First, I believe many people have used DXP draw schematics, but I believe many people only used a maximum of two layers of wire drawing, and some even used only one line only draw PCB diagram, and then the rest of the line jumper.
1, now you might think that only one or two layers of cloth or wire jumper is a very LOW thing! Below I will teach you with a detailed method of fabric four lines, six eight directly follow my method of adding the dielectric layer on the line
1) of 3.3V and FIG implemented with two GND lines not passed through, we can only consider a multi-layer line!
2) It should be noted, Taobao above the playing board shops open only double plate, will not give you a single plate!
2, four-layer board Step
1) is selected in FIG.
2) will pop up the interface
can be seen in the drawing only two PCB, the bottom and top (cell block is two layers)
was added layer 3) Add the following FIG. layer, add twice, and then have a total of four!
4) Upon completion of the name to get rid of, the name changed to need. After the layer is completed as shown in FIG
. 5) shown below and can be seen where two layers of multi-layer, is the VCC and the GND
. 6) can be seen in FIG black block diagram of a display different colors Collage
Speak about the multilayer principle, corresponds to a multilayer board which comprises a multi-layer PCB, more than two layers of front and back, which may have many internal layers, these processes can all be done! And these are not the main problem is to do the more layers, the price will be more expensive!
7) Therefore, four-layer board, the easiest way is to put a layer of the layout of VCC and GND, and then the top and bottom signal line traces! This is the easiest way!
8) placed over the hole, select Net contact layer you want to connect, and then he'll automatically be connected on! Pick 3.3V
can see there is a cross color with respect to VCC and GND is the same,
As long as the line can make life difficult place a via, the vias can be as small as possible, because now the process is achievable! These are not things. Net then to the corresponding layer on it!
3. If you do not want to place a layer of only VCC, that is a waste, as slowly as possible before cable, the corresponding line is to pull out slowly wiring! I do not demonstrate this because this is basic stuff!
Now the board will be four things are written go up! Similarly 6 layers, 8 layers are the same do gymnastics! If you have any questions you can add QQ group: 864 750 551
While micro-channel public number handedly maker culture also periodically publish more information!
The group has much more information! I can see the introduction of other blog
