With its long-term industry experience, Eldig holds courses to share its know-how on board testability, project methodologies, functional tests, etc.

More than thirty years of experience enable Eldig to constantly develop its know-how and impart it on a theoretical and practical level.
This is why Eldig provides not only ATE consulting services, but also holds training courses that are fully customisable to cater for customer needs. Based on two main areas, explained below, courses can be tailor-made to cater for customer companies’ actual needs, in terms of duration, venue, content, focus, methodology (theoretical or practical), material, number and target of participants, etc.

In particular, our training courses comprise:

COURSE on TESTABILITY and PROJECT METHODOLOGIES

All electronics manufacturers have to test their products. Companies may already have programmable testing equipment, such as our AFT system, or may have to acquire adequate instruments.
If testing is considered when designing new boards or finished equipment, testing performance can come close to 100% of functions.
So two different scenarios are possible: new boards or finished equipment.

In the first case and based on the considerations above, Eldig has designed a course to explain the benefits of testing boards with ATE ICT as level-one testing, immediately after assembling and welding components.
The course illustrates the measures necessary at a design level to ensure that most components may be tested, and the technical measures required to correctly perform tests.
Providing for a test point often costs little or nothing during the circuit design and development stages, and exponentially increases testability at a testing level.
Test equipment must make contact with the circuit and, if this is not possible, testability is reduced as the circuit can never be measurable alone.

As regards finished equipment, functional testing as production output is essential to determine the quality level of the product and all its functions. The designer must consider testing, so that all circuits concerned can be easily accessed. 
Eldig’s course explains the methodologies and techniques necessary to ensure a high level of testability and diagnostics in functional testing.

In a final practical session, a real board or project in the advanced stages are examined, to correctly apply the course content learnt.
In this case, company technicians attending the course will examine, and correct the design if necessary, to make equipment testable, supervised by our trainer.

As already mentioned, the course can be tailor-made to cater to the customer company’s needs: the duration can be customised, as well as the venue (at Eldig testing or at the customer company’s facility), the content (calibrating content based on production and customer case histories), the focus, methodology (more theoretical or more practical, with a significant part dedicated to application if necessary), material, number and target of participants (a small or large number, designers or quality operators), etc.

COURSE on FUNCTIONAL TESTING for the AFT line

The purpose of this second type of course is to acquire basic techniques to perform functional testing, particularly on our ATE, AFT line.

The first part explains the techniques used to correctly establish that the product has been tested as far as possible to 100% on leaving the factory.

Functional testing, unlike in-circuit testing, does not test the individual component, but the global functions of the device in terms of how it has been designed and therefore its intended end use.
For example, on a telephone, functional testing does not test the individual condensers, resistances or integrated circuits, but instead tests for the line signal when the receiver is lifted, for communication, etc. 
The equipment used to perform functional testing (such as our AFT systems), must provide for loads, stimulation, measurements, etc. 
This course explains the techniques necessary to achieve maximum testability of all designed functions. Design is a very important part, as it must allow for the testing engineer to perform functional tests on equipment, so as to achieve the objective of maximum testability.
The devices to test nearly always have microprocessors with memories in which the programme (firmware) to run during testing is installed.
The designer must pay particular attention to running this testing firmware and this course explains correct techniques to achieve maximum efficiency.

The second part of the course concerns our ATE, AFT lines, and explains how functional testing is performed, at both a theoretical and practical level, with functional tests written and performed on actual boards.

The third part provides full instructions on how to use our AFT line, explaining all functions, and including practical sessions with participants developing tests, supervised by our trainers.
