Q:What kind of PCB board is called HDI board?
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 the difference between a single and double-sided package?
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.
Q:How to judge single-sided double-panel multi-layer board
Double board is printed circuit board, printed circuit board, Kunshan circuit board, built and circuit boards, special circuit boards, special circuit boards, circuit board factory, circuit board factory, soft circuit board, soft board, flexible board, flexible circuit
Q:What does the double-sided panel mean?
Because the earliest, the most difficult is the hole in the copper (how in the copper wall of copper without copper), this is the distinction between the double-sided, single-sided the most important basis.But the double double-sided, but both sides of the copper, but the hole
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:PROTEL99 PCB double panel how to draw
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. Click the check box, so that check box appears in the check mark "√" to open the work level. According to what you said you are painting the bottom is not convenient, then you will 'Top' in front of the sign "√" removed on the line. Need to check again.
Q:Pcb double panel if there is a simulated ground and digital to the two to be split?
so if you can see the PCB plane a number of areas of copper, and the area by the inductor or resistor connection, it is likely to be different.
Q:When drawing pcb diagram how to judge whether the single or double panel
When you are in a wire, you double-click the pop-up dialog box to select the layer where the wire is located
Q:Protel do PCB circuit board, how to make the back of the double panel also has components
double-sided patch, single-sided plug-in can be a side of the solder paste, solder paste surface through the reflow, while the paste surface paste, the other side of the red patch, red plastic face plug foot,
Q:Protel DXP how to draw double
L out of the board dialog box, the bottom of the hook is not the bottom and the top of the double panel! But have the layout and wiring!
