Etching Aluminium Antenna & FLIP

It's the latest way of producing card in these years base on the technology of FLIP inlay with thinner thickness and coherence of frequency. It could produce contactless card without any trace on card surface.

Advantage
1, High quality, better coherence antenna frequency
2, the best flatness surface and invisible the FLIP chip position.
3, Thickness card inlay could up to 0.3mm to 0.45 for HF card
4, higher speed production
Weakness
1, Higher cost of cards
2, High cost for customize card antenna design.
3, Weakness in laminated fastness of card, if no experience.
4, Expensive equipments of manufactory need.
