Abstract

The invention discloses a method and a device for transferring and testing an interlayer board card. The interlayer board card switching method comprises the steps of welding a board card connector connected to an interlayer board card to one side of a switching circuit board; Welding a PCIE slot connected to the consistency test fixture to the other side of the switching circuit board; Arrangingwiring on the switching circuit board to enable the board card connector to be connected with the PCIE slot; And testing the consistency of the interlayer board cards by using a consistency testing jig. According to the technical scheme provided by the invention, switching and testing can be performed for different interlayer board cards or different types of interlayer board cards, so that the consistency of the interlayer board cards can be evaluated, and the design reliability of the interlayer board cards can be improved according to test feedback.

Description

technical field [0001] The present invention relates to the field of software, and more specifically, relates to a method and device for switching and testing intermediate boards. Background technique [0002] The OCP (Open Computer Project) intermediate card standard is a mezzanine card standard formulated by OCP. This standard is used to expand PCIe network cards, serial port cards, etc. in high-density servers, and can be directly connected to the motherboard for use. OCP requires less installation space than standard PCIe cards and retains the flexibility of PCIe standard cards. [0003] The PCIe connectors of the OCP middle layer cards commonly used in high-end servers can be divided into three types: OCPA, OCPB, and OCPC. The gold finger of the OCP connector is different from the standard PCIe slot, and the pin definitions corresponding to the OCP connector on the system motherboard are also different from the standard PCIE pins, but there is no complete PCIe-OCP form...
