Is DFT analysis needed? When do we use it and what information does it provide?

DFT (Design for Testing) analysis is used in the process of designing and manufacturing electronics circuits. Some of integrated circuits are equipped with additional functions that make it easy to test the product for performance. DFT techniques have been developed since the 1940s. Gradual computerization made it possible to significantly improve the addition of functions facilitating the supervision and verification of the efficient operation of electromechanical devices.

What possibilities does DFT analysis offer us?

Integrated circuits are equipped with additional functions cooperating with dedicated control software. In this way, the engineer supervising the operation of the device can check its operation at any time and find any faults. Importantly, the test results are saved, which allows you to quickly locate the source of the problem. DFT analysis makes it possible to check the efficiency of the systems not only at the production stage but also during customer exploitation.

 

 

 

How is DFT Analysis used?

The new electromechanical product is subject to restrictive standards and requirements. The implementation of the product on the market requires specialized tests. DFT functions implemented at the stage of designing the system allow to shorten the time needed to verify the efficiency of the system. Manufacturers have specialized equipment and apparatus that allow them to supervise the operation of the device. This is possible thanks to sensors and functions that provide information about specific operating parameters.

What information does DFT analysis provide?

The basic assumptions of DFT analysis are based on structural tests, which differ significantly from functional tests. The functional test allows you to determine whether a given product performs its role while maintaining the efficiency of the system. Meanwhile, structural tests verify the operation of individual components. Every smallest detail on the PCB is checked. The DFT analysis quickly provides detailed information on what is happening inside the device. The results allow you to track potential failures that cannot be shown by e.g. functional tests.

Why is DFT analysis performed?

While functional tests allow to assess whether an integrated circuit is working properly at a given moment, structural tests allow to assess whether this correct operation will be maintained in the future. DFT analysis allows to track possible irregularities within the smallest elements. Eliminating them reduces the risk of product failure.

To sum up, specialized DFT analysis allows manufacturers more precise quality control and eliminates defects that could arise in the future. In this way, companies are able to provide their customers with high-quality and failure-free products. Reliable DFT analysis also allows you to improve the mass production process and reduce its costs. All thanks to the effective and convenient diagnosis of integrated circuits.

 

Cable harnesses are present in every electronic equipment that we use in everyday life. It is thanks to them that the electric current can pass from ...
The demand for electronics production services is increasing every year. This resulted in very rapid development of EMS services. What led to this? What caused such rapid development of EMS services?
The quality of cable harnesses not only plays a key role in the process of device production but also is pivotal for the reputation of the producer’s brand. That’s why great importance is attached to make sure that the companies which produce them are specialised.
Wave soldering with using hot nitrogen is a relatively young process that was introduced about 20 years ago. Initially, manufacturers rarely used this method. Today,...
