Three symbol styles are available: coded symbol, alphabetical codes (A, B, C etc.) or the assigned size. Individual layer pair plots are provided when blind/buried vias are specified. Drill Drawing Coded plots of board hole locations typically used to create a drilling drawing that shows a unique symbol for each hole size at each hole location. Paste Masks Top and bottom masks are provided to generate the artwork which is used to manufacture stencils to deposit solder paste onto surface mount pads on PCBs with surface mount devices (SMDs). Solder Mask Top and bottom masks are provided for creating the artwork used to make the solder masks. Mechanical Layer names are user definable. Mechanical layer items can be automatically added to other layers when printing or plotting artwork. Mechanical Layers Sixteen mechanical drawing layers are provided for fabrication and assembly details such as dimensions, alignment targets, annotation or other details. SilkScreen layers Top and Bottom Silkscreen layers are typically used to display component outlines and component text (designator and comment fields that are part of the component description). Nets can be assigned to these layers and multilayer pads and vias automatically connect to these planes. Internal Planes Sixteen layers (named Internal Plane 1 16) are available for use as power planes. Anything placed on these layers will be plotted as solid (copper) areas on the PCB.

Signal layers There are 32 signal layers that can be used for track placement. Prior to the Design Explorer 99SE, there were up to 16 signal layers, 4 mid layer power planes and 4 mechanical drawing layers. The Placement accuracy on the mils grid system is ± mils. The boards can be as big as 100 inches by 100 inches. There are 16 mechanical drawing layers which allow you to generate fabrication and assembly drawings for your design.

The PCB editor uses a 32 bit design database and can generate through hole and SMD designs of up to 32 signal layers, plus 16 mid layer power planes. In this document, the ASCII PCB file format for Protel PCB 99 SE will only be documented. PCB documents are also saved in a Protel ASCII text format. The default binary format generates a compact database, which loads and saves PCB data efficiently.
