DFT Optimization

EECraftsman technical team members provide customers with DFT for design for testing, EECraftsman not only as a technology, in a sense, it is an idea, we integrate it into all aspects of product design. The DFT services provided by EECraftsman technical team members are designed to enable customers to identify product problems as early as possible, find design vulnerabilities, and help products get to market quickly.

 

With the improvement of the integration of electronic circuits, circuits become more complex, and the manpower and time required to complete a circuit test become very large. In order to save testing time, in addition to adopting advanced testing methods, another method is to improve the testability of the design itself. Among them, testability includes two aspects: one is controllability, that is, in order to detect the target fault or defect, can easily apply the test vector; The other is observability, which refers to whether the test results of the circuit system are easy to observe.

EECraftsman technical team members offer DFT solutions that include:

1, In the PCB board power supply, key signal transmission path, design test points;

2, Making the board easy to test by inserting various hardware logic modules used to improve the testability (including controllability and observability) of the board at the beginning of the original electronic design;

3, Providing board card special test tooling;

4. Providing circuit board design services dedicated to testing.
