2 Introduction

We want to fill an SMD stencil with as many PCBs to make optimal use of the space.

The top and bottom cream layers together with the board outlines are exported through Eagle as CAM job and then processed with gerbmerge and manual absolute placement to create one combined gerber file that can be sent to an SMD stencil manufacturer.
