4520 flying probe system

Aeroflex has released the 4520 standalone flying probe system, a quick, easy and flexible solution to meet a variety of PCB testing needs. Designed to perform high-speed, high-accuracy fixtureless test in a standalone platform, the 4520 offers users all the benefits of the popular 4550 in-line Flying Probe System, at a lower entry cost.

The 4520 standalone system combines the latest in flying probe hardware technology with innovative software techniques, shortening time-to-market with a quick program generation and flexible testing techniques.

In addition, the 4520 system is suited to reduce test costs per board in a low to medium-volume PCB manufacturing environment that does not require in-line test.

Flying probe
The 4500 Flying Probe Series is a highly flexible, fixtureless test environment that provides the level of throughput required in production on a "one-stop" test platform, but flexible enough to make it suitable for prototype applications. The 4500 Series is comprised of the 4550 in-line and the 4520 standalone test systems. Both models offer fast and highly accurate probing, short program development times, together with advanced test techniques, such as device programming, boundary scan and functional test capability.

The 4500 Series features a soft landing option to minimize potential damage to the unit under test (UUT) caused by probing, which is especially important in 'safety critical' applications common in military, automotive and medical industries. It works by allowing the probes to travel at normal speed in the Z-axis, but decelerate towards the end of their travel, avoiding potential damage to UUT.

The partial accessibility option of the 4500 Series is an automatic process that allows components to be tested, even when some of the probes cannot access specific target points due to the test subject architecture. This technique takes advantage of a further key development that enables accessibility to be maximized through the ability to automatically switch all test probe angles between 0 and 8 during program execution.

"Aeroflex is committed to moving our ATE line forward by continually introducing new products and new features to enhance capabilities, increase usability and add value for our customers," said Kevin Tomkins, ATE product manager, Aeroflex test solutions. "The new 4520 standalone flying probe system meets the stringent requirements of today's test market. Customers can count on the continued evolution of the 4550 line to ensure it will meet tomorrow's needs just as efficiently."
