Anwendung
  • Bow and twist measurement of PCBs and components during soldering
Eigenschaften
  • Possible objects: PCB, BGA; QFP, DCB; (additional objects on request)
  • Max. object size 200 mm *150 mm
  • Simultaneously measurement of smaller objects possible
  • Max. temperature 260°C
  • Heating modes: infrared (max. temperatur ramp up 2 K/s) and simulated convection (0,25 K/s)
  • Measurement resolution in z-direction 1 µm
  • Max. repeatability 2,5 µm (depending on object)
