摘要: Unitized probe tip assemblies of reduced size for a micro-browser use surface mount components in an isolation/coupling network that may include parallel RC combination series with damping resistor. These are soldered directly to one another without the substrate. A pointed contact is end components, and at other those center conductor coaxial transmission line leading replication amplifier. portion enclosed within supporting conductive shield also outer cable, which be semi-rigid micro coax (which might memory metal, such as Nitinol) transitions into flexible cable after leaving slot sleeve carries stationary rotating rods metal) unitized attached. In alternate embodiment shaft resistive diamond having sharp where it has low bulk resistance functions resistance, toward much higher isolation shunted by coupling capacitance formed pattern printed on outside region resistance.
