We have left with no option here as it is for prototype boards so we need not worry on the cost because we have aleady got money allocated from our authority.So lets see how the things going to turn out on couple of testing we are planned to carry out on the board after assembly.
Thanks to...
Thanks a ton guys to everyone for pitching in and answer my query.I'm in touch with couple of PCB Manufacturers and got the info i needed.Thanks to Fvm for understanding my query and thats what meant in my query though.Anyway here in india trace width is considered in mils(1 inch=1000 mils).
As...
Thanks a ton for your prompt reply,do appreciate.Yep I did try gathering some info on that.However trace thickness varies according to the PCB Manufacturing capability and I was curious to know from this perspective from different region globally.
You did respond to me on info for the copper...
Hey,Again it is like your previous question,the time you take to post your query here instead bit of research in this forum and bit of googling you had answers in tons to your query.
Just check this link https://www.edaboard.com/threads/88988/ hope it is helpful.

Hi,
Since you say its for a prototype purpose only then you can do little bit of research before you zero in, other thing you haven't disclosed about the layer counts, that also matters.
Hence before researching note the requirements upfront and then start your search.
Thanks and Best...
Hi,
It again depends upon the design, ie complexity,application etc. for simple kind of designs, like for instance power supply design, Pads Layout is the best.
if the design is bit complex, have more connections then go for Allegro.
While posting your query be very specific, like the...

Hi,
Firstly google search,you will get tons and tons of document related to it,go through it.
If you have query,post it here in this forum,someone shall answer ur query for sure...
You can't learn signal integrity over night anyways.

pdf to schematic converter
Hi Folks,
I have schematic in Pdf form,now i need to capture the schematic in orcad cis ver 16,i had asked for Bom,datasheet and netlist for the same from the concerned person,but then he denied.
Is there any way to convert the pdf to schematic form or am i missing...
Hi Folks,
it always depends on what kind of board you design and accordingly one can go for autorouting,for instance,i always route critical signals and protect them first and later i give other non critical signal for auto routing,by doing this you can save lot of time.this is how i proceed...
Hi Folks, We recently migrated to Allegro ver 16 from Pads layout 2005 spac2,we could able to convert the Pads pcb design file to Allegro,the pcb file is 4 layer,later we extracted all the footprints in separate folder and set the path in the user preferences.
Now while i try to compile the...
direct connect与relief connect
Hi,
A wagon wheel-shaped relief pad etched in the copper of a ground plain around a through hole. It connects to the plane through one or more narrow track across an opening in the plane, rather than connecting directly to the plane, so that heat transfer to the...
