Step-Up Stencils with the StencilLaser

Nov 21, 2013

LPKF Presents Spot Welding Process for Stencils.

A step stencil is an SMD stencil made with local depressions (step-down) or raised areas (step-up) to allow the solder paste volume to be varied locally. This allows for mounting of both SMD components with a low pitch and robust connection components on PCBs in a single step.

Polished section of a step stencil: The step-up region (yellow) lies within a step-down zone – a design that is useful, for example, for QFPs with heat sinks.

In a newly presented study, LPKF investigates the suitability of the StencilLaser G 6080 and defines the parameters for a reliable process window. The foil reinforcements are applied by spot welding to yield local total material thicknesses of up to 200 µm. The results of the study are available for free on the LPKF website at www.lpkf.com.


LPKF Laser & Electronics AG manufactures machines and laser systems used in electronics fabrication, medical technology, the automotive sector, and the production of solar cells. Around 20 percent of the workforce is engaged in research and development.
