ARES IC Package Problem :(

[areebahmed08]

HI
Im From Pakistan . Im an student of B.E Electronics from NED University .
My teacher gave me the task of making Circuit. Most of the student doing in bread board or vero board but i want to make PCB USING ARES 7
. Im suffering from just one problme i.e. Package of IC
I have to use Intel 8085A Microprocessor but in ARES there is no such package , so now took alternate other 40Pins IC. But im worried about size of the IC (( Similarly same tension for rest of the 3 IC (((
If it wont match the size of the actual IC than how can i sold pcb using my IC (( Plz help me

The packages and dimensions are described in the datsheet https://pdf1.alldatasheet.com/datasheet-pdf/view/122712/INTEL/8085A.html

Which one are you using?

 

[areebahmed08]

My Teacher didnt tell me about that , Im a student of 3rd year(5th semister) dont knw much about Microprocessor, but i can tell you all the details mention in my IC which shop keeper gave me :
P8085 AH
L6120078
i '76 '80
Thank you so much for quick response sir

Sir How can identify which package m i using ????
Is there any way to find it ??

Sir its 8-Bit HMOS Microprocessor

Usually there is a guide in the datsheet that describes how to read the letters on the chip but I can hardly find a datasheet for it and the one I found has only the footprint of military versions so I have no idea which case you have.

Do you have it in your hands, can you measure the width and length of the chip?

 

[areebahmed08]

Yes it is in my hand .... Im looking to it in a strange manner
by the way in mm ??

Whatever you prefer, I can convert it later

Does it match ?

If it does the DIL40 foorprint of ARES matches it

 

[areebahmed08]

Yessss Exactly this one i have )))))
I measured it by ruler just now. Exactly the same package

 

[alexan_e]

Use DIL40 and enjoy

If you want print the board on a paper using the printer when you finish the board and place the chips you have on the paper where they are supposed to be place to check if the footprints are match, if they do then proceed with the PCB development

 

[areebahmed08]

Thank you so much Sir )))))

I have taken printout and it fits well i.e. the footprints.. Thank you soo soo much Sir

Check this out

Seems a nice board, just watch the track I show below that has a very thin width.



You can move the track it a little to the right and then increase the width, if you leave it thin like this it can cause problems

Also make sure you have decoupling capacitors (100nF) close to IC supplies
