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". (...)
How are you generating the files? Doing image export? Looking that image you have, looks like he wants the solder stop mask layer. In Eagle there are two layers, tStop e bStop. As your design is single sided, I think you'll need just the bStop layer.
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

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 (...)
hi, i have completed my board with single layer successfully.but when i gave the board for fabrication i got a reply that,i need to show pin out for fabrication. i have generated the gerber by setting the design parameter->disply->enhance display mode (all in ON condition). 92408 but he is keep on telling the same messa
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

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 (...)
I'm designing a pcb using Diptrace software on a single layer design, but after routing, I found that there's alot of paths which are not connected. It requires additional jumpers to connect those paths. I've tried to place the components on different places, but it still end up the same. And this is my circuit: 56812
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 (...)

single layer chip capacitors work for high frequencies. You can also make the single layer capacitor yourself but cutting rogers pcb.
Hi, I am designing a single sided pcb,preventing from overlapping i have to add a jumper.when assembling pcb i connect a piece of wire between desired jumpers to make the connections.i want to ask how i add a jumper in layout.
Hi I bought a few MAXII cpld from altera and i needed a programmer so i designed a pcb for byteblasterMV because i couldn't find a ready (pcb), i have made both a dip and smd version (for 74HC244 only, other components are not smd), both single layer. The schematic i have used is from the Altera datasheet, but i have (...)
in Protel 99SE I want to print out single layer pcb bottom layer that is his alone .... how can I be doing it
Hello All, I have my first doubt cleared, Thanks for that well, I got another one, what is the limitation on the size of canvas or rectangle box when i switch to the pcb/Board from my schematic? and how can i print using the Laser printer on Glossy paper for using it as toner transfer method, I mean , what should be the settings for
Hi Aviano, If your pcbs are single layer types, it will not much help i.e. a military version/technology... If the said boards have through metalyzed vias/holes than it has maybe a bad serie of glue, or sorry-your soldering technique is not the best!? You must be sure that the solder temp is correct & you didnt make an extreme mechanical (...)
50 ohms matching is generally OK for SSTL IO-standards, but you should be able to change the impedance matching. It's adjustable at least on the RAM side, for the controller, depends on the device. I can't reproduce your assumed 136 ohms, I get around 100 ohm single ended for a standard 4-layer pcb stack and 5 mil trace. But it's (...)
what if there only single layer pcb trace, i mean the return trace is, let say not there.
0.024" = 0.6mm which is plenty big enough. Even a low quality pcb supplier should be able to manage 10 thou. If you want to autoroute a single sided pcb you should turn off the top layer in the router and set the bottom side to "direction *" - I think I have already said that earlier. You should be able to route it (...)
