SMK Develops Industry’s Smallest FPC to Board Connector
for Wearable Devices

   SMK Corporation has developed the “FB-1E” FPC to board connector for battery connection with new structures and expanded “FB series”.
   Connectors for battery connections in the wearable device market need to be smaller and thinner than smartphone. This product has achieved a significantly smaller size with a 0.5mm stacking height (the lowest in the industry*), 1.5mm width, and 3.2mm length, compared to the connectors used in smartphones, which commonly have a 0.6-0.7mm stacking height, 2.0-2.5mm width, and 4.3-6.0mm length. The mounting area is also one of the smallest in the industry, with a 52% reduction compared to the company’s conventional product.
   It has three signal pins besides power pins for an increased number of signals as batteries become more multifunctional.
