PROBE TESTING - Test accessories

Microworld offers you a complete range of accessories and sub-assemblies supplied with the probe station, integrated and put into operation during installation.
They can also be retrofitted in most cases.

These boxes are used to isolate the component under test of external disturbances such as light or magnetic radiations during probing analysis
• Size, configuration and connections are customized per application
• The biggest model contains the entire test station while the basic model is more like suitcase-type 
• Dark box or Faraday cage depending on the application and filtering needed​

Specific cameras adapted to microscopes with a trinocular head
• Designed for an efficient visual support and able to produce detailed photogtaphies
• Capture and measurement software supplied in standard with the cameras
• High resolution up to 5 Megapixels
• Connection to computer or external video

 

They are proposed when the test requirements demand a specific configuration for non-standard parameters
• Applications for low current, high power
• Specific models for temperatures, hot or hot/cold with cooling down circuit
• Custom manufacture for components with a specific shape, or non standard dimensions...

Our range of temperature controllers associated with a specific chuck will allow you to measure under needes all your devices according to your test requirements at high temperatures
• Models heating up only, ambient to 300°C and more
• Tri-temp versions for hot/cold testing
• Ramp option allows varying the temperature for a set of measurements
• External GPIB control, triax low current option..

Set of control softwares aimed to programming and driving test instrumentation equipment of various models runs on a pc with a user-graphic-friendly interface 
• Main software : PACE
• Applications : Component characterization, process monitoring, failure analysis, incoming inspection control, Go/no go...
• Signatone's probe station control
• Custom development for devices as Keithely, Keysight, Rhode & Schwarz...

From the basic joystick model to the high-end submicronic version, our positioners are used on all types of probers to access conductive pads or lines down to the micron
• Economical models include three control knobs on each side and rear
• Highest models have in-line knobs preserving maximum space on the platen
• A high frequency RF range is available
• Hold down to the platen is magnetic or by vacuum or bolt-down (RF versions)

 

Our range of microscopes suits all applications of visualization at either low or high magnification, with adapted ligthting by Led or optical fiber. The microscopes are usually mounted on probe stations but they can be supplied with separate post and table for inspection, incoming control...
• Binocular or trinocular (for camera mounting) head with continuous zoom
• "High power" microscope with multi-objectives turret
• Mono-objective models with electronic magnification
• Digital Cameras, accessories, objectives

The probe holders are standard for passive, coaxial / triaxial isolated probes, they are used with all positioners of our range except RF models
• Standard model U serie for probe tip of diameter up to 0.6 mm
• Coaxial model with 50 ohm cable and BNC connection
• ​Triaxial version offering a very low noise level <2A when used with a dark box and triaxial chuck
• High Voltage version leakage current <1nA, factory tested up to 1500V

An efficient filter of vibrations induced by the environment allow placing probe tips in contact with very small structures. Regardless of the test station designed for fine probing or not, the use of an antivibration support is necessary in most cases.
• The tables are available in two categories : Passives (with marble platen) or suspended on air cushion
• The size of the platen is adapted to the equipment to support
• Choice of options : Tabletop for monitor, rolling wheels... 
• Applications : For all equipment where environmental vibrations need need to be low to operate properly
