Scan technology is essential for testing the digital content of large-volume devices. By using scan, you can make the device itself responsible for some of the “test” chores, and you can shorten the ...

About a dozen years ago, the world of test had reached an economic impasse: most digital designs had become sufficiently complex that standard scan testing techniques were no longer cost-effective.

The purpose of your engine is to compress fuel and air and then ignite it, creating heat energy that then makes mechanical motion. If your engine can't compress the air and fuel properly, the engine ...

The trend in semiconductors leads to more IC test data volume, longer test times, and higher test costs. Embedded deterministic test (EDT) has continued to deliver more compression, which has been ...

A remote starter switch and a top-quality, screw-in-type compression gaugeâ such as these models from Sears, Roebuck & Companyâ can be used to measure the pumping efficiency of an engine, as well as ...

You might talk about it often, but do you really know what compression is all about? Every engine has to make it and those that don't are hurtin' for sure. But, here's the confusing part, for this ...

Test compression sounds like magic. Read on to learn how this trick is done. Large, complex ICs are viable because their design meets test as well as functional requirements. Design for test (DFT) was ...

A compression test reveals the condition of your engine's valves, its valve seats, and piston rings and whether these parts are wearing evenly. Healthy engines should have compression over 100 psi per ...

The Combined Loading Compression (CLC) test method was standardized by ASTM in 2001, as ASTM D6641 1. During the past 10 years it has become the most-used compression test method for composite ...

I noted in a 2005 column (see "Current compression test methods" under “Editor's Pick,” at top right) that there are three basic methods of loading a composite material test specimen in compression: ...
