Seica Flying probe

JTAG Technologies has a long-standing partnership with Seica Spa, Italy with whom we developed one of the earliest flying-probe and boundary-scan test integrations. For the execution of boundary-scan applications with their latest generation of flying probe testers – the Pilot Next> Series –  the compact  JT 3703/USB boundary-scan controller together with the JT 2118 I/O module can be integrated into the probers.

The JT 3703/USB can be mounted on Seica’s FlyPod for “close-to the probe” integration to contact the TAP signals on manufacturing test targets or UUTs (Unit Under Test). The I/O channels of the JT 2118 module are connected  to individual flying probes to provide auxiliary test signals to improve the test coverage on UUTs. By connecting I/O probes to a UUTs external connections or test points boundary-scan test developers can improve test coverage by increasing the drive/sense points and create tests that may not have been possible using just the on-board JTAG/boundary-scan resources. Examples include tests for open circuit faults on connectors, in-system device programming  or additional logic cluster tests.

The boundary-scan applications are developed with JTAG Technologies ProVision which in addition to the netlist and BOM data of a board, now also reads information about the test points accessible by the flying prober. While the tests are run from Seica’s Viva Next> software at run-time,  Provision can take control of the probes during application debug/validation to speed-up this process.

  • Combined test report
  • Only one production step
  • Simplified or no fixture
  • Low to medium volume production
  • Boundary-scan testing: infra, interconnections, memory connections, clusters
  • Combined testing with probes and boundary-scan
  • Flash programming
  • PLD Programming
  • Four Test Access Ports (TAPs)
  • 35MHz TCK maximum clock speed
  • USB or Ethernet uuinterface to host controller
