Flying Probe Tester
Pilot and Arieal Series
Benefits
No Fixtures
Pilot systems are real in-circuit/functional testers which do not need a “test fixture“ to interface the board to be tested. Thanks to SEICA’s best-in-class flying probe mechanics, once the test program is developed the systems are ready to contact the test points, minimizing the time needed to implement product test and consequently drastically reducing test costs.

Better Access, One coverage
Since Pilot systemscan directly access component pads without requiring dedicated test points, these systems can increase test coverage of in-circuit test programs with respect to the traditional bed-of-nails approach, providing optimum quality of the test even on today’s high-density SMT boards.

One Unique Platform
When you choose a Pilot system you do not choose just a test system, but a complete test platform; this means that you have a whole range of capabilities and performance, including in-circuit test, functional test, optical inspection, on-board programming of digital components, “vectorless“ test technologies, boundary scan test, which enable you to implement the most appropriate test strategy according to the type of product, volume, throughput, and any other specific requirements you may have.

Precise Diagnostics
Pilot systems provide precise fault diagnostics, detecting the exact fault on the board, allowing even less-experienced operators to rapidly locate the defect and to repair faulty boards.

Easy to Program
On Pilot systems program generation is completely automatic thanks to the powerful component libraries and measurement capabilities; the test of a prototype can be implemented in a matter of minutes up to only a few hours, using only a single sample and the board design CAD data.
Key features
A complete analog/digital in-circuit tester
It includes the same measurement instrumentation as the other Seica in-circuit ATE systems, which provide test of passive and active components as well as full, in-circuit test capability for analog and digital devices. All Pilot systems are also equipped with 8 additional fixed analog channels as a standard feature, expandable up to 1032, to provide more access to the UUT. An accessory bed of nails receiver is available to be connected to a Pilot, allowing the user to migrate the same test programs already developed from the flying probe tester.

A Versatile Functional Tester
It can be equipped with up to 6 user power supplies programmable in voltage and current, digital I/O cards operating up to 25 MHz, synthesized analog instrumentation based on DSP architecture.Pilot has the capability to manage standard protocols such as CAN, IEEE488, RS232 and others to integrate external instrumentation. VIVA software can communicate with external applications via .DDL libraries, allowing maximum customization of functional test, using a single test system
A Real Boundary Scan Tester
The system can test digital boundary scan components on the UUT through fixed connections, and also allows fast implementation of ”cluster” tests on mixed technology boards by using the flying probes as very flexible diagnostic tools to have access to the ”virtual” boundary scan nets.VIVA software also allows the
integration of in-circuit and functional test with boundary scan, to eliminate redundancies in order to maximize test coverage and optimize the test time.

A Simple Effective AOI system
It can inspect for component presence, absence and polarity, has OCR capability to recognize printed values and symbols, and to read 1 and 2D barcodes. The vision system on Pilot is perfectly integrated in the VIVA software along with the other electrical test tools, allowing maximum test coverage for in-circuit programs, going beyond technological limitations (i.e. parallel capacitors on a power circuit which cannot be measured individually, but can be inspected one by one with vision).

A sophisticated in-circuit on board progamming tool
Useable for programming microcontrollers, flash memories,EEPROM memories and PLD devices of
any kind. Data can be written in the digital devices either through the hardware resources integrated in the VIP platform, which include high speed, low noise digital channels, or through integration of external, off-the-shelf programmers supplied by the programmable component manufacturers.

Vectorless Techniques
OTPN
The DSP-based measurement instrumentation of the Pilot enables the test of an electronic board, executing one single measurement for each electrical node of the circuit, using the OTPN technique (One Touch Per Net).

The analysis in the frequency domain of the electrical parameters of the board is extremely sophisticated, but at the same time very simple, since it is automatically managed by the VIVA software. This technique can drastically reduce test time while maintaining a very high level of fault coverage

OPENFIX
Pilot systems can be equipped with one or more additional mobile ”OpenFix” probes, to test for unsoldered (open) pins on ICs and connectors, as well as the polarity of electrolytic capacitors. The OpenFix technique does not require any programming by user, since the measurements are simply autolearned on a sample ”golden” board.

Pilot systems can also accommodate up to 64 additional, fixed OpenFix probes which can be positioned throughout the test area using magnetic supports or dedicated jigs.

Prepare, Verify, Test

All Pilot systems are managed by the VIVA software platform, which is based on the latest technology such as the ”.NET” architecture.Test program creation is divided into three specific phases: PREPARE- VERIFY - TEST, and the user is guided through a series of automated operations in an intuitive, self-explanatory environment which drastically reduces programming time and practically eliminates errors and omissions, guaranteeing the high quality of the final test program.

The PREPARE phase includes the translation of the board CAD data into Seica format, the physical analysis of the PCB in order to place the test points for probing, the circuit analysis of the board to calculate the test coverage, the measurement methods to use, and program optimization to minimize the test time. The PREPARE phase is completely automatic, and can be carried out on the test system itself or completely offline on a remote programming station.

The VERIFY phase adjusts the measurements on one or more sample boards.This phase requires the use of the test system, but it can also be carried out in a completely automatic mode, without the presence of a dedicated ”debug” engineer, thanks to the powerful autodebug libraries included in VIVA.

During the TEST phase, the Pilot systems execute the board tests, providing test results and information on the faults found, including graphic statistical information useful during board repair and for the creation of the data base required for product traceability and certification.
