Art Solutions

Una soluzione completa per la creazione dei tools necessari al test elettrico.

KerTEST importa dati da numerosi CAD, e utilizza un potente parser per estrarre i dati dalle BOM (lista materiali). La BOM definisce le parti montate e il corretto PartNumber.

KertTEST usa inoltre dati da una propria libreria dalla quale ricava la descrizione delle probe per la generazione della fixture, la descrizione per la Boundary Scan, e la Digital Library.

Configure the environment

Power Net Detector
Assign Power and ground bases on signal name. The detection may use keyword.

Part Parallel Detector
For the test measurement, it is important to compute the equivalent value of part s in parallel. This will eliminate the wrong redundancy measurement. The detection is automatic

Split component network
A specific editor, partially filled, minimize the possible mistake.

Pin map assignment
For each class of component a dedicated graphic allows the pin assignment. The user must just select the signal to the pin.

Boundary Scan assignment
The user select in the library the corresponding BSDL description and get the test condition.

Digital assignement
The user select in the library the corresponding digital model description.

Optimize the probe quantity and placement.

Boundary Scan
Kertest do a full analysis of the board to define the best probe placement and optimize the quantity of probe required for the maximum fault coverage. In case of boundary scan Kertest determines if a boundary node require having a probe or not. At the end a log report is generated and a full status of each node is displayed. At this level a list of required probe is used by the physical probe placement.

Probe Placement
A Step by step method, to check at each level, the condition and create a report. That mean if there is an error, it could be corrected immediately and not wait the end of the process.

• Step1 is the generation of the keep out area of each side of the board, including the area for gasket or conveyor slide
• Step2 defines the priority level, the is a choice of 100 possibilities.
• Step3 defines the quantity of probe per net. This step is using the result of Boundary Scan testability
• Step4 defines the type of probe to use; the data are extracted from Probe Library.
• Step5 defines the probe placement depending of the physical distance between probes. An editor displays the result with one color per probe type.
• Step6 defines the data required to generate the fixture. The board is placed on tester plate and specific editor allows adding tool pin, spacer, spring and pushrod.

A final report describes the test quality level.
