Micro Prober Electronic Circuit Board Testing Machine｜FA Products

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

System that improves test reliability

RFID system enables management of fixture information enhances maintainability and prevents installation errors
Statistical analysis tool useful for process improvement checks the statistical information of test result on the spot
Data code management function enables traceability management of each pieces
