Abstract
In some examples, a system receives a first image of a circuit board produced by a first production stage, and compares the first image to a second image of the circuit board acquired at a second production stage for the circuit board. The system indicates an anomaly with the circuit board based on the comparing.
Claims20
A method comprising:
- receiving, by a system comprising a hardware processor, a first image of a circuit board produced by a first production stage;
- comparing, by the system, the first image to a second image of the circuit board acquired at a second production stage for the circuit board;
- and
- indicating, by the system, an anomaly with the circuit board based on the comparing.
1 more element
A non-transitory machine-readable storage medium comprising instructions that upon execution cause a system to:
- receive a first image of a circuit board produced by a first production stage;
- receive a second image of the circuit board acquired at a second production stage for the circuit board, the second image acquired prior to processing of the circuit board by the second production stage and after processing of the circuit board by the first production stage;
- compare the first image to the second image;
- and
- indicate an anomaly with the circuit board based on a mismatch of the first image and the second image identified by the comparing.
2 more elements
An imaging apparatus comprising:
- a first imaging sensor to capture an image of a first surface of a circuit board in an imaging zone;
- a second imaging sensor to capture an image of a second surface of the circuit board in the imaging zone, wherein the second surface is on an opposite side of the circuit board from the first surface, and
- wherein the first imaging sensor and the second imaging sensor are to concurrently acquire the images of the first surface and the second surface;
- and
- a conveyor system to provide relative motion between the circuit board and the first imaging sensor and the second imaging sensor.
