Micro Prober Electronic Circuit Board Testing Machine

Industry-standard testing machines for electronic circuit boards achieving high productivity and contact accuracy simultaneously.
The pass rate and throughput greatly affect the productivity in the electrical testing process of circuit substrates.
While improving both of these has proven difficult using the existing fixture method or flying method, Yamaha's Flying Fixture™ method has solved this.

Features of Micro Prober

Simultaneous achievement of productivity and probing precision

  • Uses the Flying Fixture™ method where a small fixture moves quickly
  • Enables contact with an object with high positioning accuracy without moving a circuit board
  • High contact accuracy of +/- 5 μm reduces the pseudo OPEN and misalignment probing

High repetability and reproducibility

  • Uses the Step and Repeat method where camera alignment and contact are repeated
  • Minimizes effects of circuit board expansion and contraction, improving the contact accuracy
  • Upper and lower independent positioning testing fixtures enable stable inspection even if there is an interlayer displacement between the two sides

Thin or large substrates corrected to be flat

  • Stable work holding by clamping 4-corners with tension
  • Our original clamping mechanism holds a circuit board at 4-corners to apply the optimum tension in XY direction
  • Even thin, large-sized and excessively-warped circuit boards which are difficult to handle are set flat

System which is independent of operators' skill

  • One-touch fixture replacement enables to reduce costs for work, such as start-up and setup change significantly
  • Automatic probing position adjusting function allows anyone to adjust and maintain optimum inspection conditions
  • Well designed GUI allows the device to deliver its performance sufficiently
