Overview

Maxell has a special two-layer electroforming stencil “AVP stencil®” that can freely control the ink delivery rate. It is a unique stencil that enables appropriate placement of the mesh part with a two-layer electroforming structure.

Release: August 19, 2021

Features

In the conventional method using emulsion stencils, the difference in the position of mesh intersection for each pattern causes the variation of ink delivery amount. Maxell's electroforming stencils have a special two-layers shape that aims to control the amount of ink delivery by placing the mesh intersections in the same position for each pattern. This structure reduces the variation of the ink delivery amount and enables high-precision printing.

  1. Excellent printability due to superior cross-sectional shape.
  2. The mesh opening is larger than the pattern opening, improving paste filling performance.
  3. Free mesh arrangement enables control of ink delivery volume.
  4. Excellent aperture size (dimensional accuracy of ±2µm, depending on conditions)
