Pin arrangement and electronic assembly

摘要

A pin arrangement adapted to a FPC connector is provided. The pin arrangement includes a pin lane. The pin lane includes a pair of ground pins, a pair of differential pins and at least one not-connected (NC) pin. The differential pins are located between the pair of ground pins. The at least one NC pin is located between the pair of differential pins or between one of the pair of ground pins and one of the pair of differential pins adjacent thereto. By adding the at least one NC pin between the pair of differential pins and/or between the differential pin and the ground pin adjacent thereto, a distance between each of the pair of the differential pins and/or between the differential pin and the ground pin is increased, and thus a differential characteristic impedance of the pair of differential pins is raised to reduce the impact of impedance mismatch.

1. A pin arrangement, adapted to a flexible printed circuit connector, the pin arrangement comprising:
a pin lane, comprising:
a pair of ground pins;a pair of differential pins, located between the pair of ground pins;at least one middle not-connected pin, located between the pair of differential pins; anda pair of side not-connected pins, wherein each of the pair of the side not-connected pins is located between one of the pair of ground pins and one of the pair of differential pins adjacent thereto and is not located between the pair of differential pins.
