The new way to solve existing challenges


The pace of semiconductor device miniaturization is posing unprecedented challenges to the established testing industry. As nodes get smaller and components sizes shrink, the increased interconnect density demands innovative solutions. Accessing smaller pads with finer pitches requires lower and well-defined probe forces.


Introducing Exaddon micro3D probes


Exaddon micro3D probes are generated from a unique micro3D printing technology which unlocks high tip positioning accuracy and unprecedented small pitches. The extreme precision results from a “print at place” approach; this eliminates any inaccuracies resulting from replacing probes or human interactions, as can happen with other technologies. With Exaddon, <20 µm pitch is now accessible! 


Exaddon’s modular probe card design allows for fast and convenient probe head exchange, giving the shortest average time to repair. It is easily adapted to other test pad layouts - all with the same probe card.

Spotlight: MicroLED Parallel Testing

Exaddon’s process delivers probes of customizable design, 3D printed directly on microPCBs. This multi-layer microPCB acts as the interposer, probe head, and fan-out. It is compatible with current probe stations. 


With 128 probes, our microL64 gives microLED testers a 64x increase in test efficiency. A wafer that would otherwise require 2 months for 100% testing can now be inspected in less than a day.


The layout of Exaddon’s microL64 probe head is customizable, and with a pitch of less than 20 μm, we are breaking the current industry limit and setting the start point for a new era in enabling scaling down the size of microLED testing.


The exceptional planarity (±2 µm) allows for low overdrive,  decreasing the testing time.


MicroLED testing with Exaddon's 3D printed probes has received excellent industry reception in Taiwan, Japan and the USA.


Beyond microLEDs, any applications which need fine-pitch probing stand to benefit from this approach, including parametric test, microbump contacting, RF applications, and more.
