Abstract: A method for measuring a distance between connectors of different line cards is described. A first measurement component configured on a first line card sends a measurement signal to a second connector configured on a second line card using a first connector configured on a first line card, and determines a distance between the first connector and the second connector based on the measurement signal. The second connector receives the measurement signal and sends a response result of the measurement signal back to the first measurement component, to enable the first measurement component to determine the distance between the second connector and the first connector. The distance between the first connector and the second connector being determined based on the measurement signal enhances flexibility, universality, and accuracy.

Abstract: This application relates to a circuit board assembly. The circuit board assembly includes: a first circuit board. The first circuit board is connected to a connector; and a second circuit board. A first connecting portion is disposed on the second circuit board. The first connecting portion is electrically connected to the connector. The second circuit board includes a top surface and a side surface. The top surface intersects and is perpendicular to the side surface. The first connecting portion is disposed on the top surface, and extends towards the side surface. In this disclosure, the top surface intersects and is perpendicular to the side surface, to improve stability of connection between the connector and the first connecting portion, and improve working stability of the second circuit board, so as to improve working performance of the circuit board assembly and improve user experience.
