Seica flying probe system eases PCB test programming

Seica SpA announced a new addition to its line of flying probe test systems, Aerial, to address the growing demand to provide cost-effective test solutions that will further enhance ease of programming, high fault coverage and fast throughput for PCB test.

Aerial is based on the core hardware and software of the VIVA Integrated Platform (VIP) and uses four completely independent, mobile test probes to carry out tests on both sides of the board under test (two on each side). It is particularly indicated for testing prototypes, samples, small and medium series, providing maximum flexibility of use to reduce the time and costs of board development. According to the company, the vertical, very compact structure of Aerial M4 makes it easy to load and test even very large boards (up to 610-by-610mm in the L4 version), while its innovative clamping system ensures that there is virtually no vibration or oscillation of the board during test for maximum probing efficiency.

As the standard electrical test, Aerial uses Seica's proprietary one touch per net (OTPN) technique: multi-tone signals are injected through the nets of the UUT and the results are analyzed with fast fourier transforms to characterize the net and identify faults on subsequent boards to be tested. Other tests, for example verification of junction faults, are also executed during the same OTPN. In this way test program generation is simple and immediate, fault coverage is high and throughput is maximized.

"Aerial represents a simple, immediate solution to those customers who need to implement a test strategy that is cost-effective and is very easy to program and operate, even for non-specialized personnel," said Seica President Antonio Grassino.

The Aerial system is provided with data collection and statistics functions, and, since it is based on VIP technology, it is fully compatible with the other members of the Seica family (Pilot Flying Probe, Strategy In-circuit and Valid functional testers). Options include in-circuit test and visual inspection software modules.
