Final Assembly Flying Probe Testing Services

Scorpion1We offer assembly testing services which are specially focused on reducing engineering debug efforts on small and medium production runs.
Maintaining high product quality while keeping production costs low, together with aggressive schedules and time to market pressures, force manufacturers to choose lean yet effective test and quality assurance strategies for their production processes.

Flying probe testers require no test fixtures, have few restrictions on board access, and can test boards with virtually unlimited number of nets, allowing developers to turn test programs around in a short time.
scorprobeThe new generation of flying probes come from the application of new and innovative ideas to provide increased test speed, improved access, and greater fault coverage. The move away from the restrictions of 4-probe, fixed angle, single sided test systems has become a fundamental necessity in achieving highest test coverage and maximum through-put in a competitive and constantly changing manufacturing environment.

Key Features

  • Proven double-sided probing
  • Multi-probe system (up-to 24)
  • flsBoardtestQuick and easy test program generation from CAD or Gerber data
  • Precision analog test
  • Power-off Open Pin detection on ICs, connectors, and other devices
  • Board power-on test
  • Boundary Scan (JTAG) test
  • Mixed signal function test
  • On-board device programming
  • Advance fault coverage report generator


We can test boards whose layout, size, and technology used to defy testing on traditional in-circuit testers and 'moving' probers.



fls900_3The Flying Scorpion tester relies on two software modules for processing board CAD data (XMatic) and generating an executable program on the Flying Scorpion Tester (Integrator). Short programming cycles and high system flexibility make the Flying Scorpion an ideal choice for production ramp-up, prototyping, and low to medium volume production testing.

Highest Fault Coverage

The high speed and precision analog measurement unit provides 4-wire measurements capability for all 24 flying probes (top and bottom sides). All probes can perform in-circuit tests as drivers, sensors, or guards on discrete and integrated analog/digital components.

Open Pin Detection

We use Acculogic's Open-Pin-Detect (OPD) toolset for power-off “Vectorless” detection of open pins on digital and mixed-signal devices is an important test capability. OPD provides fast programming and comprehensive manufacturing process fault coverage.

ChipScan™ and CScan™ patented vectorless tests extend fault coverage to ICs, including BGAs, and ICs with heat sinks, as well as connectors and polarized capacitors.



Boundary Scan test (JTAG) is a test methodology based on IEEE 1149.1 standard. Compliant Semiconductors, when installed on a circuit board, allow the interconnecting nets and digital clusters such as memory devices to be tested using a simple external physical set-up. Boundary Scan (JTAG) also offers a comprehensive board-level protocol for programming flash and other programmable devices.

Integration of boundary scan test into the flying probe environment translates into important advantages;

  • Dramatic increase in test coverage by combined use of flying probe and boundary scan resources
  • More efficient shorts test using flying probes and higher throughput
  • Reusable Boundary Scan test patterns
