Introduction of the "FB3BA5 Series" Board to Board Connector for Smart Devices.

  • Product news

We have developed an ultra-compact Board to Board connector that pursues miniaturization with a mating height of 0.5mm, signal contact pitch of 0.30mm, width of 1.55mm, and a length of pitch total + 2.48mm. By leveraging our technological capabilities in connector development, we enhance our customers' design flexibility and contribute to the advancement of smart devices. Additionally, this connector reduces volume by approximately 40% compared to conventional products with the same number of pins, contributing to a reduction in environmental impact by decreasing material usage.
