASDAQ, is now cooling his heels in jail. The ex-CEO of Comverse is arrested in Namibia, the CEO at United Healthcare is forced to step down, and Patricia Dunn of Hewlett Packard is charged in an ethics scandal. And, of course, AIG has no problem doling out millions in bonuses to the very people who drove the company and the country into a financial crisis. It seems that no matter where we look today, the erosion of ethics and basic moral principles of right and wrong have taken us to the point where trust in our institutions and the very systems that make our society work are in imminent danger of oblivion. Perhaps at no time during the last two or three decades has business ethics, or the lack thereof, been of such paramount importance to the well-being of our business entities and country.
Making sure that measuring instruments are properly calibrated is critical to quality manufacturing operations. A gauge that doesn't read accurately and repeatably can compromise the integrity of quality control and quality assurance documentation, and destroy confidence in measuring results. At their worst, inaccurate gauges can result in the production of nonconforming parts.
Gauge calibration represents an important, if not fully appreciated, manufacturing discipline. It should be viewed as an investment. Gauge calibration is the foundation upon which a quality program can be built.
More than simple adjustment
Gauge calibration determines the deviation from the true value of the indication supplied by a measuring instrument. The results of the calibration process can be used for gauge adjustment. Calibration goes beyond simple adjustment, however. A calibrated gauge can be traced back to a master source. Traceability provides the value added to the calibration process.
The quality industry offers a number of terrific events during the course of the year, but none is more informative, entertaining, and intimate than the Coordinate Metrology Systems Conference. This year’s CMSC occurs in Charlotte, North Carolina, July 21 through July 25. As always, the event is packed with activity, including a bustling exhibition hall, unique off-site events (a tour of Richard Childress Racing is included this year), and white paper presentations demonstrating the latest advances in portable coordinate metrology.
Energy generation is a multifaceted industry comprising dozens of major discrete technologies and thousands of companies. For reasons that are at once political, economic, and environmental, the energy industry occupies a central place in modern human society, and it will for the foreseeable future.
Alternative energy resources, such as photovoltaic modules and wind turbines, represent a particularly fast-growing segment of the industry. This article will look at this sector from the perspective of quality assurance and safety testing, two extremely important concerns for producers, as well as consumers, of alternative energy.
Manufacturers’ efforts to do more with less have resulted in purchasing departments sourcing cheaper products and parts, often from overseas. Such cost-cutting certainly makes purchasing look good to management. But the effect on quality professionals may be just the opposite: product or part defects, malfunctions or undesirable side effects, not to mention the challenge of producing high-quality end-products within narrow timelines and budgets. Many sleepless nights are a frequent outcome.
Because cost cutting and global sourcing are here to stay, how can quality professionals combat these monumental challenges? Root cause analysis (RCA), when fully utilized, can eliminate defects in your operations as well as defects that you inherit from suppliers, ultimately helping to maintain a satisfied and engaged customer base.
Electronic records--theircreation, modification, maintenance, retrieval, and archiving--can create ongoing challenges for all organizations. For industries regulated by the U.S. Food and Drug Administration (FDA), such as pharmaceutical companies, medical device manufacturers, food processing plants, and biotech companies, the FDA’s Code of Federal Regulations Title 21 Part 11 applies to the specifications, use, and control of electronic records and electronic signatures.
The requirements of FDA 21 CFR Part 11 for electronic records are based on good practices, organization, and, most of all, common sense to ensure the efficient and secure handling of these records. In general, these requirements state that:
• All information is complete, and all records can be tracked to their originator and corresponding records.
• Appropriate securities are in place to ensure that tampering that would alter the record from its original intent does not take place.
• Only the appropriate parties can access the records, and only those so identified can create, modify, or review those records.
