Target specifications with feasibility
1.Available Fine Pitch and CCC
2. Probe Life Maximum T/D = 4,000k
This T/D number was obtained in actual achievement in device customer's plant in Japan using canti-lever probe of tip diameter 20μ and made of Iridium. Pad material was Aluminum.
3. CRes < 0.5 Ω
Result of VPT Principle Confirmation Test, using Φ29μ Rhodium pin.
4. BCF : Balanced Contact Force
VPT is like symmetrical cobra. So, BCF was estimated by data of cobra.
