# Introduction

This dataset focuses on identifying and annotating various defects and features in printed circuit boards (PCB). The goal is to accurately detect and label different types of anomalies and components that can affect the functionality of PCBs. The dataset contains the following classes:

- **Copper**: Irregularities in the copper layer.
- **Mousebite**: Small, jagged gaps along the edges.
- **Open**: Breaks in the circuit path.
- **Pin-hole**: Tiny perforations on the surface.
- **Short**: Unintended connections between traces.
- **Spur**: Unwanted protrusions from traces.

# Object Classes

## Copper

### Description
Copper anomalies are irregular shapes, typically darker than the surrounding area, indicative of issues in the copper layer.

### Instructions
Annotate the full extent of the irregular dark shapes within the circuit paths. Do not label shadows or reflections that resemble copper anomalies.

## Mousebite

### Description
Mousebites appear as small, jagged gaps along the otherwise smooth edge of the circuit paths.

### Instructions
Identify and annotate jagged disruptions along the edges. These should be distinct from regular edge smoothness. Do not mark regular wear or smooth curves as mousebites.

## Short

### Description
Shots are clear separations in the circuit path, appearing as breaks.

### Instructions
Annotate the entire gap visible in the circuit path. Ensure that the separation is clearly an open and not a thin trace. Do not label small gaps that are not short open faults.

## Pin-hole

### Description
Pin-holes are tiny, circular or oval perforations on the surface.

### Instructions
Find and mark the small circular voids. Make sure they are not merely surface marks but actual holes.

## Open

### Description
Opens are unintended connections between circuit paths, typically creating a bridge.

### Instructions
Annotate the connection line that bridges two separate traces. Make sure that the connection is unintentional and not part of the design.

## Spur

### Description
Spurs are unwanted protrusions from the main circuit trace.

### Instructions
Identify and mark the protruding lines or extensions that deviate from the main trace. These should not follow the usual trace paths and must be seen as unintended additions.
