Stork Graphics has recently introduced the HiMesh Mask specially suited to surface mount technology applications. This screen printing mask, made of 100% nickel, differs from metal masks and traditional stainless steel or polyester mesh in that it encompasses many of the advantages of both. It has the flexibility of a steel or polyester screen combined with the typical stencil qualities of zero deformation and dimensional stability. The hexagonal structure, and therefore the wall and hole shape, means that both on and off contact printing are possible. Additionally, this material provides a very uniform and flat deposit, an essential criterion in the application of solder paste.
