Automated In-Line Test Handler for Electronic Products and PCBs

The FlexCell NT is a high efficient test handler with directly integrated test system to be integrated into fully automated electronic assembly processes. The integrated test system offers cableless contacting from the test probe to the instrument, ensuring zero-failure operation over long production period.
 

The FlexCell NT represents the latest generation of automated test handlers for electronic test automation with many unique attributes. Implemented in compact space the FlexCell NT allows the fully automated test of electronic assemblies and PCBs at the highest possible quality. Outstanding feature is the support of a so called wireless mode, where the signal transmission from the test probe up to the measurement device is implemented entirely without cables. This allows precise measurements under absolut stable conditions and a high test accuracy.

Integrated into the test handler is a steppless contacting mechanics based on servo motors for testing diverse products without the need for costy conversions of the handler. Combinations of functional test and in-circuit test are possible due to its steppless lifting mechanics. Vertical lifts are automatically locked against unintended lowering.

Sufficient space is available for integrating barcode readers and DUT marking systems or pneumatic systems incl. actuators. Potentially required additional electronic cicuits can be implemented on the motherboard.

All measurement signals are guided entirely cableless via spring probes, rigid needles and pogo pins in a combination of DUT-specific fixture kit and the test system‘s motherboard to the instruments inside of the ABex-based test system.

Integrated ABex Test System

One of the outstanding features of the FlexCell NT is the direct integration of the test system. This integrated ABex-based system is equipped with all necessary instruments and switching boards depending on the specific test requirements for functional test and/or in-circuit test, AOI test, boundary scan test as well as in-system programming.

Integral component of the ABex design is a signal backplane and a powerful terminal module concept, allowing cableless signal interconnections across all instruments and system modules. Depending on the test configuration a multiple stage contacting lift can be implemented if necessary.

The test system is vertically integrated into the handler and posesses a cableless DUT interface to the DUT-specific fixture kit of the handler.

Fixture Kits

According to the test requirements we outfit the test handler optionally with a cableless or a cable-based fixture kit. The cableless variant offers big advantages, notably stable electrical conditions and an increased reliability of operation. At DUT sizes extending dimensions of 300 mm x 422 mm we are equipping the handler with cable-based fixture kits.

Optionally, we are offering the Konrad microalignment technology to be used on our fixture kits for reliable and precise contacting of extremely small structures.
