Microsystem manufacturing, assembly and packaging technology in Display-Card™ applications

The SWECARD Display-Card™ has the same dimensions as a standard credit card, yet also features a display and buttons that make it possible to view stored information. The applications are endless: airline tickets, bankcards, loyalty cards, health cards and security/ID cards. Because of the size of the card, the microsystems manufacturing, assembly and packaging technology is extremely important to ensure a successful mass production. During the development of the cards and two small-scale productions, we encountered problems such as short circuit, misalignment, leakage, etc. However, these proved to be solvable with adjustments in our technology. This paper will address all the issues in this area and shed light on new ideas in the future R&D work.
