Requirements for Probing Materials
Because the end uses of chips are often in harsh conditions, the conditions under which wafers are probed must also be harsh. Heat transfer fluids must provide efficient heat transfer so that set-point temperatures are reliably maintained for the probing system. Probe cards must be made of materials with very low thermal expansion and good dielectric properties.
