November 2021 IPC-7525C 1 Stencil Design Guidelines 10 SCOPE 11 Purpose This document provides guidance for the design and fabrication of stencils for solder paste and surface-mount adhesive. Stencil design for various surface-mount technology as well as mixed technology with through-hole or.

This stencil design suggestion will base on IPC-7525 Rev L that released in 2005 and IPC-7095 Rev A that released in October 2004. Standards Referencing This Book. IPC 3000 Lakeside Drive Suite 309S Bannockburn Illinois 60015-1249 Tel 847 6157100 Fax 847 6157105.

These guidelines detail the differences for tin-lead and lead-free solder paste overprint two-print and step stencil designs. Contribution is from screen-printing process where stencil design plays major role if considered other screen-printing parameters are optimized on which this paper is focused on.

The step-upstep-down stencil is a special development for the adjustment of solder paste quantity fulfilling the needs of placement and soldering. According to IPC design guidelines 7525B there should be 89mm 035 keep-out between the step down and the aperture in the step down area for every 025mm 001 of step height. This paper is set on guidelines to minimize the process complexities and issues in production using above standard.
