Abstract

A stencil for applying solder paste in a desired pattern for mounting electronic components on a surface of a circuit board, said stencil including a sheet having holes therethrough in a pattern corresponding to the desired pattern, a smooth upper surface for receiving the solder paste thereon, and a smooth lower surface for contacting the surface of the circuit board, the upper surface having relieved portions so as to increase the friction between the upper surface and the solder paste being squeegeed thereover.
