The two layers of topsolder and bottomsolder are just opposite to the previous two layers. Toppaste and bottompaste are the bottom pad layer on the top layer, which refers to the copper platinum exposed to the outside (for example, we draw a wire on the top wiring layer, and what we see on the PCB is just It's just a line, it is covered by the whole green oil, but we draw a square or a point on the toppaset layer at the position of the line, and the square and this point on the printed board are not green It's oil, but copper platinum. Topoverlay and bottomoverlay are the silk screen characters that define the top and bottom, which are the component numbers and some characters that we generally see on the PCB. That is to say, after we first define the forbidden wiring layer, in the future wiring process, the wiring with electrical characteristics cannot exceed the forbidden wiring. The forbidden wiring layer is the temporary boundary of copper that defines the electrical characteristics of our wiring. In fact, when we talk about the mechanical layer, we mean the overall appearance of the PCB board. The mechanical layer defines the appearance of the entire PCB board. This will not happen after placing graphics on the Michanical layer.ģ. MultiLayer can be called a multi-layer, the graphics placed on this layer have corresponding graphics on any layer, and the keepout layer that will not be screen printed on the solder resist is actually not used to draw the shape of the PCB, the keepout layer The real purpose of is to prohibit wiring, that is to say, after placing graphics on the keepout layer, there will be no corresponding graphics copper foil in the corresponding position on the wiring layer (such as toplayer and bottomlayer), and it is all wiring Floor. Michanical is a mechanical layer, used to place mechanical graphics, such as the shape of the PCB Ģ. You can only place the disk diameter smaller.Īs for the two layers of Michanical and MultiLayer:ġ. Just put the via pads of the corresponding aperture on the Michanical or TOPLAYER or bottomlayer layer. When placing positioning holes, you don't need to place content on these two layers. But now most of them are CNC drilling, so these two layers are not very useful. When drilling manually, these two files must be used together.

DrillDrawing is used to view the hole diameter.

DrillGuide is used for guiding drilling, C8051 chip decryption, mainly used for manual drilling for positioning Ģ. The difference between DrillGuide and DrillDrawing:ġ.
PROTEL 99SE MIRROR PCB COMPONENT PATCH
The electronic components of the patch are attached to the solder paste for reflow soldering. The past layer is used when the stencil is made before the PCB patch. You will see bare copper foil everywhere. If the solder layer is added, the PCB will be added here after it is made.

If you do not add a solder layer to the trace after routing, the green oil is added by default when the PCB manufacturer makes it. The purpose of soldering, in fact, is not the case.

To understand it literally, it is to give the traces on the PCB a layer of green oil to achieve resistance.

Simply take the top layer as an example: the full name of the solder layer in Protel 99SE is top solder mask, which means the solder mask layer. It can be said that these two layers are the layers to be covered with green oil, solder: solder, paste: paste, paste, mask: mask, film, surface layer, etc. What we see on the PCB is only It's just a line, it is covered by the entire green oil, but we draw a square or a point on the toppaset layer at the position of this line, and the square and this point on the printed board are not green. (For example, we drew a wire on the top wiring layer. Toppaste and bottompaste are the top and bottom pad layers, which refer to the copper platinum that we can see exposed. The top and bottom pad layers of the PCB circuit board layer:
