Test Access

FLS-Flying-Probe-double-sided-test-probing-angleShrinking 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. The FLS980 Production Test Platform 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, 01005. The FLS system 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.

Accuracy

FLS-Flying-Probe-tester-accuracyDue 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. The FLS980 system architecture ensures repeatability. Closed Loop Drives for shuttles and probe modules ensure precise and repeatable positioning of the probes.
  • Riding on a 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

Acculogic-FLS980-Flying-Probe-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, FLS980’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.

Probe Module Types

The FLS980 automated test 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 5 types of probe modules available for the system:

Design Recreation Tool – Genesii

(also known as Reverse Engineering)
Servicing legacy products could be problematic for repair depots if there is no automated test or test system in place for this purpose. Tests programs can quickly identify what is causing boards to fail. If up to date board design information is available, then test programs can be easily generated. But what if design files are not available for test development? The consequence is a time consuming and expensive troubleshooting process. But with Acculogic’s Genesii Design Recreation software, you can recreate the required file (netlist) for test program generation.

Automated Netlist Generation

The process starts with a bare PCB and an assembled printed circuit assembly. Then, through image processing techniques, Gerber files are generated. Using Acculogic’s XMatic software, the Gerber files and parts information are processed to create an input file for the FLS980 Flying Probe platform. This input data is utilized by Genesii to intelligently map board connectivity as information is captured through probing pads on the board. After all PCB connections have been identified, the netlist file is complete and ready to use for test program development.

Laser Based Measurement – LaserScan

Acculogic-FLS980-Flying-Probe-Laser-Measurement-System
LaserScan is installed on a shuttle and allows certain critical functions to be performed with added precision in the FLS test systems.
  • It measures the distance between the probe and the UUT, thereby allowing precise targeting of the UUT test points when the flying probes travel at an angle
  • It is used to determine the coplanarity of the UUT and compensate for warps and bumps on the board
  • It is used to measure height of components, create package and board profiles, and append height

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.
