Eagle Layout Help

i need help i have the schemetics but i want some one to tele the schemetics and make a layout for me as short of time left for my demo presenting which is after 12 hrs this is a system about an audio amplifier which runs ultrasonic transducer which include IRF540 MOSFETS , IR2111 Half Bridge and TL494 IC and 7812 Voltage Regulator and some resistors and capacitor the schemetics is ready but learning how to convert it to layout take too much time while i have short time left the schemetics and original diagram is attached. Please tele if any mistake correct them and make a PCB layout for me which can be printed soon

The problem is that there is no bill of material so there is no way to know, for example, what connector to put in the layout.
What is the second file (pcb.sch)

PCB.sch is the Eagle schematic file. If you load it and rum BOM.ULP (in eagle) it will generate the bill of material.

If the schematic is complete he is ready to go to layout.

2P termianls to put in here like attached is one of the top veiwe of the circuit that was made but now its not working thats y i am redesigning it. and pcb.sch is the file that i have replaced the items with like ic4 it was in layout execise a transistor while it is a voltage regulator. so i need some one to make the layout for me.

Why not continue and do the layout yourself ? It takes a while but is worth the effort.

its effort but i have lot of work to do now , preparation of presetation and its learning , learing concepts and making pcb so learnig now will be a bit tough need a layout any one please help :-(

Your schematic design is a desaster!

There are unconnected pins and parts do not have a value which makes it almost impossible to track the errors.

How should one get along with that kind of work if it's not his own design?

Don't change grids using odd numbers! Always use inch based grids and fractions of inches. Changing from grid size 1/10" (2.54mm) to any odd value, e.g. 1.26mm instead of 1.27 the nets will not connect properly.

Error tracking can be made by using the eye-symbol to highlight every net from beginning to end with all pins which should be connected. If one pin is not highlighted it won't be connected on the PCB layout.

Additionally the voltage regulator and all power MosFets are horizontally arranged (instead of vertically) on the PCB taking up a lot more space than on your photo.

Most of the capacitors used are tantalum type caps. There are lots of ceramic caps on the photo, but none in your design.

What's the second 8pin DIP IC?

Sorry, I can't help you now. Provide a better schematic and I'll see what I can do for you.

Boncuk

the circuit the component list and the sch file is attached please help me improving the circuit in making layout for me. the 8 pin IC is(IR2111) and the 7812 IC is the voltage regulator the 16 pin IC is TL494 and MOSFETS are IRF540 and some capacitor and resistors please help me making an accurate design. Everything is attached except the layout.

How do you make an accurate PCB design if the faulty schematic still exists?

I do not intend to correct the schematic a way to put the blame on me in case the circuit won't work!

Follow all nets from beginning to end and all pins supposed to be connected to the nets.

At a glance I discovered two serious errors: The drain of Q3 has the net name N$39 ending in the middle of nowhere. The drain of Q1 is connected to net N$40 which is supposedly N$39, leading to fuse F1. You should know if the nets have to be the same.

GND should supposedly be connected to the source of Q2, but the net name changes from GND to N$19 with no ground connection! FATAL ERROR!

GYST and I really do what I can. Searching for net mismatches and unconnected pins will take more time than you have left over for your presentation!

I suggest to redraw the entire schematic (omitting nets drawn through the symbol of a device) asap and give me a call via Skype as soon as you have finished the design.

Boncuk

P.S. My hourly rate is US$350 to track errors in a schematic design.

And please! Use a frame format fitting the schematic design without having to alter the frame. DIN-A4 (landscape) is more than generous, not DIN-A3!

Instead of trying to create a schematic layout it would have been better to send me detailed photos of the original design for reverse engineering.

can u help me drawing the schemetics on skype my id is (khushal_kkk) please help me shall be thankful because i am so in need of this and cant draw myself and no one is helping me and m out of my mind and cant understand what u r saying :-( pls give me skype id or add me so i could talk to u and solve the issue

@Boncuk :
the 3 files are attached the Schemetics + Original Circit + Component List ...

TL494 IC
IR2111 IC
7812 Volatage Regulator
IRF540 MOSFET

and some resistors and capacitors

some more idea from the pic

Hi khushal,

since you're offline I post the PCB design here.

Perform "Ratsnest" before printing the board. This is important because of the ground fill.

I had to redraw the schematic as well.

Before you go to print the PCB layout compare your schematic with mine.

Regards

Boncuk

its now correct

no question about Boncuk's design.. Mr.kushal you can proceed with assembling

thank you for the help Boncuk and i am very pleased that there was some one who helped me alot and invested alot of time for me and i am very thnkful to you sir will never forget you in my prayers sir. God give u more and more happiness

Hi khushal,

I'm happy if I have made someone else happy.

I just hope that this little gesture of friendship will prevail throughout islamic and christian nations for a better mutual understanding.

Not that I'm afraid of war - I was a "cold warrior" for 23 years of my life until the Sowjet Union broke to pieces.

Allah or God or who ever may bless you.

Kindest regards

Boncuk

Thanks for the flowers.

Did you really compare the schematics?

Boncuk

Aftr all now i know u are a strong man because in mid i saw ur anger just like soldiers nd i love the way u treat humanity , may God bless u sir nd offcorse this will help alot in bringing some muslims nd cristians nearer nd nearer atleast me nd yes sir i did checked the schemetics its exactly the same ive gven in jpeg format .

sir can u go through the circuit diagram please there is a little mistake in that the DC jack i need is attached , and the diodes connected to dc jack are connected to one pin instead of goin to seperate pins
2) the pads GNDA is with A and GNDB is with B because there connects the 2p Termianls.

i dont know how to fix sir please can u do that for me
