PCB Delamination

(1) Signal the Layers (layer Signal) : the copper foil layer, used to complete electrical connections. Altium Designer Winter 09 allowed 32 Layer signal, circuit board design, respectively, for the Top Layer, Mid Layer 1, Mid Layer 2... 30 Mid Layer and Bottom Layer, each Layer with different color display. (2) Internal Planes (the middle tier, also called Internal power supply and ground layer) : also belongs to the copper foil layer, is used to establish the power and ground network. 16 middle tier system allows circuit board design, respectively as Internal Layer 1, the Internal Layer 2... Internal Layer 16, the layers with different color display. Layer (3) Mechanical the Layers (Mechanical) : used to describe the circuit board structure, annotation and processing machinery production and assembly information such as the use of level, can't complete the electrical connection in the feature, but its name can be defined by the user. System allows PCB design contains 16 Mechanical Layer, respectively Mechanical Layer 1, Mechanical Layer 2... Mechanical Layer 16, the layers with different color display. (4) Mask the Layers (layer resistance welding) : used to protect copper wire, also can prevent welding error. System allows PCB design contains four resistance welding layer, namely the Top Paste Paste (Top Solder Paste protection layer), the Bottom the Bottom Solder Paste (protection layer), Top Solder Solder (Top) welding layer, and Bottom layer (the Bottom resistance welding), respectively displayed in different colors. (5) the Silkscreen the Layers (silk screen layer) : also known as the legend (legend), usually the layer is used for place component symbols, words and symbols, and to identify the parts in the position of the circuit board. System provides two silk screen layer, namely the Top Overlay (Top silk screen layer) and Bottom Overlay (the Bottom screen printing layer). (6) Other the Layers (the Other) 6-1) Drill Guides (hole) and Drill Drawing (drilling) : used to describe drilling and drilling position. 6-2) Keep - the Out Layer (Layer ban wiring) : used to define the wiring area, the basic rule is components cannot be placed on the floor or wiring. Set up a close range of wiring, only here to start the component automatic layout and automatic line function. 6-3) Multi - Layer (layers) : this Layer is used to put through the multi-layer PCB components, is also used to show through the layers of machining instructions.http://pcb.hqew.net/?s=544864 Click the menu bar of the "Design (Design)" - > "Board Layer & Colors... (circuit Board Layer and color)" command, in the "View Configurations (View)" dialog to cancel the middle three check boxes checked to see the system to provide all of the Layer.
