UFO Probe® card – new test card for PIC wafer testing
Photonic Integrated Circuits (PICs) are the chips of the future. Integrated photonics use light instead of electricity for data and signal processing.
Speed up the world
UFO Probe® Technology keeps you one step ahead
A step ahead with Jenoptik
New Jenoptik UFO Probe® Vertical
The consistent further development of the patented technology expands the possibilities of optical coupling and, with the new UFO Probe® Vertical version, enables parallel functional tests of optical as well as electrical components on chips using vertical needle technology from established test card manufacturers. This allows the user to couple up to 32 optical channels in parallel as standard - or more if required - without the need for active alignment.
Opto-electronics tests with high throughputs:
- Covers the entire wavelength range from 1260 to 1625 nanometres used in the telecommunications and data communications sector
- Provides polarization preservation for individual or all optical channels
- Contacting of up to 6000 bond pads/ of bondpads with dimensions down to 35 microns (depending on the needle type, even more)
- Also possible solder bumps and copper pillars
- Smallest addressable pitch of the electrical contacts in the range of 40 to 80 micro
- Lower and more uniform contact resistance in the range of 0.2 to 1.0 ohms (depending on the probe type)

All benefits of the Probe Card Technology on one view
The PIC ecosystem can be expanded thanks to an efficient test method for high-throughput serial production; and the test time is reduced thanks to parallel qualification of multiple chips.
The only commercial test solution for high-volume production that can run on standard test equipment.
Scrap is identified at an early stage of production for improved yield: All testing of all PICs can be carried out on a wafer.
Plug and Play
It is designed to operate in standard IC testers and automated testers. Low outlay and commissioning costs.
Fault parts are identified early on for increased yield and optimized production flow.
The pitch and number of optical I/O channels can be configured to suit you.
Enabling optical data communication
