FPOR20110 is automatic material test system for Dk/Df measurement. The frequency range could be support from 20 GHz to 120 Ghz. It could provide accurate and stable material parameters to materials development engineers and circuit design engineers. RF substrate material parameters and the roughness between the substrate and the copper foil are critical for circuit design engineers to use analog software to design circuits. It is the first testing system that can measure Dk/Df of materials as well as surface roughness. FPRO20110 can support DUT thickness ranging from 10um to 1mm.

Millimeter wave material measurement systems can provide valuable information for the development and characterization of new material in various industries. There systems user electromagnetic waves in the millimeter wavelength range to probe the physical properties of materials such as their dielectric constant, loss tangent, conductivity and thickness.

By measuring these properties the millimeter wave material measurement system can help manufactures optimize the performance and reliability of their products, such a printed circuit boards (PCBs), flexible boards, ceramic substrates and packaging materials.

The transmission loss included dielectric loss and conductor loss. Conducting loss dominated by the interface of substrate and metal. The hemispherical Fabry Perot Open Resonator (FPOR) with a reflective structure of signal is good tools for measurement dielectric properties and metal loss.

The Model 110H Picoprobe which in- corporates our patented coaxial design tech- niques, has inherent low loss and low dis- persion characteristics. Through its unique design, the Model 110H Picoprobe achieves an insertion loss of less than 1.5 dB and a return loss of greater than 15 dB over its frequency range. With individually spring loaded, Beryl- lium-Copper tips, the Model 110H pro- vide reliable contacts, even when probing non-planar structures. This reliable low resistance contact is one of the keys to providing highly repeatable measurements at W band frequencies. Like all of our Picoprobes, the Model 110H allow direct viewing of the probe tips for accurate positioning. Any pitch (tip spacing) from 50 to 1250 microns may be specified. The probe can be configured with Ground-Signal-Ground (G,S,G), Ground-Signal (G,S), or Sig- nal-Ground (S,G) tip footprints. We rec- ommend smaller pitches with a G,S,G footprint for best performance. The Model 110H utilizes a female 1.0mm connector..

The GGB Industries Model 67A probe sets new standards in microwave probing performance. Using low loss coaxial techniques, the Model 67A achieves an insertion loss of less than 1.1 db and a return loss of greater than 14 db through 67 GHz With its individually spring loaded, Be- ryllium-Copper tips, the Model 67A pro- vides reliable contacts, even when probing non-planar structures. This reliable low resistance contact is one of the keys to providing highly repeatable measurements. The Model 67A also provides direct view- ing of the probe tips for accurate position- ing. The Model 67A can be mounted in various adaptors for use with standard microwave probe stations. Custom mounts are avail- able. Any pitch (tip spacing) from 50 to 1250 microns may be specified. The probe can be configured with Ground-Signal-Ground (G,S,G), Ground-Signal (G,S), or Signal- Ground (S,G) tip footprints. We recom- mend smaller pitches with a G,S,G foot- print for best performance. Connection to the Model 67A is through a female 1.85 mm V connector. (2.4 mm compatible)

Flexible Tips for Flexible Probing

Each Model 67A has patented, independently spring loaded tips which make contact to the probing surface. Because the tips are flexible they minimize circuit damage, increase probe life, and most importantly, provide a reliable individually spring loaded contact for each point. With a small amount of overdrive, the point scrubs the surface to make a reliable contact free of dust, dirt, and oxide contamination. The ability to view the exact contact area eases probe positioning and allows for the precise positioning necessary for good LRM calibrations. The flexible tips even allow probing of non-planar surfaces such as ceramic substrates and laser diode structures.

Coaxial Transmission Improves Performance

The Model 67A uses a precision miniature 50 ohm coaxial cable from the probe tips to the connector interface. The coaxial design provides lower loss and less radiation than coplanar designs. The miniature coaxial cable is fabricated from flexible Beryllium- Copper which greatly improves the probeís durability.
