A state that may not be perfect but will still result in a reliable solder joint. Defect Conditions:
IPC-7527 processes match the three foundational classes of the electronics manufacturing industry: IPC-7527 - Requirements for Solder Paste Printing ipc7527 pdf fixed
Based on available information:
Implementing a "fixed" process means locking in your Solder Paste Inspection (SPI) limits according to standard tolerances. SPI systems use 3D optical measurements to evaluate three primary metrics against the nominal stencil aperture volume. IPC-7527 Recommended Control Limits Common "Fixed" Production Limits (Depending on paste type) Area Volume (Tightened for fine-pitch) Registration (Offset) of pad width for ultra-fine pitch 4.
