Printed Circuit Board Panel Measuring Table

Printed Circuit Board Panel Measuring Table


The panel measuring table offers a quick determination of the etching distribution after differential etching processes or the plating build-up of copper surfaces. The measurements are carried out fully automatically by a resistive sensor after entering the input parameters.

Subsequently, the measuring points are evaluated by a PC and converted into a 3D diagram, statistics tool included.

  • Precise and repeatable: fully automated measurement avoids manual handling and operation error

  • Fast: 100 measuring points in 3.5 min

  • Flexible: accommodates variable panel formats

  • Quality control of etching and plating processes

  • Process drifts are easy to spot and to correct

  • Reduction of yield loss by early detection
