Transition Automation Introduces New Permalex S Series

Transition Automation, Inc. has announced an expanded Permalex product line, with the introduction of the S series.  This new product line is specifically designed for aqueous solder paste formulations, which have aggressive chemistries that are not compatible with the standard E series (Blue Spring Steel) version.

This new series is developed from a high grade of stainless steel that is harder than the stainless steel often used for stencils and squeegees. This product is ground sharp – polished at the edge – and coated with the Permalex Teflon metal matrix.  

“We maintain all the aspects that make Permalex products highly durable for mission-critical SMT printing. This way, customers are getting a nearly identical product, except this version can be used in highly alkaline paste chemistries as well as in high humidity and tropical environments,” states Mark Curtin, Technical Support Manager for Transition Automation. 

The product shares many of the high-reliability aspects as the standard Permalex E series, including precision grind-polish-coat, laser part number and date code marking, and hermetically sealed, clean dust-free packaging. To order the Permalex S series, customers may simply change the common product code “E” (or “W”) to “S”.  

Permalex S series is a stainless steel, high hardness and high yield strength alternative to Permalex E and is available immediately for any SMT printer platform. Permalex S may be ordered with Universal Holder Assemblies or as bare replacement blades, or blades with holes, and/or with bends for intrusive printing.

This item is available immediately, with a delivery of seven days or less, and may be purchased on the company’s web store at
