It is used to mark the projection outline of the components, the label, nominal value or model of the component, and various annotation characters. The color of the silk screen layer is generally white, which is mainly used for printing information, such as the outline and labeling of components, various annotation characters, etc., to facilitate the soldering of PCB components and circuit inspection. Same as the signal layer, the internal planes and the internal planes, and the internal planes and the signal layer can be connected to each other through vias, blind vias and buried vias.Ī PCB can have up to 2 silk screen layers, namely Top Overlay and Bottom Overlay. The number of PCB layers generally refers to the sum of the signal layer and the internal electrical layer. This layer only appears in multilayer boards. The power cord and ground wire are not included here. There can be up to 30 layers, which are used to arrange signal lines in a multilayer board. For double-layer boards and multilayer boards, components can be placed on it. ![]() For double-layer boards and multi-layer boards, it can be used to arrange wires or coat copper.Īlso called the solder layer, it is mainly used for wiring and soldering. The layers can be connected to each other through vias, blind vias and buried vias.Īlso called the component layer, on which components are placed. Altium Designer can provide up to 32 signal layers, including Top Layer, Bottom Layer and Mid-Layer.
