If I have a six layer LED driver pcb of 6 layers, 2 oz copper on every layer.......... what is the approx. cost difference of having different inter layer thicknesses as follows... 0.4mm thickness interleaving board sections 0.3mm thickness interleaving board sections 0.2mm thickness interleaving board sections
Hello. What would be the cost difference of the above?....4 layer with all through-board vias. (no blind or buried vias) Twice as much cost for 4 layer pcb?..Roughly? You can use the pcb price comparison calculator at pcbShopper.com. You enter the size, layers, and quantity of bo

Look at this, for starters: I'd also be concerned about large variations in your 60 amp currents, which will induce HORRENDOUS noise on your digital lines.
You put them put them on a pcb with heavy (2-3oz) copper and wide traces. Here's a calculator for that. You can also run parallel traces on more than one layer to distribute the current. Alternately you can just solder wires to their

pcb Toolkit all the way..
Got to and download the "pcb Desing Tool Kit. It can do what you want, and a lot more !!!!!!!!!
Hi to all.I want design pcb for 2GHZ to 2.5 GHZ.HOW can I provide 50 Ω for my pcb? w=.24mm er=3.48 h=.8mm T=78?m
Dear All: In the online calculator below, there is an input called Via Length, is it the via height? like, the vertical distance between top& bottom planes for a through hole via. More to ask, what value should I fill for "Applied Current" in Optional
Hi, If i give 12V for a pcb and current passing through it is 5A. This board in turn supplies voltage for some other pcbs. The distance between two end pcb is 2 meters. How much width should i give for a supply voltage track so that the voltage drop is 0.5V between the two end pcbs. 91452 Thanks, Murugesh
How many stitch vias should I add to a pcb? I have added stich vias close to where signals changes reference planes and also near all bypass capacitors. But how many stitch vias besides this should I add? Any web links where I can read more about this? Any books that explains these kind of quastions?
Yes, I am doing that one. Actually, I have finished my desgin and when I do it practically, the pcb technician told me that the gap in my Balun design is quite small. So, I need to improved my design without changing the result. DO u have any ideas? Hi, you need to pass from a umbalanced mode to a balanced one. The bal
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 (...)
Hello all, Does one pair of odd and even impedance correspond to an unique set of w, s, l of the coupled microstrip line ? With the ADS line calculator, the s and w sometimes is smaller than 0.1 mm it's too small for hand making pcb! Thank you for helping!!

Derating of current/voltage depends on ambient temperature and pcb material. for further information please refer following link hope this is helpful.
The project was inspired by LINK . In this case, the pcb was made again, because of used Russian lamps IW-6 from an old ELWRO calculator, different AC outlet and
Hi, Just Try "Saturn pcb Design" tool (FreeWare). as i think it can do.
Download this toolkit: pcb Via Current | pcb Trace Width | Differential Pair calculator | pcb Impedance
try tool from saturn Saturn pcb Design - pcb Design Service | Electronic Engineering it wont give you fulll layer stackup analysis but help you to calculate impedance,spacing etc.
There is not that much difference between plated and rolled copper. The Blog ? pcb Via calculator Read the comments at the bottom, there is other info regarding this.
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. What is the best way in controlling the impedance of the pcb substrate since it do not have traces (only pads with (...)
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
The pcb Toolkit has a planar inductor calculator. Saturn pcb Design - pcb Design Service | Electronic Engineering
hello, I want to know how to check the width of the track that supports a value of current flowing through this track in the pcb design ? thanks
Hey guys, I have been told that there exist some kind of standard time used to calculate how long assembly of a pcb would take in general. I have searched on google and all I can find is this manual that cost 1000$, but ofc I am looking for something "open source" aka. free :) Does any of you know these standard times or know where I can find a t
You can try The Blog ? pcb Trace Width calculator or ANSI pcb Track Width calculator Alex
I would recomend going for the IPC-7351 footprints, they are becoming the de-facto industry standard. The viewer is free and will give you all the information you want for nothing: IPC-7351 Land Pattern calculator and Tools

Hi, Can anybody recommend a good tool for pcb signal integrity analysis?
Im currently designing a pcb with GPS circuit. The GPS antenna stated the signal to have 50ohms. Is the consideration for the line width same as in digital signal. I get thin line width so im confused. Any suggestion would be a great help. Thanks
You have to know what is the Dielectric of the material you are using to get λ εr = ?. If you put those dimensions listed on a pcb w/ εr = 4.3 it might be good, but if your pcb has an εr = 9 it might be way off. Look for APPCAD or go to Rogers pcb website and look for a free web transmission line (...)

Hi all, I found (randomly searched) one side for small projects- for (not only)beginners... calculator complies with ANSI/IPC-D-275 and IPC-2221 design standards for pcb trace width. pcb trace widths are calculated using following formulas; I = 0.0150 x dT 0.5453 x A0.7349 for inte
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
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
Download pcb trace calulator program. Download pcb Design Training catalog too for PADS, Hyperlynx, OrCAD and Allegro pcb editor training.
You can also used Polar calculator but its need a license.. ---------------------------------------------
Hi, Can anyone help me in understanding what is the significance of Electrical Length in designing a microstrip? When I change the electrical length parameter, it doesnot effect characteristic impedance, only the physical length got changed. Then, what is the role of this parameter and how should i take care while designing RF pcb at 2.4GH
Hi I am planning to use a step down converter for one of my application. The IC is LT3693 , Linear make and the output requirement is 5V @ 2A . At full laod, IC generates a lot of heat. Since Ic is MSOP package, a proper heat sink has to be designed & pcb Pad area has to be given as heat sink. The power across IC is 2W. Could anyone suggest me
There are free pcb transmission line 2D field solvers that can be used. TNT ( ), has a good interface and gives good results. MDTL ( ) isn't as well developed, but it still gives good results for differential traces. If all you want are close numbers, and precision isn't requ
Hi I am looking for hi voltage pcb trace clearance calculator Thanks
I wanna know the effective resistance of copper wire on pcb. Since the effective resistance influence the compenstaion of PWM power IC, the copper resistance will generate a zero , but we can't estimate the value, it will influent the stability.

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
