Wearable devices have developed very rapidly in recent years. However, everyone's attention is focused on the product's creativity, shape, or processor, platform, etc., but it ignores one of the seemingly inconspicuous but important devices, that is, the connector.
Most wearable devices will be accompanied by or "second" mobile devices, typically connected to smartphones using short-range, low-power wireless methods such as Bluetooth low energy or Wi-Fi Direct. Wearable devices such as smart watches and smart glasses are similar, optimized for communication data, as well as display of notifications and alerts. Both types of devices are complex and compact, and their interconnect requirements are the same, requiring signal and power integrity in a very space-constrained environment. Board layout limitations include the use of double-sided PCBs, which will require the use of FFC/FPC “flex” (flex) connectors for micro-coax interconnects where shielding is required. The rapid growth of smartphones and tablets is a good example of how innovative manufacturers can create new markets, and this will have a profound and far-reaching impact on the way people work, play, get news and entertainment, and communicate. We expect portable and wearable device electronics to continue to grow. At the same time, the appeal of wearable devices is slowly increasing, and these products may not be popular, but many new products are already in the prototype construction phase.
