WL-210 RF / Microwave Probe Station
The Signatone analytical probe station is recognized as the performance / value leader in the microprobing market. The WaveLink Series extends this expertise into the RF & MW sector, historically subjugated by more expensive alternatives.
While RF & MW probing have been classified by some as a difficult, mysterious application, this is no longer the case. Any modern probe station precise enough to contact a sub-micron line is certainly stable enough to hit a 100m pad with a 50m RF probe. What's more, in the past decade, we have seen improved network analyzers having more stability, accuracy, and ease of use. Signatone believes your probe station should be equal to the application requirements.
Building on the proven CheckMate architecture, and in consultations with our installed base of RF technologists, Signatone has incorporated many features into the WaveLink Series unique to the world of VNA's and coplanar probes.
WL-170 RF / Microwave Probe Station
The Signatone WL-170 is very similar to the WL-210 with the exception that it uses the WL-1160 style X-Y wafer stage. The WL-170 maintains the larger platen and the greater stability that WL-210 users love, then incorporates the simple X-Y stage from the WL-1160 to save a few bucks and has quicker X-Y knob transition. The WL-170 is available in 150mm.
WL-210E Probe Station
Many applications benefit from an isolated probing environment, such as full-range thermal, 1/f, noise-figure, load-pull, and low-leakage CV/IV probing, yet don't require a fully-automated platform.
Offering mechanical isolation and precise sub-µ positioning, the WL-210E Probe Station is the ideal choice, while still retaining the option to upgrade to semi-automatic in the future.
WL-1160 Probe Station
Microwave probing on wafer level devices requires several components. Signatone working together with Picoprobe offers a complete turnkey package including
G-S-G Probes by Picoprobe
Picoprobe offers two probe heads; the model 40 for frequencies of DC to 40GHz and the model 67 for frequencies of DC to 67GHz. Each head has a "K" connector for attaching the signal cable. Spacing between tips may be specified between 50m and 450m. The Picoprobe head uses a flextip technology on the ground lines
Microwave Probe Head & Manipulator S-M90
Signatone's model S-M90 features 25mm of X-Y translation and 12mm of Z. A pivot adjustment assures planer contact of the G-S-G probe. The micropositioner body has a rigid construction to assure no back lash when moving the probe head even with the rigid and semi-rigid signal cable attached to the probe head. The manipulator is available with magnetic or rigid mounting bases. Also, orientations of east, west, north and south permit up to 4 probes or wedges to be used simultaneously. The micropositioner will accept Picoprobe or Cascade microwave probe heads.
Manual Microwave Probe Station
Signatone's model S1160MW probe station is available in 3 chuck sizes; 100mm, 150mm and 200mm. Each of the probe stations feature a four point platen lift for stable uniform lifting of probes with 1m repeatability. The X-Y stage features a coaxial knob control for X & Y control and resolution of 5m. An additional fine stage permits precise positioning to a micron. The microscope stage has 50mm of X-Y translation. It will accept either stereozoom or high-powered microscopes.
A calibration substrate is available for the probe heads used from Picoprobe. The substrate includes shorts, opens, thrus, and 100Ω resistance load pads matched for the probe head spacing ordered.
Semiautomatic Microwave Probe Station
Signatone's smart semi automatics have a variety of options and features. It is available in 150mm or 200mm formats. The semiautomatic has the same sturdy features found in the manual probe station
In addition, it has the ability to step and repeat as well as run automatically. Included as the probe station controller is an AT computer running Windows 3.1 based software.
Signatone Solutions software allows setting up of complex probing applications and easy control of all motions. The 'Point and Shoot' feature allows the user to point to the target probe site on the computer screen and the chuck will move to that position. The system also features 2 point alignment for quick aligning, wafer mapping ofgood or bad die, soft Z control and many other features
