Abstract
A loading apparatus for loading a printed circuit board (PCB) stack including one or more PCB layers and transferring the PCB stack to an inspection probe includes a movable support unit, a guide unit and a cover. The guide unit is provided on the support unit and defines a depression portion in which the PCB stack is mounted. The cover is configured to cover the depression portion of the guide unit when closed, where the cover has multiple protrusions extending from a lower surface, which press the PCB stack into the depression portion when the cover is closed.
Claims18
A loading apparatus for loading a printed circuit board (PCB) stack comprising one or more PCB layers and transferring the PCB stack to an inspection probe, the loading apparatus comprising:
- a movable support unit;
- a guide unit provided on the support unit and having a depression portion for mounting the PCB stack therein;
- and
- a cover for covering the depression portion of the guide unit when closed, the cover having a plurality of protrusions extending from a lower surface, wherein the plurality of protrusions press the PCB stack into the depression portion when the cover is closed.
A printed circuit board (PCB) inspection system, comprising:
- an inspection probe for measuring thicknesses of one or more PBC layers in of a PCB stack;
- and
- a loading apparatus configured to load the PCB stack and to transfer the PCB stack to the inspection probe, the loading apparatus comprising:
- a movable support unit;
- a guide unit on the support unit and defining a depression portion for mounting the PCB stack therein;
- and
- a cover for covering the depression portion of the guide unit when closed, the cover having a plurality of protrusions extending from a lower surface, wherein the plurality of protrusions press the PCB stack into the depression portion when the cover is closed.
A method of measuring a thickness of a printed circuit board (PCB) stack comprising one or more PCB layers using an inspection probe and a loading apparatus comprising a movable support unit and a guide unit provided on the support unit, the method comprising:
- loading the PCB stack into a depression portion of the guide unit;
- closing a cover over the depression portion, causing a plurality of protrusions extending from a lower surface of the cover to press the PCB stack into the depression portion of the guide unit, securing the PCB stack in an initial position;
- moving the loading apparatus to the inspection probe;
- and
- determining a thickness of the PC B stack using the inspection probe.
