Q:What is the most important difference between the PCB board and the second floor?
The simplest difference is that the four-story board has an inner layer and the second board does not.
Q:What about the double-panel cabinet?
Double decorative panel surface smooth, because the plate double-sided expansion coefficient of the same and not easy to deformation, bright colors, the surface more wear-resistant, corrosion-resistant, affordable. And can imitate a variety of patterns, bright color, for a variety of wood-based panels and wood veneer, hardness, wear resistance, good heat resistance.
Q:Protel DXP how to draw double
Execute the menu command [Design] / [Options], the [Docunent Options] dialog box appears, select the Layers tab to enter the dialog box at the job level. There is a check box in front of each working level.
Q:What is the difference between them and ordinary double panels?
It is modular in parallel design, a module capacity of 1000VA (height 1U), natural cooling, can be directly into the 19 "rack, the largest parallel 6 modules. The product uses all-digital signal process control (DSP) technology and more
Q:How do you make a double panel with fiberglass?
The use of glass fiber is increasingly widespread, its unique and diverse performance makes it a powerful material. Whether in the medical, communications or industrial areas, have its shadow.
Q:How to judge single-sided double-panel multi-layer board
Because there are many strict restrictions on the design of the single-sided board (because there is only one side, the wiring can not cross and must be around the path), so only the early circuit to use such a board single-panel wiring diagram to network printing Screen Printing), that is, on the copper surface printed on the resistance agent, after etching and then to the resistance to print on the mark, and finally to punch processing to complete the parts of the hole and shape.
Q:PROTEL99 PCB double panel how to draw
To set the design rules, click Rules under the Design menu, open the Rules tab, click the NetsTOIgnore network under Placement, and select the network that you want to ignore.
Q:My PCB in the power supply should be a single panel or a double panel
This look at your frame size, the components can be a good down, single-sided alignment is easy to walk through a single panel, bad walk on the use of double-sided.
Q:When drawing pcb diagram how to judge whether the single or double panel
Drawing board is not a judge, but choose a single panel or double panel. Because the price of a single panel is much cheaper than the double panel, so there is no special requirements will try to choose a single panel. But if the alignment is more complex, single-sided can not be achieved when the use of double-sided, or even multi-layer board.
Q:Pcb double panel if there is a simulated ground and digital to the two to be split?
they and digital ground will be used inductors or 0 ohm resistance or other means connected to a single location. Some of the analog and digital ground of the PCB is divided into copper,
