MFB 2500

Dual Interface Card Production System

Mühlbauer’s Flexible Bump technology offers a well proven system that guarantees an absolutely secure connection between chip and antenna for dual interface cards. This is achieved with the unique and patented Flexible Bump process, ensuring electrical connection even when the card is intensively used.
The latest generation MFB 2500 offeers even more stateof-the-art ingenuity and the flexibility of integration into existing production lines without additional upgrades. This solution combines the both unique and patented  technologies antenna touch milling as well as the Flexible Bump process in one system. The MFB 2500 offers the lowest costs per card especially for high production volumes with a throughput of up to 2,500 cards / hour. Thanks to a vision system as well as the possibility of re-working this system guarantees 100% good cards and a maximized yield.
