ATE

ATE (Automatic Test Equipment) refers to all automatic testing systems, i.e. devices used to test electronic boards or any production output in automatic mode.

AFT

The AFT, with its digital and analog versions, is a highly versatile, modular system for the functional testing of any type of equipment or electronic board.

EV

Eldig Vision meets two fundamental needs: testing for components assembled on electronic boards and combining this with functional testing.

EJT

EJT is a testing system for boards with a JTAG port that allows for the testing of an electronic component or chain of components, and to programme them using Boundary Scanning.

This type of equipment offers numerous benefits:

  • Absolute objectivity in evaluating the accuracy of the apparatus being tested, which is very difficult to achieve with human senses only
  • A significant reduction in the cost of the finished product
  • Speeding up the production output testing process
  • Saving on the work of specialised technicians
  • Automation in testing those products that would be impossible or too expensive to test manually

The tests on ATE of the electronic boards take place at different times of the production cycle and are extremely different, according to the production phase. Essentially, there are two types of test being carried out: the first of the tests on ATE takes place immediately after the assembly of the components on the board and the related welding. This is basically necessary to identify:

  • Presence of the components and related layout
  • Any short-circuits due to defective welding
  • Correct parameters of the various components
  • Function of the integrated, hybrid, operational circuits, etc.

The last test on ATE of the board is required to simulate the use conditions and test their functions.
Within the ATE panorama, again for electronic boards, a long-standing dualism persists among experts, placing functional testing against in-circuit type testing. Nevertheless, it is worth remembering that functional testing is essentially based on the check that the plate works correctly, without stress for the components, while the in-circuit type testing is carried out through the check of the accuracy of the assembly of each component assembled on the plate.
The Eldig testing products can perform both checks with sophisticated, easy-to-use applications.
Another fundamental subject is the “cost of testing”. This means the sum of at least four factors:

  • The cost of personnel
  • The time to identify the fault
  • The cost of the devices
  • The cost of programming the tester

Each of these components may not be considered to be independent from the others since, for example, the professionalism of the personnel in the testing activity is linked to the type of equipment used.

Eldig’s proposal has advantages for each of these factors and respectively:

  • Using Eldig testing equipment in companies does not mean retraining the workforce
  • The ease and speed of arrangement of the test set up means reducing the overall time required to identify the faults
  • The limited costs make Eldig equipment decidedly competitive in the market and easy to use
  • Due to the special features of the Eldig testing proprietary software, Customers do not need a phase to learn languages and/or platforms as it is based actually on wizards
