 Aeroflex's 4550 flying probe test system

Aeroflex has added soft landing and partial accessibility software options to its 4550 flying probe test system for PCB testing.

The probe soft landing option is said to minimize potential damage to the unit-under-test (UUT) caused by probing, which is 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 is an automatic process for the 4550 that allows components to be tested, even when some of the probes cannot access specific target points due to component heights. The program development software will now create a test if as few as two probes have access. This technique takes advantage of a further key development that enables accessibility to be maximized via switching probe angles between 0 and 8 during program execution.

The test system is a highly flexible, fixtureless test environment providing a "one-stop" test platform suited for prototype applications. It also provides the level of throughput required in a production environment.

Aeroflex claims that the new 4550 product is both 30 percent faster and lower in cost than the previous generation 4500 model. The faster probing speed results in greatly improved testing throughput and is achieved without compromising probing accuracy and repeatability or the high levels of test coverage made possible by targeting access points down to 75?m.
