Q:On the PCB shop copper problem, if it is a double panel, is not also do not have to layout the ground, both sides of the shop copper, and finally casually playing some holes?
After a long time to understand that those holes are stress, but in the ordinary low-frequency board is not so strict requirements only
Q:What kind of PCB board is called HDI board?

Q:How to draw a double panel
This is not all automatic routing, two layers are selected, when the wiring will automatically wiring ah, and then found the top layer, and the underlying color is also different.
Q:What is the difference between them and ordinary double panels?
Common printed circuit boards are made of low-end materials, such as: paper substrate, composite substrate, epoxy board (also known as 3240 epoxy board, phenolic board), FR-4 glass fiber board (puzzle plate)
Q:What is a single panel and a double panel? What is the difference between them?
Refers to the light board attached to the circuit board. Single-sided board is a copper wire alignment; double-sided board is 2-sided. The material is generally double-sided. Some of the single-panel is cheap flame retardant board, the above electrical performance is good. Conducive to heat. high cost
Q:Pcb double panel if there is a simulated ground and digital to the two to be split?
The last question, that is, when the shop in the copper, set different types of land, respectively, covering the different needs of the above.
Q:After the schematic is imported into the PCB, after layout and routing, it is a single panel. How to draw a double panel? Specific steps also please prawn guide, thank you
The default settings, after the introduction of two lines, toplayer and bottomlayer, respectively, the top and bottom. Respectively, in the two layers of the line, that is, 2-layer, if only in which a layer of painting, is a single panel;

To
Q:What is the difference between a single panel and a double panel?
The panel is on the most basic PCB, the parts are concentrated on one side, the wires are concentrated on the other side. Because the wires only appear on one side, we call this kind of PCB called single-sided.
