Introduction #

Released 2019-02-22 Β·Runwei Ding, Linhui Dai, Guangpeng Liet al.

Augmented PCB Defect is a dataset designed for object detection, encompassing 10,668 images with 21,664 labeled objects across six distinct classes, including mouse_bite, missing_hole, spurious_copper, and others such as spur, open_circuit, and short. Meticulously curated with a focus on Tiny Defect Detection (TDD), this dataset plays a pivotal role in advancing quality control measures in the production of printed circuit boards (PCBs), a fundamental and crucial aspect of manufacturing processes in the electronics industry.

This dataset is the result of comprehensive experimentation conducted on the original PCB Defect Dataset (available on DatasetNinja). The initial dataset comprises 693 PCB defective images, each annotated with corresponding files. The average pixel size of each image in this dataset is 2,777x2,138. The PCB defects are categorized into 6 classes, including missing hole, mouse bite, open circuit, short, spur, and spurious copper, with each image potentially containing multiple defects. Recognizing the limitations of the small dataset, data augmentation techniques were applied before training, and subsequently, the images were cropped into 600x600 sub-images. This process resulted in the creation of a training set and a testing set, comprising 9,920 and 2,508 images, respectively, contributing to a more robust and diversified dataset for the development and evaluation of object detection models in the context of PCB defect detection.

PCB defects can be divided into two categories: functional defects and cosmetic defects. Functional defects can seriously affect the performance of PCB, which may lead to the abnormal usage of PCBs. These defects are the most serious defects. Cosmetic defects mainly affect the appearance of PCB, but also damage its performance in the long run due to abnormal heat dissipation and distribution of current. Among the two categories, there are six kinds of defects which frequently appear in the actual industrial scene. Here, authors mainly study these six known and common defects which contain missing hole, mouse bite, open circuit, short, spur, and spurious copper.

Summary #

Augmented PCB Defect is a dataset for an object detection task. It is used in the manufacturing industry, and in the damage detection domain.

The dataset consists of 10668 images with 21664 labeled objects belonging to 6 different classes including mouse_bite, missing_hole, spurious_copper, and other: spur, open_circuit, and short.

Images in the Augmented PCB Defect dataset have bounding box annotations. All images are labeled (i.e. with annotations). There are 3 splits in the dataset: train (5120 images), val (3414 images), and test (2134 images). The dataset was released in 2019 by the Peking University and Shenzhen Skyworth-RGB Electronic, China.

Co-occurrence matrix #

Co-occurrence matrix is an extremely valuable tool that shows you the images for every pair of classes: how many images have objects of both classes at the same time. If you click any cell, you will see those images. We added the tooltip with an explanation for every cell for your convenience, just hover the mouse over a cell to preview the description.

Images #

Explore every single image in the dataset with respect to the number of annotations of each class it has. Click a row to preview selected image. Sort by any column to find anomalies and edge cases. Use horizontal scroll if the table has many columns for a large number of classes in the dataset.

Object distribution #

Interactive heatmap chart for every class with object distribution shows how many images are in the dataset with a certain number of objects of a specific class. Users can click cell and see the list of all corresponding images.

Class sizes #

The table below gives various size properties of objects for every class. Click a row to see the image with annotations of the selected class. Sort columns to find classes with the smallest or largest objects or understand the size differences between classes.
