The PCB project generally contains four files: XXX.SchDoc(PCB schematic diagram), XXX.PcbDoc(PCB packing diagram), XXX.SchLib(PCB schematic diagram), XXX.
The general process is as follows: first draw [PCB schematic library SchLib], then draw [PCB encapsulation library PcbLib], and associate the schematic library components with the encapsulation library.
Then draw [PCB schematic diagram SchDoc], and update it to [PCB encapsulation diagram PcbDoc], design-> updatePCB Document, and finally make copper wiring.
I. integrated library production
Make integrated library (schematic library, PCB package library, PCB3D library), add components to schematic diagram, import PCB, PCB design and wiring, 3D preview
1. Before placing pins, press TAB to set attributes and rotate by space
2. Designator is the pin flag, corresponding to the PCB wrapper library pin. Tools-> model management associates the principle library with the PCB wrapper library
3. Underline AB on the display
2. Add 3D library
3. PCB schematic drawing
Tools – > Annotate Sch.. ->Update Changes List -> Accepted Changes automatically adds notes to eliminate the altium designerduplicate part error
4. PCB board drawing
Automatic wiring :Auto route-> All.
Check rules: tool-> Design Rule Check.
Place – > Ploygen Pour
The Top layer and Buttom layer are both laid. Note that when laying copper, choose the ground GND(the ground wire is not connected when wiring).
Note: in the second mode, the line width should be 10mil, otherwise the rule cannot be checked
PCB package library updated tools-> update PCB after modification.
Update the schematic diagram tools-> update Sch.
Design->update PCB Document
The execute changes – > validate changes
Set board shape:
Draw border lines, shift key selection
Design->Board Shape->Define Form selected objects
The board turns grey -> right-click ->Filter->Clare Filter
Set electrical boundary:
Switch to the keep-out layer and the place-> Line will be produced according to this shape.
The electrical boundary is used to limit the extent of wiring and component placement by drawing the boundary in the Keep Out Layer. The prohibited wiring layer is a special working layer in the PCB workspace to determine the effective position and wiring area. All signal layers are restricted to the electrical boundary.
The Q key realizes the conversion between English and metric units
Two side placement components:
Method 1: while dragging the component, press L and the component will automatically go to the bottom layer.
Method 2: right click to view the property and change the Layer property to Bottom Layer.
To hide GND network, it is common to connect GND when pasting copper, so it will be more relaxed to hide GND connection when drawing PCB connection. The shortcut key n-h-gnd will click GND welding plate, and it is ok to pay attention to applying copper grounding, otherwise the whole board will be scrapped.
