Pcb Layout Calculators

[blackstick.co.uk]

Hi Guys,

Please feel free to download our C4 calculator which includes a voltage gap calculator and a current carrying capacity of tracks calculator.

Do you need to know how far your tracks need to be apart for a specific voltage? Our calculator will tell you the gap required and also lets you choose different altitude levels.

How much current will my trace / track carry?
We have a calculator for you too, coated or uncoated tracks internal or external the C4 calculator lets you alter it all to suit your current carrying needs.

All of the calculations are based on the IPC 2221-A, and best of all it's FREE.

Download the C4 calculator HERE (http://www.blackstick.co.uk/resources.html)


Also we are going to release V2 soon which will include a via current carrying calculator, so subscribe to the calculator updates and be the first to get the updated version.

Just to let you all know. The above calculator will now allow you to work out the current carrying capacity of a via (or other hole).

As promised :)

Any suggestions for further improvements are welcome.

Hello, This great little calculator program from Rogers Corp will:
calculate Zo (characteristic impedance) of Microstrip, stripline, and Offset Stripline (Asymetric Stripline)
Design couplers in stripline.
Since MWI works for asymetric stripline, it is the most capable free package for digital PCB transmission line design.
The user interface is very efficient, but it doesn't have the familiar Windows look and feel.
Rogers corp is in the business of making PCB substrates for microwave circuits, so some of the jargon used
may be new to high speed digital designers.

The above current carrying calculator, certainly safe to use, will shortly be obsoleted by a new IPC spec - I believe there is an article on www.pcdandm.com - in the magazine accessible online.

It was in the July issue - the new spec. will be - IPC-2152

Hi Guys,

We are working on updating the current carying calculator to the new IPC spec IPC-2152. We are also in the process of making the calculator web based so that there is no need to download it.

Would the option to make it a download, as well as being online be advantageous? Or is an online version better all round?

Hihi....

I met a big problem because I don't know how to operate for the program of CAM350.

My question is :

1). where & how to check the line width/space of line?
2). how to know the X to Y from point->point

Actually, I want to have an INDEX for guidance how to use the function of this software function, anyone can help?

Hi, Juli:

You can see the toolbar, and the click the "info", you can see the "measure" tooling, I think it's okay for you now.

Interpreting IPC-2152 in a way that makes sense
(from a calculator point of view) is not easy.

This may help:

Your explanation, (on the web site), is inexplicable, "back when the chart was published there were no multilayer boards", then why would anyone need a chart for them, I think the truth was that there were multilayer boards but no standardized method of construction - back when I entered the business in 1972, (I was 5 at the time :) ), I saw many 4 and 6 layer boards, one in particular I remember was a board built by the Bureau of Engraving, that was called a 4 layer board but in all actuality it was pads only outer 6 layer, funny thing was you could see right past the signals on layer 2 to the pink power plane, (no oxide), with no visible weave, other pressfit backplanes were made by pinning double sided boards together with sheets of copper sandwiched for power planes - not reliable since drill data and machines weren't all that great.

Sorry for the critique, I really do appreciate the calculator!

On second thought there were probably no military multilayers, back then they were still using wire wrapped laminated metal plates with plastic connectors pressed in.

[Jack Olson]

The historical chart was developed in the 1950's, and did not contain the section for internal traces, since there were no multi-layer boards at the time.
The internal chart was added many years later.
I don't know if I would call that "inexplicable", but I added the line "The internal chart was added many years later" to the text for clarification.

Thanks for pointing out how readers could be confused by that.

Hi,
it's very great informative stuff shared here useful one for many others who needs this kind of stuff,…
i appreciate this effort,..
best regards,..

I don't think Alan's too interested in hairstyles - he's no hair left!
I think it all fell out as he tried to get a grip of IPC 2152! lol

Just like the rest of us then, eh?

I'll have you know I still have a thick and glossy coat of hair.

And a wet nose.
