Mechanical Micromechanical Measurement
Electronic Microelectronic Measurement 1
 Application 2 : Gold contacts on PCB board
Electronic Microelectronic Measurement 3

    Aims :

  • Non contact measurement of gold contacts on a PCB board,
  • Control of the co-planarity of the contact summits,
  • The contacts and the substrate have very different reflectivities.
