Cookson Launches Laser Cut Nickel Stencil Line
South Plainfield, NJ — Cookson Electronics Engineered Products, an Alpha, Cookson Electronics business, has launched the Alpha® nickel line of high performance laser cut nickel stencils.

The nickel stencils are designed and manufactured to provide full and half-mil stencil thicknesses for better critical aperture printing, hard nickel for wear resistance and excellent positional and size accuracy, particularly when used in conjunction with the company's solder pastes.

The stencils reportedly offer flatness and low internal stress; unlike rolled stainless steel, the electroforming process produces hard nickel blanks of low internal stress. Because of this, the stencils have superior flatness and maintain the flatness even in areas of high aperture density.

The laser cut nickel stencils can be produced in half-mil thickness steps — 4.5 mil (110µ) and 5.5 mil (135µ) in addition to the standard whole mil thicknesses. Thickness is the most important variable impacting paste transfer efficiency, and the ability to tailor half mil thicknesses — not available in standard stainless steel laser cut stencils — provides much greater latitude in controlling paste deposition than is available with traditional stainless steels.

The PCB contact side surface is made mirror smooth for faster and easier cleaning using manual or automated underside wiping.
