 Leonardo Express
 System Operating System

Make it simple.
Get your test program in less
than 1/2 hour.

Rapid Test Development

 
Friendly graphic interfaces, and automatic functions for test program generation and debug. Leonardo Express guides you in the development and debug of test programs very quickly. Even if you are a novice in the test field.

 Features back    Minimize

Leonardo Express is the new system’s operating system for the SPEA flying probe and bed-of-nails testers. It is especially designed for non-expert users, to quickly generate a test program also for complex boards with thousands of nets.

The test program generation requires only a few simple and intuitive settings, that can be done by anyone. All the steps – CAD import and elaboration, testability and accessibility analysis, test program generation – are implemented in a guided procedure with the same instrument set, that is integrated in a graphic interface minimizing the learning curve and the time required for Test Program Development + Debug. Friendly menus, customizable toolbars and online help make Leonardo Express extremely easy-to-use.

The generated program is able to detect, quickly and accurately, all the defects which typically occur in the board producti on process, such as malfuncti oning or missing components, assembly faults, faulty or missing soldiering (open pins), short circuits. It is then possible to integrate the test program with specifi c tests through simple guided operati ons, in order to enhance the test coverage.

For SPEA Flying Probe & Bed-of-Nails Testers.

 1. Start Settings
First step. Leonardo Express provides an easy and friendly environment for the definition of the test guidelines. With these simple data, combined with the information about the used tester, Leonardo Express automatically identifies the best test strategy for the product.

2. Input Files
Leonardo Express accepts data from a variety of sources: CAD, Bill of Materials, file Gerber, etc.

3. Board Data Inspection
With Leonardo Express, you do not need to “debug” the input files before the data import. The Board Data Inspection allows the use of incomplete input files, making it easy the completion of missing information, the check of polarized devices orientation, the definition of internal parts and power supply nets.

4. Board Positioner
To guide you in the choice of the best board positioning, Leonardo Express simulates all the possible positions of the board on the tester. For each of them, it calculates the real probe accessibility for both sides of the board.
During this phase, the boards mounted on panels are identified, and the Fly Restriction Zones are easily defined by an intuitive graphical editor.

5. Test Program Generation
The test program is generated in less than 5 minutes. The automatic test program generator analyses the circuit descriptions and generates the test for all the components on the board. Leonardo Express’ expert system includes algorithms and libraries that are the result of more-than-30-year experience in test. Programs are stable
and reliable even if you have minimal knowledge in the test field.

6. Tester
Once on the tester, Leonardo Express automatically identifies the fiducial marks for the board: you just have to confirm and acquire the proposed models.
On flying probe testers, the Test Point Debug per case performed through the image acquisition of each case allows a 90% ti me saving on the check of test points, and can also be performed off-line.
Leonardo Express provides powerful AutoDebug and AutoTuning features. The unattended AutoDebug executes all the operations to correct the false Fail tests. At the end of the AutoDebug, the test program is ready for the production test. The user-friendly AutoTuning tools are used to further refine the test program, enhancing measurement stability (Cp and Cpk) while reducing the test time.
