OLED INTEGRATION
1.6. Contacting via Flex-PCB
The application of Flex-PCBs (fl exible printed circuit boards)
allows the connection of an OLED device with wires by stan-
dard selective solder process (heat tip). Devices with more
than two contact ledges can be connected by only two wires
without any branches. Furthermore, depending on the de-
sign, Flex-PCBs are bendable due to their low thickness in
the range of 300 µm.
As an example, fi gure 5 shows a Flex-PCB (left) attached to
an ORBEOS ® CMW-031 (right). The Flex-PCB has four con-
tacts to the OLED and 8 areas for external wiring. Figure 5.
c) illustrates the Flex-PCB of an ORBEOS ® RMW-046. Several
different wiring modes are possible using the fl ex connector as
shown in fi gure 6.
Fig. 5. Free-standing Flex-PCB with four fl aps (a) attached to an ORBEOS ® CMW-031 (b). The eight golden soldering pads of the Flex-PCB are visible. Each one provides a positive and
negative pole as well as a through contact “0”. ORBEOS ® RMW-046 (c) can be equipped with a fl ex connector with two soldering pads on both sides (front side and back side).
Fig. 6. Various wiring options. These can be realized with the help of the Flex-PCB
shown in fi gure 5.
