What are you currently using? (Type 3, Type 4, water-soluble, no-clean) Are you using automated 3D SPI or visual inspection? ipc7527 pdf free download free
Modern SMT lines utilize 3D SPI systems directly after the screen printer. Aligning your SPI programming tolerances with the acceptable limits defined in IPC-7527 ensures that insufficient volume, bridging, or shifted print deposits are immediately flagged and automatically adjusted by the printer's feedback loop.
