In brief
The stencil controls aperture geometry and transferable ink volume. Select it against the smallest feature, ink particles, target deposit and print area together.
A finer mesh may improve feature definition, but it changes opening size and ink deposit
A finer mesh may improve feature definition, but it changes opening size and ink deposit. High-solids or particle-filled conductive pastes also need sufficient passage through the mesh. Supplier technical data is more useful than a universal mesh-count rule.
Emulsion thickness affects edge geometry and deposit; low mesh tension may slow release and disturb registration
Emulsion thickness affects edge geometry and deposit; low mesh tension may slow release and disturb registration. SAATI documents industrial meshes and emulsions with different resistance to UV, solvent and water-based ink systems.
Compare edge ragging, opens, pinholes, film uniformity and screen release on the same artwork
Compare edge ragging, opens, pinholes, film uniformity and screen release on the same artwork. For printed conductors also measure sheet and line resistance; for decorative panels measure opacity, color difference and illuminated-window appearance.
The LICHAO machine provides positioning and print motion; mesh, emulsion, ink and drying must be specified for the project
The LICHAO machine provides positioning and print motion; mesh, emulsion, ink and drying must be specified for the project. Changing ink is not a reason to copy the previous stencil settings unchanged.
How do we start a trial?
Provide substrate, controlled artwork, material data, process flow and acceptance criteria. Use representative samples to confirm configuration and process window.
References and fact sources
Original process guidance. Verify equipment fit and performance with customer samples.
Mr. Yang can discuss a trial plan from your film, drawing and acceptance requirements.
