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. 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. The FLS system offers double-sided probing and up to 24 probe modules on the component and solder side of the Unit Under Test (UUT) to facilitate efficient single pass testing.

Accuracy

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 variable 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 encumber traditional in-circuit testers and other flying 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 20 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
• LaserScan profiles board warpage
• Electronic measurement system relies on precision circuits and components for reliable and repeatable measurements
• Integrator™ system control software with sophisticated motion control and measurement algorithms ensures robust and repeatable operation.

Throughput

Test times on a Flying Probe system depends mainly on the number of test steps and speed of probe movement. Shorts Test consume a large part of overall test time. The 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. Key Features of AccuFast Drive System™

• Faster than open loop systems (1.5x)
• High acceleration (4x)
• Enhanced probing accuracy
• Three times better dynamic response +/- 1 degree rotation
• Automatic orthogonality between X and Y axis
• Sensorless homing (no adjustments)
• DSP based motor controller
• Built-in linear and parabolic interpolation (more efficient shuttle movements)

Patented Multi-Probe System

The FLS system has a modular architecture that is expandable to 22 probes. The probe modules have easily interchangeable probe tips. A range of probe tip styles are available off the shelf. In addition to providing excellent test coverage on densely populated circuit boards, this flexibility makes the FLS980x an ideal solution for testing backplanes where direct contact with connector pin tips is required.
