30 Years of Bringing Bad News, One Board At A Time


Failure, contrary to what many may think, can be an option. Failure can even teach a great deal, especially when it results from a malfunctioning process. Datest (www.datest.com) has been in the business of testing and inspecting printed-circuit-board assemblies (PCBAs) for 30 years ...

Advanced Drop-Jet Fluxing for Selective Soldering


Many different flux chemistries are available when implementing selective soldering technology, including low pH fluxes, high-solids-content fluxes, and water-soluble, alcohol-based, or rosin-based fluxes. Just as the choice between various lead-free solder alloys is often made according ...

Boundary Scan Integration on Flying Probe Testers


In the 1980s, the electronics test industry faced challenges related to more complex, densely populated printed-circuit boards (PCBs) and more difficult access to test points. The increasingly smaller sizes of electronic devices drove the design of denser and more complex PCBs. The ...

For Electronic Assemblies, Reliability Rules


Michael Konrad (konrad@aqueoustech.com) previously served on the U.S. Navy's EMPF Manufacturers Committee in the late 1980s, and has published dozens of articles on cleaning and cleanliness testing. He is a regular speaker at industry conferences has taught cleaning and cleanliness ...

How Acoustic Microscopes Became Smart


The evolution of acoustic microscopes in recent years has enabled them to extend their nondestructive data-collecting and image-making capabilities in several directions. By doing so they have made possible new kinds of analytical and screening techniques and become smarter. The changes ...

Nortech: How ezLOAD Board Support Boosts Revenues


What happens when a highly experienced and respected EMS provider starts getting an abnormally high number of failures related to the printing process? Obviously, a solution has to be found, and implemented quickly. The failure rate had become a serious and growing problem for Wayzata ...

Scanning Electron Microscopes Expand Fields of View


Scanning electron microscopes (SEMs) are among the most exotic and, at the same time, invaluable test tools in the electronics industry. Quite simply, they are microscopes that use electrons instead of light to "illuminate" a target. They use an electron gun to produce a beam of electrons ...

Selective Soldering With Added Flexibility


Selective soldering systems provide a great deal of capability for electronic manufacturing facilities, but they also require some education to learn how to gain the maximum benefits from those systems. For a typical printed-circuit board (PCB), components to be selectively soldered ...

What's Inside That USB Drive?


Electronic products and microsystems technology can be characterized by a trend of continuing miniaturization. They are inseparably connected with miniaturization in packaging and the needs for nondestructive testing (NDT) methods. Such testing approaches support efforts to maintain ...
