Help?

Are you sure you're using the right software for your particular desired workflow?

It doesn't sound like it.

EAGLE is all about schematics and then building a circuit board from there.

Schematics parts often don't use the same number of pins as a physical part.

If you just want to lay 'holes', then there may be other software out there that

you could be using - EAGLE would be extreme overkill for that -

although it could do it, you'd have to plough through the user documentation -

it's not intended to a MS Paint replacement and so the workflow isn't as simple

with EAGLE.

By the way, your part number M27C801-100B1 really is a 32-pin device,

not a 42-pin device.

I know the M27C801-100B1 is a 32 dip, however it is the chip I currently

use right now for my boards. I need to move up to the bigger chip which is

why I need the adapter board made. I only chose that from the library as it

was all there was and I knew the hole sizes and spacing was what I needed.

I was hoping I could just lay that chip out twice or something and over lap

the pins or just add the extra holes needed. I'm just going to call it a

day and pay somebody to do this. I really wanted to do it myself but I

can't waste all this time into this program.

As far as other programs, maybe but I'm pretty burnt out and annoyed right

now that I don't think I want to waste any more time learning another

program that may not be correct for what I need done.

Thanks for the reply. It's nice to get some input from someone.

It seems to me you've not made any effort to learn this one, nor to

learn the basic principles of the task this one is designed for. Now you

are fully at liberty to not want to put the effort in, but if you do

take that tack then you have a moral duty to accept the blame yourself

and NOT BLAME THE TOOL. It's a perfectly good tool, you just don't want

to use it right. Like the blunt edge of the pizza knife, or the

screwdriver as a hammer.

The work flow in electronics design IS ALWAYS to start with a schematic,

select components with appropriate packages, create library parts as

required, and only then start to worry about layout. THIS DOES STILL

APPLY in the trivial case you have, regardless of whether you think "oh

it's just..." - because even that statement is a description of the

schematic you should start by drawing. Or rather, the statement is a

vague, hand-wavy marketing overview of the requirement. You really need

to formalise that requirement by drawing a schematic. Only then can you

consider how to implement it on a PCB.

If you give up on your preconception that "it's too trivial" and admit

that for a proper job you need to be precise in your requirements, then

you'll find that Eagle does help a lot. Sure, it's a non-trivial

learning curve, but then all such tools are.

Well it has pads on both sides. I used a "header pin" layout remember.

Trust me I barely understand what I did. I just dropped the library file

and sent it out. I actually got some boards in today. I only ordered 10 to

make sure they will work.

I need the 1/4" hole as the case it goes into has a 3/16" peg that pushes

against the main pcb that this will be sitting atop of.

The only thing I did not do that I have heard mixed feelings about is

ground the unused pins. I guess I could do that before I order the bulk of

the load, but I made a test board and ran like 35 wires by hand and just

bent up the pins to nothing and it works fine, that was months ago I did

that and it still works fine?

Except for the mounting hole, you need PADS not holes. A pad is a hole with

copper around it. You cannot connect copper traces to holes. You can only

connect traces to pads. According the the drill symbols, your mounting hole

is actually the same diameter as the drill for the pads. To make it 1/4",

click on "i", then click on the hole. In the dialog box you can edit the

drill size of the hole. BTW, 1/4" is HUGE. You will then have to re-route

your board. First, you need to rip-up the traces. Type "RIP *" (without the

quotes) into the command line. Then route the board.

I see that there are several pins that aren't connected to anything. All

CMOS inputs *MUST* be connected to either +V via a resistor (i.e. 10K) or

directly to ground. CMOS inputs will act erratically (bounce between '0'

and '1') if left floating (unconnected), and your board will act

erratically, too. Floating inputs also draw more power. You may be able to

get away with leaving them float, but then you will have failures in the

field.

I sure do hope this is correct. I just ran connections all in schematic. I

went into net classes and made width .5mm, drill 1mm, and clearance .5mm I

then ran auto router and this is end result?

I have that hole on bottom that is suppose to be 1/4" but it doesn't look

like a 1/4" hole in the green pic. I had only shown layers, pads, holes,

drills, and vias.
