Accurate micro-SMD probing

SPEA Automatic Flying Probe Tester

Miniaturization won’t stop and SPEA’s Flying Probe systems are ready for the future.

  • Top-performance linear optical encoders on XYZ axis
  • Micro-SMD (008004) pad accurate contacting
  • Reliable test of flexible/thin printed circuits, Sticky Boards
  • Positioning measurement stability over long time
  • Ultra-Fast Soft-Touch technology: no touch damage, no stress on PCB and Micro-SMD

Best Measurement Accuracy

SPEA Automatic Flying Probe Tester
  • Highest measurement performance & accuracy (0.1pF)
  • Signal integrity
  • No measurement degradation or interference
  • Immediate signal acquisition (within hundreds of microseconds)

Fast Probe Speed

  • Top-performance linear motors on XYZ axis
  • Highest speed of movement
  • Maintenance-free: no tear and wear can affect accuracy
  • Mechanical stability over time

Multi-Mode Probing


4020 S2 can combine the 4 high-speed top flying heads with additional tools to contact the bottom side of the board, increasing throughput and test capabilities.

Each flying probe can be used for in-circuit test, power-on test, sink/source analog, digital D/S, flashing via on-board programming, boundary scan, prescaler.

While using the 4 top probes to perform flying probe test from the top side, a bottom lifted platform can be used for bed-of-nails fixtures, multiple high-current power supplies, digital I/O, high-speed signals, fixed probes, planarity supports.
