Hi All, I have just gone through Saturn pcb calculator for calculating current carrying capacity of traces. But I doubt how accurate is it, as it gives almost same result for Internal and External Layer traces. I underastand that no calculator can give exact results but from my previous experiences I think there has to be some (...)

A good online tool for pcb Trace width calculation. Thanks, Nerv
I have find on Thermal Man(agement) site. Many information on temperature rise, of pcb traces, very interesting, with a FREE calculator (limited to I*P*C* 22*21). And some information on I*P*C* 2*1*5*2. It's all at the moment, if some-one have other information please reply or PM. Skywalker.

Hi all, I am looking for a pcb footprint of the dsPIC30F6014. The datasheet defines it as 80 Pin TQFP. I use Protel 98 for my schematic and pcb development. Regards Rahul
I would not recommend using the UltrCad differential impedance calculator, bought or otherwise - for some reason it is based on the flawed theory that the separation between the +/- legs of a differential pair have no bearing on the impedance - a highly disregarded theory, based on an assumption that a stripline trace represents essentially the sam
Hi all, anyone know of software that can calculate impedences, and details (e.g trace width, pcb thickness) when u input RF details e.g frequency etc
Rfsim or appcadcan help you. Some of pcb tools can do impedance routing for yoe e.g. protel
hi. who uses high frequency dielectric materials for high speed pcb designs, who dont, and why? in an AMD appnote they use standard FR4 for a board, where the highest speed bus is 400MHz DDR memory bus. for a same speed board, intel uses some HF material, with Er about 3.2. In the appnote, they tell the width and thickness, 4/5 mils. they

Hi, Is there any single tool which has Power rating calculator (Via, trace), Impedance calculator, Cree page, IPC foot prince calculator (IPC 7351), and CAM view. Basically I want all pcb related software in one tool. Regards, N.Raghavan
Hi, Does anyone have an idea what is the (very) high volume (100k+) price difference between six layer (4Sig, 2planes) vs 10 layer (6sig, 4 planes). Or, any web based calculator (haven't had luck locating one) for high violume pcb. I am inclined to try with 6layer, but then the traces must be 4mill and not well protected, I am facing EMI/EMC iss
I am a newbie in RF pcb (LAYOUT) design field. I only know about the impedance calculation of the straight micrstrip line. Please help me about how to start learning the RF pcb design, consideration of bendings, effect of impedance by bending of track, how to design layout when high freq and low freq are together in the same pcb, etc. (...)
can anybody tell about constraint manager for pcb of 4 layer - prepeg thickness,fr4,copper thickness.etc.,this is for get to impedance controll on the tracks(selected ones). i hope you will help in this matter.
Hey, I have a board that have some signals, that will have non repetitive pulses of 8A 20 mSeg long. The problem, is that my board don't have enoght space to use a 150 mils or more to meet the 8A current in average mode. Do somebody has a I2t (current vs time) formula for the widht of trace in pcb?. Do somebody has s

I have to design the layout of an embedded device with bluetooth interface. I use an STM bluetooth module and an antenova Chip Antenna. In this contest, I have to design the Antenna Matching Circuit to adapt the Impedance value between Antenna and Module. It is very important to calculate the Impedance value of the trace that I have routed from

Hi, I am looking for information about low to medium volume pcb assembly cost in Asia where the components mostly SMD. Considered low volume if the board qty < 1000, and medium volume if the board qty is above 1000 and up to 10000. Searching the web didn't give enough clue, hoping someone with real experience will share. TIA, Ichan.
Hi. I am trying to make an inverter circuit. The thickness of copper on my pcb is 35 microns (.035 mm).. to carry a current of 12 A how much should be the track width.. The base material for the pcb board is glass epoxy .. any precautions to be taken for this current level ?

Wider the trace, lesser its impedance, hence higher is the current flow. Similar thread was discussed in EDA board on The Blog ? pcb Trace Width calculator . Also I found following links to be very useful in calculating track width for a desired
Hi,ark I used some calculator which shows that if I use 2 oz. copper, I need 7 mm. That would be too wide. If I used even thicker copper, I'm afraid that I would be not good for other trace, or unless we could design the thickness of copper for certain trace? would it be a good idea to use 2 oz. copper with 1mm width and cover it with solder layer
Hi, I am designing a pcb substrate (FR4 with 1mm thickness) to place 4 pads chip on top, and then it has a thru hole connect to the bottom layer of the pcb, and the pcb will be mounted on a flex circuit.

Hello. In pcb design ... I am quite confused about determine pcb clearance. Generally my default Signal lines are 10mil Trace Width and 10mil Clearance. Now what Clearance I need to use for a +12V Line which may draw max 3A? I set 40mil Trace Width for this high Voltage Line, is 40mil good enough to pass 3AMP? Can anyone advice me ... abou
