IPC-A-610 PCB Assembly Standards: Class 1 VS Class 2 VS Class 3
IPC-A-610F is a pictorial guide that establishes visual acceptance criteria for printed circuit board assemblies (PCBAs). It does not dictate how to build a board—that is the role of IPC J-STD-001 —but rather defines what the finished product should look like to be considered high-quality. Key topics covered in the standard include: ipc-a-610f pdf
The is a critical technical document for the electronics manufacturing industry, serving as the global standard for the "Acceptability of Electronic Assemblies." Originally released in July 2014, Revision F brought significant updates to visual inspection criteria, specifically addressing newer technologies and clearer language for inspectors.

Criteria for board cleanliness, marking, and conformal coatings. Criteria for board cleanliness
Visual examples for various termination styles and component alignment.
The standard divides electronic products into three classes, allowing manufacturers to tailor quality requirements to the product's intended end-use:
Detailed requirements for both lead-free and tin-lead solder joints.
