DFT Preparation

Plug-In category: Fabrication Tools Plug-In included in: PCBI Production Control


The DFT Preparation Plugin includes all necessary features for you to plan and create test programs.

So far, machines from Seica, Takaya and i3070 are supported.




The following tester types are supported:

ICT Tester (Fixture):

For ICT testers, you can automatically create needle positions with with rule-based needle sizes and minimum distances. Test points, vias or THT pins can be used as a basis.

Needle positions are created according to the set rules with the necessary minimum distances to adjacent components and towards other components.

Flying Probe (Fixtureless):

Flying Probe Testers can use test points, vias or THT pins as well as the SMD pins of the individual components. Here, the SMD pads are automatically contacted staggered externally in order to avoid damaging the components.

It is also possible to define specific short circuit tests for this system according to different rules.


For all test systems, the required number of test accesses per net can be defined, and specific individual accesses can be added or fixed manually. Of course, all automatically set accesses can also be moved or otherwise edited via drag&drop.

For each component, you can also store a test model with various parameters, such as transistor tests or potentiometer tests. These test models as well as the exact component contour can also be retrieved via e.g. EasyLogix Part Library (EPL), which makes the generation of a test program even faster and easier..

Various statistics about the test coverage help to further optimize the test program before the final machine export is generated. The DFT Preparation Plugin offers you the possibility to plan whole panels at once and with little effort..


The defined test programs can be exported for the following machines:

Seica:

The Seica export creates a package of files (.alf/.inf/.nod/.par/.sha/.shi) containing all available component and net information to easily create the test program in the VIVA Software of Seica.

Takaya:

The Takaya export creates a ".ca9" file containing a whole test program. This includes a wire analysis where parallel and serial Resistors/Capacitors/Inductors are merged if there are not enough probes to test them separately. For small value components, that get lost in the tolerance of the overall circuit, additional Vision Tests are created. The export can be done for one-sided Takaya machines as well as for two-sided ones (4 fingers on one side, 2 on the other).

i3070:

The i3070 export creates a “board” and “board_xy” file that contain all available component and net information to easily complete the test program with the native machine software.


Furthermore, there is an Excellon2 export available, which greatly simplifies the creation of a needle adapter. A test point foil can also be created automatically in PDF format.

The goal of the DFT Preparation Plugin is to easily and centrally define optimum test programs, independent of the used machine. Therefore, no expert knowledge for the respective machine software is required. In conjunction with the EasyLogix Part Library (EPL) and the test models stored there, consistently high-quality test programs are generated in the shortest possible time. These programs are ultimately output using machine-specific parameters for the respective system. The insertion side and rotation can be defined, too.
