Abstract

A method of printing a solder paste formulation onto a substrate surface through a stencil wherein a lubricant additive is included in the solder paste formulation in order to improve the release of the solder paste from the stencil. The method of the present invention provides an improved release of the solder pastes from a stencil during printing and is therefore of particular use in fine pitch stencil printing.
