Components

Hassle free integration

A key feature of our Cri/oFlex® technology is the integration of microwave filtering components on the flex. This reduces the number of breakouts on the chain, limiting the number of components (mainly connector), simplifying installation and removing points of failure.

In-House Parameter Control

We control conductor thickness, channel width, and channel pitch to match electrical and mechanical requirements with consistent repeatability.

8-Channel Stripline Standard

Each standard flex contains eight channels, with pitch spacing selectable from 0.1 mm to 1 mm for optimized routing and density.

Precision-Controlled Stripline Dimensions for Cri/oFlex®

Conducting strips are deposited and patterned as circuits on a shared dielectric layer. Because Cri/oFlex® is produced fully in-house, we can define and control key thin-film parameters such as conductor thickness, individual channel width, and the pitch between channels. A standard Cri/oFlex® stripline includes 8 channels per flex with adjustable pitch, while conductor geometry can be tuned from nanometer-scale films up to tens of microns to meet functional requirements. Flexible section length is available across a broad range, with extended lengths achievable using Tabbi/™ interconnects.

Length Scales with Tabbi/™

Flexible sections can be built from 5 to 100 cm, with extended lengths beyond one meter enabled using Tabbi/™ interconnect.

Compact Form Factor with Tunable Geometry

Cri/oFlex® combines high channel density with a compact footprint, while allowing geometric tuning where needed. Pitch, conductor width, thickness, and total length can be configured to balance routing constraints, transmission targets, and system integration requirements.nducting flex solutions specifically for cryogenics, combining durability, flexibility, and performance in one standardized platform.

Attenuator

The transmission of Cri/oFlex® can be as low as 1.5 dB/m at 6 GHz for NbTi. For our Silver (Ag) platform a typical 6 dB/m at 6 GHz at low temperatures is normal. In the field these losses are denoted as insertion losses.

On the graph the Silver transmission is plotted for different temperatures.

Below the transmission are the S11 reflections graphs shown. These are known in the field as reflection losses, as they appear as reflections for the system. The Cri/oFlex® is overall well below 15 dB for each reflection. For more information contact our engineering team.

Low-pass Filter

Our low-pass filters are based on a distributed element LC design and have a customizable (options: 1, 8 GHz) cut-off frequency with flat roll-off in the pass band and 40 to 60 dB suppression in the stop band. In the figure, we plot the typical spread of an 8-channel Cri/oFlex® 3x with this type of filter. Also, it shows the close matching between the measurements and our simulation. Low pass filters are currently available on Ag-based Cri/oFlex®. By integrating these filters, noise and undesired frequencies can be surpressed at the quantum device.

System integration

Integration

There is a wide variety of cooling solutions for quantum computing and low temperature experiments, ranging from lab size dilution refrigerators to small 4K table-top systems. As an i/o provider, it is our task to connect quantum devices and cold experiments to the control electronics regardless of the cooling implementation. To that end we have developed standardized solutions that fit (or can be made to fit) all fridges.

Whether you are purchasing a new system or want to refurbish your current system, Cri/oFlex® provides a solution.
