# Introduction
This dataset focuses on annotating electronic components on printed circuit boards (PCBs). The goal is to identify and label specific components using bounding boxes for component recognition and classification. The classes in the dataset include various components such as capacitors, integrated circuits (ICs), LEDs, and resistors, along with their respective footprints.

# Object Classes

## Capacitor
### Description
A rectangular component with metallic ends, often mounted flat on the PCB.

### Instructions
Annotate the entire visible body of the capacitor, ensuring the bounding box encloses both metallic ends and the main body. Ignore any solder connections not integral to the component itself.

## Capacitor Footprint
### Description
Patterned area on the PCB indicating where a capacitor should be placed, usually marked with pads or outlines.

### Instructions
Enclose the marked pads or outlines on the PCB dedicated for capacitor placement. Do not include adjacent traces unless they are part of the footprint.

## IC Bottom
### Description
The bottom view of an Integrated Circuit, showing pins and a dark, flat body.

### Instructions
Draw bounding boxes around the visible chip body and pins. Ensure all pins are included within the annotation, focusing solely on the component itself.

## IC Footprint
### Description
The outlined area on the PCB that interfaces with IC pins, typically a rectangular set of pads.

### Instructions
Outline the entire footprint marked on the PCB for an IC, ensuring that all pads designed for pin connections are within the bounding box.

## IC Top
### Description
The top view of an Integrated Circuit, characterized by a smooth, often branded surface with pins around its perimeter.

### Instructions
Enclose the entire top surface of the IC along with its visible pins. Ensure any labels or marks on the top surface are centered in the annotation.

## LED Bottom
### Description
The underside of a Light Emitting Diode, generally a small square or rectangular component with metallic contacts.

### Instructions
Draw bounding boxes including the entire body of the LED and its metallic contacts. Do not include any mounting or surrounding board elements.

## LED Footprint
### Description
The designated area on the PCB for an LED, typically featuring small pads for connections.

### Instructions
Outline the footprint area on the PCB, capturing all pads and marks meant for LED placement. Adjacent circuit elements are to be ignored unless part of the footprint.

## LED Top
### Description
The top view of an LED, often small with a slightly raised dome or flattened surface.

### Instructions
Capture the entire body of the LED in the bounding box, including any visible lens or dome shape. Ensure no surrounding components are included.

## Resistor Bottom
### Description
A generally rectangular component with metallic ends, often seen mounted horizontally on the board.

### Instructions
Include the complete body of the resistor and its metallic ends in the annotation. Avoid including excess solder or trace areas unless directly attached to the resistor body.

## Resistor Footprint
### Description
The marked area on a PCB for resistor placement, featuring two pads or outlined areas.

### Instructions
Enclose the marked zone for resistor placement without extending the box beyond the designated pads or outlines.

## Resistor Top
### Description
The top view of a resistor, usually showing a smoother body with possible label markings or color bands.

### Instructions
Annotate the whole top-facing surface of the resistor, ensuring any visible markings are within the bounding area. Exclude unnecessary board elements not part of the resistor.
