Production and Supply Chain
What is Carbice’s total capacity?

We have been shipping products to customers for over 2 years with repeat orders. Our capacity today will meet your needs. Our new Atlanta facility is ramping now to a capacity of 20 football fields’ of material per year.

MINIMIZE
Can Carbice help me mitigate my supply chain risk?

Yes. Our innovative process flow and abundantly available and sustainable raw material stack can significantly reduce supply chain risk in this challenging environment.  Talk to your Carbice contact to discuss flexible inventory solutions and lead time management options for high volume products.

MINIMIZE
Is the Carbice factory certified for Aerospace and Defense product manufacturing?

Yes, Carbice has both ISO9001:2015 and AS9100D certifications. Our Quality Management System is certified to meet the highest standards in the industry and will exceed your expectations.

MINIMIZE
Does Carbice currently deliver to large customers in Aerospace and Defense?

Yes, we supply the Primes, established Aerospace and Defense companies, as well as several innovative new entrants. We do not disclose our customer relationships due to confidentiality agreements.

MINIMIZE
Is Carbice technology ITAR restricted?

No, there are no restrictions on Carbice technology or products.

How do I choose the best Carbice Pad for my application?

Carbice® Ice Pad™ is where most customers start, because it meets the needs of the widest range of applications. Space Pad™ is geared towards space and low-outgassing applications, and Contact Pad™ is designed to excel with make-and-break contacts or sliding contacts.

Once you have chosen the right type of Carbice Pad, our product selector allows you to consider all the real factors that affect your thermal interface performance. Carbice Lab lets you reach the right solution with unprecedented speed. See product pages for more details.

MINIMIZE
What is the CTE of Ice Pad, Space Pad, Contact Pad?

Vertically aligned Carbice Nanotubes act as stress reliever at the interface: they attach, slide, and move like springs at the nanoscale. As a result, the Carbice Pad interface will not delaminate due to stress – no matter how large the CTE mismatch in the interface.

MINIMIZE
Is there a minimum or maximum torque or force that I have to apply for Carbice Pads?

We hear you. Grease and traditional pads only work in a small torque or force window. That is not the case with Carbice Pads. With our material, you are free to choose the torque or force that works best for your needs. The tensile strength of Carbice Nanotubes is 10 times that of steel. In our product, each individual Carbice Nanotube is covalently anchored to the aluminum core. They will bend to meet the curvature and roughness of your interface exactly, but they will never break.

MINIMIZE
Do Carbice Pads produce foreign object debris/damage (FOD)?

No. Greases and PCMs migrate out of fastened interfaces. Graphite and silicone pads can release particles from their edges due to tear and compression set. In contrast, when a Carbice Pad is fastened in an interface, it stays in place and generates zero FOD.

MINIMIZE
Can Carbice Pads be reworked and reused?

Yes. Carbice Pads are the most robust thermal interface materials (TIMs) in the world.

MINIMIZE
Are Carbice Nanotubes electrically conductive?

Carbice Pads can be used for electrical grounding with our metal coatings. Carbice Pads can be used in applications where you would typically use a dielectric grease or pad, because you are concerned about migration or FODs causing electrical shorts. See the question about FOD above.

MINIMIZE
Have Space Pad been used on an ESA or NASA program?

Yes, the first Space Pad cooled NASA program was successfully launched in 2018. Since then Carbice Space Pads have been cooling spacecraft big and small. Contact us and we will share more.

Carbice SIM Software
What is Carbice SIM?

Typically, every part of an electronic system can be simulated before it is built. However, thermal interface performance could only be assessed conducting in-assembly tests… until now. Carbice SIM is the only simulation tool that can model the actual conditions of your interface in operation. It is so accurate that it is able to match experimentally collected data within ±10%, even in thermal vacuum (TVAC) test settings.

MINIMIZE
How do you run the simulation? What inputs do you need?

Carbice SIM is a 1st principle modeling tool. It takes inputs from real application interface conditions: interface geometry, materials, atmosphere, and loads from the joint. We solve mechanical and structural problems – e.g. your potted inserts won’t pull out. We output real-world thermal performance – which saves a lot of time and money testing for the right material and assembly.

MINIMIZE
Does Carbice SIM also model other thermal interface material and get similar accuracy?

Carbice SIM provides highly accurate modeling projections for Carbice products only. This is because grease and other TIMs either migrate, exhibit compression set or, in general, don’t perform consistently over time and cycling. When the material moves around unpredictably, exhibits high levels of inelasticity, or degrades, it introduces non-linear effects that pose intractable simulation and forecasting problems. Modeling any of these TIMs will never match the results of actual experiments. Carbice Pads are different; their thermal, mechanical, chemical, electrical properties are so consistent and quantifiable that we’ve been able to achieve ±10% accuracy in our projections.

MINIMIZE
If I want to use your Carbice SIM software to model my interface, what parameters do I need to provide to you for accurate results?

We will need to know the heat density, whether there are hotspots. We typically need a drawing of your interface, your interface material information, and fastening loads. If you do not have a drawing to share, we can still work with you to get the information necessary for your application.

MINIMIZE
Can you model hotspots or non-uniform heating?

Yes. We can model unique heating conditions and recommend a suitable solution.

Carbice Lab
What is the Carbice Lab?

Most semiconductor companies do not manufacture their own chip. Much like fabs have developed broad expertise and affordability serving different customers, the cost of thermal innovation demands a similar model. Carbice Lab leads the way with this new model to lower the cost of thermal design for the industry. We can do it all for you: design, simulate, test, produce, and ship.

MINIMIZE
If I want to out-source thermal design, do you have in-house TVAC test capability alongside Carbice SIM to verify my design?

Yes. We have the equipment in-house and include it as part of our testing procedure.

How To
How do I apply, rework and clean up the interface with Carbice Pad?

We have you covered and it is simple. It is all documented in our installation guide which we provide for each product we ship.

MINIMIZE
How do I dispose of Carbice Pads at the end of the application life?

Carbice Pads will outlive your application. When your device is recycled our products are easy to remove: simply peel them off. They can be recycled at the same facility that recycles aluminum cans.
