The new Flying Probe S2 testers from SPEA have been designed for the highly demanding test requirements of today’s electronics.
At the core of the system instrumentation, the entire force/measurement unit has been placed directly on the axis. Rather than just probes flying over the board, this serves as a ‘flying tester’ able to achieve zero distance between the probe and the signal forcing/measurement. This results in faster test and very clean signals, ensuring the most accurate measurement performance.
This ATE system is based on innovative linear motors and drivers on XYZ axes: materials, motion technology and motion balance are designed to guarantee extraordinary accuracy with no change, drift or calibration required. Sticky boards and flex circuits contacting is fast and reliable, as is miniaturised device testing. Even the 008004 package (0,25 x 0,125 mm) is testable with this unit.
The flying probers also extend the range of test techniques, now including LED colour and intensity test. LED flying sensors perform the high-speed measurement of the wavelength and intensity of the light emitted by LED, in compliance with the most stringent specification. 3D laser test is another new test feature: laser flying sensors measure the UUT profile, detect tombstoning and check the height of components.
100% short-circuits are detectable with just one test per net from the first prototype, thanks to the new nodal impedance test, which provides a quality and productivity enhancement compared to the conventional short circuit test techniques.
Finally, power-on test with all the probes and HV test can be performed in addition to in-circuit test, functional test, open pin scan, boundary scan, high-resolution colour optical test. The system instrumentation is configured for 8-wire measurements.
