Half a million touch sensors delivered and no field returns

In 2015, Canatu was presented with a challenge: create a touch sensor for a light application that tolerates zero colour shift. Nothing on the market could deliver a robust touch solution with the right colour tone and production was imminent. On the lookout for an ideal solution, the customer had identified Carbon Nanotubes (CNT) as the ideal material for the application and selected Canatu because of their industry-leading performance.

The timeline to production? 3 months. As an agile company Canatu addressed the challenge with speed, delivering the first samples within 3 weeks. Its in-house touch sensor prototyping facility was an invaluable resource in creating a finished touch sensor from the initial concept in record time. Those very first samples met the customer’s functional and aesthetic requirements.

Convinced by the capabilities, the company rewarded Canatu with its first mass production order for a transparent 3D touch controller. The customer’s confidence was well placed; Canatu has delivered half a million sensors with zero field returns ever since.

Steep learning curve

For a small company, winning a mass production order represented as major leap forward from small scale sampling.

“Back then, our total headcount was only 15. When we got the first order, we had to implement robust manufacturing processes and quality controls in a very short time.  This meant everybody pitching in on all aspects from manufacturing to testing and quality control. We pushed beyond our normal comfort zones and were literally learning by doing but fulfilling that first large order made it all worthwhile, “said Liam Osuilleabhain, Product Manager and Canatu employee since 2013.

Scaling up with partners

Once mass production was in place and stable, Canatu made a strategic decision to focus on its core technology development. Production was transferred in a phased, controlled manner to one of its qualified partners. This freed up Canatu’s resources to support its growing customer and application base.

Establishing outsourced production was the next step in evolving Canatu’s mass production capability; CNBTM film and fast prototyping at its headquarters combined with high-quality, established partners for volume shipments. Canatu’s unique end-to-end supply chain management from film production to sensor delivery allowed it to tightly control the quality and performance of each delivered sensor.

“Thanks to our well-controlled process, the field return rate remains at zero, and we keep getting positive customer feedback month after month. This is concrete proof that our technology solves real customer needs and meets the stringent requirements of the automotive industry,” says Markku Lamberg, Vice President, Customer Projects and Supply Chain.

Mass manufacturing at the new Vantaa factory

Canatu has further enhanced its manufacturing capability. Today, CNBTM films are manufactured in a brand-new factory that was inaugurated in November 2019. This facility houses a fully automated, roll-to-roll film manufacturing line which delivers higher volumes to supply the growing need for touch sensors and heaters in next-generation autonomous vehicles.
The new facility is already built to support further manufacturing lines.

Canatu has an additional film and sensor prototyping line at its factory. This enables fast turn-around samples and small-scale production to support our customers from initial concept right through to mass production.

“With enhanced manufacturing capabilities, we are able to scale up very quickly and serve several product lines in the future, “Lamberg concludes.
