Abstract:
A probe tip arrangement to minimize probe loading and cross-talk in a dense pad array, comprising:a pad located in a dense pad array;a first probe tip resistor having a first end coupled to the pad, wherein the first probe tip resistor is adjacent to the pad;an access transmission line coupled to a second end of the first probe tip resistor and extending outside of the dense pad array;a second probe tip resistor located outside the dense pad array and coupled to the access transmission lineat least one aggressor conductor located in close proximity to the access transmission line wherein a redefined capacitance is created between the aggressor conductor and the access transmission line; andwherein the first probe tip resistor comprises a first resistance and the second probe tip resistor comprises a second resistance the first resistance and second resistance being predetermined to minimize an amount of cross-talk between the aggressor conductor and the access transmission line, and to minimize an amount of conductor loading on the pad.
