Conclusion

• Demonstration Of A New Cobra Probe Card With

Increased Bandwidth:

– 20X Bandwidth Improvement Over Conventional Cobra

Probe Card (Micro Coax).

– 3-4X Bandwidth Improvement Over Conventional Cobra

Probe Card (Twisted Pair And Direct Cable To Card

Connection).

• High Speed Line Bandwidth Limitation Gated By

Cobra Head.

Paths To Higher Frequencies:

– Engineering 50 Ohm Cobra Head.

– Using TFI Contactor.

• New Probe Card Can Be Constructed In 4-6 Weeks.
