Analyst ems+ft - In Circuit PCB Test/Functional Test (ICT/FT) System

Analyst ems+ft - In Circuit PCB Test/Functional Test (ICT/FT) System Description:

In Circuit and Functional Test System

The CheckSum Analystems+ft is designed for testing most common circuit assemblies. It combines manufacturing defects analysis (ICT/MDA) with power-up functional test to provide extremely high fault coverage in a single, lowcost test station.

ICT/MDA testing tests the unit under test (UUT) without power applied. Using sophisticated measurement techniques such as DC and complex-impedance measurements and multi-point guarding it provides the capability to fi nd the majority of faults such as shorts, opens and wrong or incorrectly installed components. By fi nding the majority of faults while the UUT is in the safe unpowered mode, and with very specifi c fault diagnostic messages, faulty UUTs can be repaired quickly.

Once the ICT/MDA tests have successfully completed, the Analystems+ft provides the capability to power up the UUT to test for performance faults. This capability can be used to help ensure that the UUT will operate properly in its end environment, fi nding problems such as faulty ICs or other subtle performance problems.

The Analystems+ft is designed to be used for most common circuit assemblies. It can perform effective powerdown testing for most analog or digital assemblies being manufactured today. The power-up functional testing is ideally suited for lower frequency analog-type assemblies with some digital content.
