I am doing single rank ddr3 routing in a 6 layer board with the following stackup:- Signal(L1) -> Gnd(L2) -> Signal(L3) -> Pwr(L4) -> Gnd(L5) -> Sig(L6) (I am using Saturn pcb Toolkit for calculations) Via 1 (L1-3) Via 2(L1-6) Height of Via 12 mil[/td
The appended dxf is useless because it has all data in a single layer. pcb layout data must have separate layers for each copper layer (apparently 1 in your design) soldermask(s) silkscreen ("marking") board outline drills Drill data must be probably manually converted because a file with x/y (...)
What print option should I use (mirror,not mirror) for making pcb single layer using photo etching method? for example : - components are on top silk - blue layer is bottom copper 130624 Options: 130625

A standard 6-layer stack is using 2 cores. single core would be used in a sequential process for buried vias. Manufacturing steps for standard 6-layer are - etch both (double side) core substrates - assemble, press and cure complete stack (copper foil - prepreg - core - prepreg -core - prepreg -copper foil) - drill - through-plate (...)
Check if your university is capable of making its own boards. If so, you'll have to etch it yourself so try to make it single layer, and use jumper wires where necessary. In that case, use through hole components and route the traces on the bottom layer. If they're capable of making double sided boards (same process but need double sided (...)
The cost of any circuit board in volume is always proportional to the total weight of copper used in the panel. This becomes a product of the weight per area and number of layers of each. E.g. x cents per oz per Thus a single layer is always cheapest, but must be designed to distribute power and signals with necessary shielding (...)
I have this via structure, It looks like its throughhole but I don't see any clearance/isolation area with other layers. Is that means it's touching and connecting to every single layers? It doesn't make sense. If it's a via to ground then its touching the ground plane and clearance/isolates with other layers. (...)
Hey guys I am making a arduino mega (2560) shield which consists of 4 dip ICS and some capcitor and 4 (8pin row)screw terminal ,so im using basically all through hole packages soldered on one.The problem now is that the circuit is big so it cant fit on a single sided board, so I have to build double sided board which I tried but have following dou

First of all, I'd use a four layer board, not two layers; you're just asking for trouble otherwise. Keep your analog and digital components separated. For ground plane, what I usually do is use a single plane and add cutouts to separate the analog and digital circuitry. Do a google search of "pcb layout guidelines". (...)
i have done design in eagle. so i decided to to give to make pcb. This is my first time so i don't know how to genrate require files to make pcb. after contacting manufacturer he told me too give three files film. Silk layer, Bottom layer, and pad file for single side pcb. i have genrated (...)
Could you post a schematic of your circuit? From what I understand of your pcb, RB1 is floating, there is no external pullup, only a couple of connectors for LEDs and sensors? What value has the resistor in series with the Vdd supply to the PIC? Is this a single layer pcb? Have you got a datasheet of your sensors?

ya, you can do the single side board in allegro also,for single side board you need to route the trace in bottom layer.
Hi all i have an eight layer board. i used 1 cdce as clock. by the way i used 2 ADCs too. the impedance of my lVDS signals is 100(ohm). i have some single ended signals like SPI_MISO, SPI_MOSI,.. . what is the typical impedance of these traces? help me tanx
hi, you can do single layer board in altium.don't route any signal in top layer you should route in bottom layer only.For Fabricator you should send Bottom layer routing ,Top-Silkscreen,Soldermask bottom and Drill table it is enough.
Hi, How to calculate required trace width for single pulse of 45A for 180us duration. In my pcb I have 115mil trace on outer layer with 2oz copper and now we want to check that this trace can withstand for 45Amp current 180 micro second. or how much time it can withstand for 45A. Regards, Atul
I have an instrumentation amp circuit similar to that shown in this appnote but with the first stage of the instrumentation amp made out of discrete opamps. The layout has to be done in a single layer (except for the power) with the GND plane. I am concerned with rout
hello i'am trying to design a pcb for my led matrix , i'am using 5x7 matrix from lite_on(datasheet is linked below) and i want to palce 4 matrices,i'am using ARES to design the pcb on a single layer but i have a problem when the routes cross each other what should i do ?96314
Hi I am trying to design a spiral inductor on my pcb. I have a space of 10mm x 10mm for it, the good news is I also have 8 pcb layers to achieve it. There a lots of formula's for a single layer spiral inductor available on the net, and by above dimensions I can only achieve about 2uH with 20 turns with (...)
I don't think that "pin out" is a clear term related to pcb. Which information is missing in the gerber data? I presume you are talking about pcb fabrication, not assembly? Necessary files for a single layer board are - signal (copper) - soldermask - board outline - NC drill
I have an issue with ADS Layouts. I want to generate a Gerber File of two pcbs in a single panel. How should I specify the panel boundaries, the cutout layer, and the solder mask layer? You can export your ADS file as a DFX, then Import that DFX file in to a pcb Layout program, and do you partitions in that p

I design pcb (single/Dual layer) using CadSoft Eagle, looking for work/projects.
Wow - good luck! single sided, not a chance. Likewise double sided. Are you going to have the board made for you, including component placement, or are you intending to make it yourself? If making a break out board you will have over 30 inches length in 0.1" header pins to place. I would guess that at least a 4-layer board would be need

Hi all, Engineers who are familiar with HyperLynx please help solve stackup problem in HyperLynx. I'm getting stackup problems message when trying to simulate a one single net in my pcb. My pcb board has 2 physically layer only. But when trying to simulate a got warning message "The stackup has error". And when I opened (...)
When you press the boards, the dielectrics will touch and it will look like a single piece of dielectric to EM waves. The minor discontinuities in the dielectric will barely affect the dielectric constant. As for the dielectric thickness, you should look at the overall thickness dimensions placed on the pcb and use that to help you estimate the t
HI; I am using Proteus7.1 sp2 for my pcb design; i can't find any jumper in its library. i want to include 1 inch or greater jumpers in my design/layout to prevent cross wiring and overlapping. can any one please guide me about that? Thank you
by default it is been created as double layer pcb layout. but i need it for a single layer. can anyone help me with it
I'm currently working on my senior project for my EE degree and I am designing a pcb that requires a bipolar power supply. Currently my pcb design (version 1, with a single ended power supply) has 4 layers, the middle being power and ground. The power planes are split into analog and digital planes as well, as noise is of (...)
There is no magic way to autoplace the components in the best possible position, the autoplace does it kind of randomly so it is better to place them manually by looking in the connection lines and then try to route the board and move or rotate components to help routing. There will still be cases where a single layer routing will not be possible
Green masking is not recomended for hobby pcb fabrication as it requires print-out of a solder mask layer to be applied to the pcb. Screen printing is usually used for the same. Regarding pcb raw materials sourcing in chennai, you may refer local yellow pages or take guidance from a commercial manufacturer. For preventing (...)
convert the pcb to single sided double layer pcb's are horrible from servicing point of view, i have not been able to remove a SMPS transformer from a double sided board as yet

If the layout is in single layer go for 1mm track and how much current fllows in that track u have to look this also.1a you have to draw 1mm thickness and if it is 2layer u can go 0.5intop layer and 0.5in bottom layer
I am new to orcad pcb editor. I am designing a circuit on a single layer substrate, i.e top copper/substrate/bottom copper. I want to place the components and most of the routing lines on the top layer but few routing lines will be in the bottom layer. The rest of the bottom layer will act (...)
A brief look on your design clarifies, that it can't be fully routed on a single layer with the present technology (trace width and spacing). Furthermore I notice, that it has exactly one bypass capacitor (near the voltage regulator) and none at other chips. So there may be serious doubts, if the circuit is working reliably this way. Ther
First, are you sure something is really wrong? I would generate and examine Gerber files before I was convinced there was no copper there. Altium's 3D view (with the Power layer selected in single layer Mode) should give you a good view, but I have seen cases (on Soldermask, also a negative layer) where Altium's display (...)
it is too simple you can learn it from this tutorial make shematic in protues press ARES tool in tools bar make arrangements needed and finally make auto routing you can watch this tutorial YouTube - Auto Routing in single layer - Proteus Isis and Ares
A stripline circuit uses a flat strip of metal which is sandwiched between two parallel ground planes -from Wikipedia. It means that it is better if you can connect 2 parallel ground plane using lots of via. multi layer pcb usually have multiple ground plane. In case of 4 or 6 layer pcb that only have (...)
