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.

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).
