Improved robustness with fine line print
One of our long-term customers – a global leader within major appliances – approached us with an interest in optimizing one of their products.
They needed an improved robustness of the capacitive touch sensor used for one of their control panels – We investigated and implemented a technology change.
The task for Mekoprint was to:
- Qualify roll-to-roll fine line printing of conductive silver traces down to 50 um,
- contribute to re-design and lifetime qualification of the capacitive touch sensors
- and subsequently to deliver the technology in mass production.
Besides qualification of new production technology, the open dialogue and trust, also created a strong platform for collaborating and achieving higher quality and delivery performance for both parties.
Anders Menholt, Key Account Manager, Mekoprint
“We greatly appreciate the holistic collaboration, which in many ways represents the partnership we seek with all our customers - a collaboration where we lift each other to a higher level. We have developed in the same direction within quality and delivery. We have proven the ability to create products in joint development and introduce new technologies together. And we have implemented process improvements in a dynamic and high-volume production.”
100% TEST OF ALL SENSORS
In the production of the ultra-thin fine line traces, the human eye falls short.
Hence, investments were made in:
State-of-the-art automated optical inspection systems
Implemented in several key processes throughout production
Roll-to-roll flying probe electrical test technology
Making it possible to test the functionality of all sensors before shipment
This project improved the solution for our customer. But the learning and investments made will benefit all other customers – with production, test and vision systems supporting low ppm-levels.
