Multi-power hybrid FPC-to-board connector reduces PCB mounting space by 46%

Hirose has extended its hybrid FPC-to-board connector family to include a multi-power version that supports high power capacity in a compact, space-saving design. The BK11 Series multi-power hybrid FPC-to-board connector is equipped with two main power contacts supporting 4A per pin, four sub-power contacts supporting 2.5A per pin, and ten signal contacts. By decreasing the number of signal contacts, the series helps save up to 46% of mounting space compared to conventional hybrid connectors.

With a 0.35mm pitch, 1.9mm width, 5.33 mm length, and 0.6mm stacking height, the series allows OEMs to decrease the size of portable devices without sacrificing performance.

The series provides selectable power contact usage, providing design flexibility for designers of smartphones, wireless earbuds, smart watches and other wearables. The BK11 power contacts can be configured as:

• 4A x 2 positions plus 2.5A x 4 positions
• 8A x 2 positions

The FPC-to-board connector features a fully armoured design that covers both ends of the housing with metal for improved robustness and a substantial reduction in the risk of housing damage from misalignment when mating. A wide self-alignment range of ±0.32mm (pitch direction) and ±0.23mm (width direction) simplifies mating operation. Designed for pick and place mounting, the series provides production time and cost savings.

“The multi-power hybrid BK11 Series offers enhanced features and capabilities that enable end-devices to be smaller, lighter, and more reliable,” said Pete Lais, AVP of Product Management for Hirose Electric Americas. “Adapting to various power circuit designs, the BK11 Series simplifies layout and allows greater flexibility for component placement, such as USB ports, supporting a wide range of product architectures and form factors.”

The compact BK11 Series also features a moulded plug and receptacle design that helps stop solder wicking, further enhancing manufacturing reliability.
