IPC-7527 provides specific thresholds for common printing errors. For example, is generally considered acceptable if the paste is centered within approximately 20% of the pad width , though Class 3 often requires tighter precision. Other critical defects covered include:

If your SMT line prints any board thinner than 0.8 mm, or any board with components below 0.4 mm pitch, . The cost is small compared to the rework and scrap it will help you avoid. ipc-7527 pdf

The IPC-7527 standard provides comprehensive requirements for solder paste printing, covering stencil design, material selection, and process optimization to ensure assembly quality. It defines inspection criteria for common defects, such as misalignment and insufficient paste, while outlining necessary handling, storage, and environmental controls for the paste.
