This course enables trainees to understand the IPC-A-600 external appearance quality requirements of circuit board products, and to have a standard and judgment criteria when judging appearance.
This document is a teaching material for the IPC‑A‑600E standard, which defines the visual acceptability criteria for printed circuit boards. It presents the purpose of the course, an outline of topics, and references to related IPC specifications.
The material details PCB classification (Class 1‑3), acceptance criteria (Target Condition, Acceptable, Nonconforming), and specific test methods such as cleanliness and solderability testing, providing tables and examples for each quality attribute. This manual is written in Chinese.
The standard was created by IPC, the Institute for Interconnecting and Packaging Electronic Circuits.
IPC‑A‑600E defines three classes of printed circuit boards: Class 1, Class 2, and Class 3.
