Flying Scorpion FLS980Dxi – Flying Probe Tester





Our flagship products, the FLS900™ Series of Flying Probe testers, help ensure that tomorrow’s technologies don’t outpace today’s test capabilities. These products are highly advanced, scalable solutions made to solve a wide range of test challenges. Acculogic’s systems are made to accommodate a variety of applications and customers. At the core of our high-performance test systems lay the technologies needed to counteract next-generation test challenges.


Tight quality control measures together with time to market pressures are compelling manufacturing companies to choose effective yet lean test and quality assurance strategies in 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. They also allow developers to complete test programs in a short time. For these reasons and more, flying probe testers have become indispensable tools in today’s electronic manufacturing.



Application of new and innovative design features to increase test speed, board access, reliability, and repeatability, have opened up new possibilities for deployment of Acculogic’s FLS900 series testers. As the first patented flying prober with double sided testing and 22 interchangeable probe modules, the FLS980Dxi is leading the way in defining new leaner and more efficient deployment models for production environments.


Test Access

Shrinking component sizes and denser chip scale packaging technologies are posing new challenges to test engineers. Test pads, traditionally installed on PCBs, are being eliminated from many designs thus reducing physical access. Flying Probers are required to operate with unprecedented precision in order to meet the new challenges. FLS980 uses highly repeatable closed loop linear motor drives and joystick-like variable angle probe modules to maximize physical access and guarantee repeatable probing of fine pitch devices and small components like 0201, 01005s. FLS980 offers double-sided probing and up to 22 probe modules on the component and solder side of the Unit Under Test (UUT) to facilitate efficient single pass testing.




Due to its modular and scalable architecture, the FLS980 guarantees superior probing precision and repeatability. Precise Closed Loop planar linear motors (shuttles) with “AccuFast™ Drive System” (1 micron minimum step size, +/-10 micron positioning repeatability) independently move probe modules and cameras. The probe modules utilize equal-length identical probes to contact target points on the UUT. Each probe module is able to set the probing angle from 0º to 6º from vertical in any direction. The combination of shuttles’ positioning and joy-stick like probe motion ensures unmatched accessibility to points on the UUT. You can now test boards whose layout, size, and technology defy testing on traditional in-circuit and other moving probe testers. FLS980Dxi system architecture ensures repeatability Closed Loop Drives for shuttles and probe modules ensure precise and repeatable positioning of the probes.

  • Riding on 12 micron air gap, shuttles travel free of friction and with no mechanical contact on the stator plane and therefore operate free of wear.
  • High resolution fiducial detection cameras, precise lighting, and advanced image processing software ensure precise and repeatable detection of fiducial marks on the UUT as well as correct compensation for any offsets.
  • The electronic measurement system relies on precision circuits and components for reliable and repeatable measurements.
  • Integrator Pro™ system control software with sophisticated motion control and measurement algorithms ensures robust and repeatable operation.


Probing Angle

Warping of printed circuit boards is a common issue that should be taken into account in SMT board assembly, inspection and test processes. During Flying Probe test, board warp changes the physical position of target points by an offset. When probing angle is 0 degrees from vertical, board warp will cause no probing errors, however, as the probing angle increases, the probing error also increases. A 0201 chip on a board with 0.5 mm warp using 15 degree probing angle cannot be probed dependably. Decreasing probing angle to 3 or 4 degrees reduces warp related uncertainty, and leads to reliable probing.


Offering optimum probing, FLS900’s Advance probe modules rely on a patented design to probe target boards Omni-directionally on the horizontal, and -6 to +6 degrees on the vertical planes. As probing angle increases the probe slippage factor increases. Probe slippage can lift pads and vias and leave unacceptable marks on the target.



PROBING ANGLE of Acculogic's Flying Probe Tester












Probe Module Types


The FLS900 systems can be configured with up-to 22 Probe Modules on top and bottom side to ensure maximum access and optimum test time. There are two types of probe modules available for the system:

  • Basic Probe Module BMP 700 with fixed angle (+6°)
  • Advanced Probe Module APM 800 with programmable angle ( 0 to +6°)

System can be configured with mix of the variable and fixed angle probe modules. The flying probe drive systems has a positioning accuracy of 1 micron minimum step size, +/-10 microns positioning repeatability, which provides reliable probing of target sizes as small as 100 microns ( 4 mils) in production environment. To probe even smaller targets in special applications Acculogic provides higher precision probe modules and cameras as future upgrades.


Probe Module Specifications:

  • 3D Programmable Angle 00 – 60 (+6° for fixed angle)

Test time on Flying Probe depends mainly on the number of test steps and speed of probe movement. Shorts Test consume a large part of overall test time. FLS980’s flexible measurement system provides a host of test strategies including Boundary Scan (JTAG) and NetScan™ to significantly reduce test time without impacting test coverage or repeatability. In addition AccuFast™ Closed Loop Drive system boosts speed and acceleration by 4 times over open loop systems.

Vectorless Test

PinScan™ Patented Open Pin Detection suitePinScan is a complimentary suite of analog and digital test techniques for detecting Opens on ICs, including BGAs, as well as connectors and polarized capacitors.

  • CScan™ is a patented technique used in vectorless testing of ICs and connector pins. CScan is used to test open pins as well as the polarity of electrolytic capacitors. CScan functionality detects open pins on devices located on the top and/or bottom side of the board.
  • ChipScan™ is a patented 3-pin technique for vectorless open testing on digital IC pins. It exploits the parasitic diodes/transistors in each digital IC, and tests each pin for open faults. Power up is not required in order to use ChipScan. This method is particularly useful where bus structures are used. ChipScan detects wire bonding defects, open pins and cold joints. ChipScan functionality is available on all probes covering top and bottom side of the unit under test.
  • ScanProbe™ is a digital technique that uses flying probes to detect opens on digital IC pins of devices that are IEEE-1149.1(JTAG) compliant. ScanProbing is fast and repeatable, uses the digital and boundary scan capability of the FLS900 for fault detection.
  • Active CScan™ combines the coverage of CScan with the power of Boundary Scan. It draws the best from each technology to increase the test coverage and reduce the test time therefore enhances overall capability of Flying Scorpion
  • ThermoScan™ uses the mechanical capability of its flying probe to automatically move an infrared temperature sensor over the PCB to measure the powered PCB temperature pattern. This new test method bridges the gaps between conventional test technologies.




ThermoScan™ can be used at every stage of the production process. It can be used for design verification and helps to optimize the thermal distribution. This will increase the mean time between failures (MTBF) for products in the field, decreasing warranty cost. It also can be used to efficiently repair PCBs returned from the field. ThermoScan™ quickly provides useful troubleshooting information, dramatically reducing repair time.


Acculogic’s ThermoScan™ can measure and analyze the thermal behaviour of single-sided and double-sided PCBs. The systems’ temperature range is from -18 to 220°C with a measurement accuracy of 3 percent.


The PCB Operation involves the flow of electrical current, which produces heat when passing through a circuit having resistance. The temperature pattern on an operating IC, or assembly can be a good, repeatable indication of its operational status.

Boundary Scan


  • Fully integrated hardware and software
  • IEEE 1149.1 and IEEE 1149.6 supported
  • Support for multiple scan chains up-to 8
  • Scan and non-scan testing
  • Automatic test optimization
  • Automated test generation and intelligent diagnostics

Boundary scan (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 on the FLS900. Furthermore, Boundary Scan offers a comprehensive board-level protocol for programming flash and other programmable devices. Integration of boundary scan with flying probe systems is no longer an option but a requirement since the combined strategy improves test coverage and test time. Boundary scan is an integral part of the FLS900; digital test patterns generated by Acculogic’s powerful ScanNavigator software are delivered to the UUT through Probe Modules or board carrier system. FLS900 goes beyond interconnect testing by providing full digital test capability when and where needed. This technological break-through is made possible by merging Acculogic’s two powerful software suites, the “Integrator Pro” and the “ScanNavigator”.


“Boundary Scan, not an afterthought but an Integral part of the System.”


FLS900’s advanced boundary scan extends the testing to assemblies that contain a mix of Scan and non-Scan logic by providing Shorts Test between boundary scan nets and non-boundary scan nets where the non-scan nets have flying probe access.



  • 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

Device Programming

FlashScan™– In-Circuit Device Programming Programmable devices such as PLDs, Flash, PROMs are frequently used on most modern circuit board assemblies. In-production-programming (configuration) of these devices provides the flexibility for on-the-fly content changes as opposed to using pre-programmed parts. Device Programming on the FLS980 improves production efficiency by removing an extra step in the production process.


FlashScan™ is a multi-vendor integrated hardware and software suite that provides the FLS980 with capability to program and verify a wide range of devices.


SPC Software

Statistical Process Control Software Integrator Pro’s SPC software is a powerful statistical process control (SPC) tool that analyzes and identifies variations in test results due to variations in process environment. Using a series of measurements made repeatedly on a single board or on batches of production boards, developers are able to identify measurements that are least stable. They can then examine these measurements for root causes of instability and alleviate the causes. SPC software allows developers to analyze test variance due to noise, component variation, drift, and system variance. Test limits can be updated automatically under user control to obtain solid production-ready tests.
