The Keysight nanoVTEP probe (E4333A) is the latest vectorless test solution from Keysight. The entire hardware assembly, including amplifier, has been miniaturized into a single probe, capable of performing vectorless testing on devices with a geometric outline as small as 4x4mm.
PCBAs in a fixture undergoing in-circuit test have hundreds, and up to thousands of test probes pressed against their electrical contact points. This generates a substantial amount of mechanical stress that is being countered by installing pressure fingers onto the fixture to minimize board flexing.
With denser board layouts, test engineers find it increasingly challenging to have sufficient clearance within the fixture to implement vectorless test techniques that detect open signal pins with capacitive coupling through a sensor plate.
Developed with advanced manufacturing techniques, Keysight’s nanoVTEP is 60% smaller compared to existing solutions in the market. Its small profile increases the opportunity to implement vectorless testing in a high-density fixture, thereby increasing coverage and fault detection rate in the test process
