Our customers' issues • Apertures are getting smaller • Paste does not release as well • Contaminates the bottom of the stencil • Increases defects / reduces yield  Insufficient solder  Bridging  Solder balls on surface of PCB  Flux residue • Requires more frequent cleaning • Reduced efficiency (wasted time) • Increased use of consumables (cost)  USC fabric (use "cheap" fabric to reduce cost)  Lint creates more defects  Cleaning chemistries (use IPA to reduce cost)  IPA breaks down flux and can create more defects
