The Future of Testing


In our previous test blog posts, we looked at the history of automated test equipment for semiconductors and for printed circuit boards. This month, we look ahead to the test technologies that are emerging. The chip ATE field has essentially boiled down to Advantest, Teradyne, and Xcerra (LTX-Credence), while the board test market is dominated by Teradyne and Keysight Technologies (formerly ... » read more

Wireless Test: Too Many Protocols


Testing wireless communications is getting far more difficult as more markets begin adding wireless communications and standards groups push to improve the speed, power and security of existing protocols. There is already a long list of protocols, and it's growing further as new communications technologies are added into the mix. With the addition of 5G, the new 802.11ax standard, and other ... » read more

Looking Back at Board Test


Printed circuit board testing has been around as long as printed circuit boards, also known as printed circuit assemblies and printed wiring boards. PCB technology started in the early 20th century with Thomas Edison and other inventors. As boards shrink to fit inside wearable gadgets and other products with compact form factors, PCB test equipment vendors are addressing new challenges. Boar... » read more
