ICAMS Test Bed (Isotropic Conductive Adhesive Measurement System)

Bumps

Task

Long-time examination of the conductibility of isotropic adhesive bindings. Additional stress of the test samples by variable electrical and climatic conditions, such as current, temperature and humidity. (Photo: Fraunhofer IZM)

Requirements

  • Assembly in climatic chamber for cycle tests
  • Wiring temperature stability over 100°C
  • Measurement data aquisition with up to 400 channels
  • Measurement accuracy better than one milliohm
  • Free configurable measurement
  • Automatic syntax check of the given measurement configuration
  • Automatic hardware check of the realized wiring
  • Graphical visualization of the measurement data (during measurement or off-line)
  • Automatic searching and short-circuiting of defective test samples
  • Simple adaption of the software for future requirements
  • Off-line data analysis with commercial software
LabVIEW Application

Solution

Software development and programming in LabVIEW (National Instruments). Data acquisition with DMM 2010 and Switch Mainframe 7002 (Keithley Instruments) via GPIB und RS232. Use of ambitious graphic visualizing possibilities (ZoomIn, ZoomOut). Evaluated measurement data are saved as spreadsheet ASCII file.
