Pricing my first PCB Layout contract

[Sij]

James:

Thanks for responding. About 310 pins with approximate dimensions: 3 x 15 inches.

Sam




Not enough information.

Tell me the following, and I will give you what _I_ would estimate in time.

1) Number of 'pins'

2) Size of PCB - X & Y

That should be all I need.

I'm generating some gerber files for them using Orcad Layout, for a
board that is going to be used for testing various signal switching
ICs. I believe they have 9 or 10 different ones.

There will be a DC power jack mounted for 13V as well as a regulator to
generate a 5V supply.

Each IC to be tested will need capacitors; 2 per input and 2 per
output per chip; a total of 4 per chip, about 40 in all.

Each input/output will be connected to an RCA jack; 40 RCA jacks in
all.

and of course each chip needs to be grounded.

For EMI shielding, I think minimizing loop area, bypass capacitors and
employing wide tracks for power and ground should be sufficient.

As far as the jacks go. I will have to create new symbols and
footprints for the RCA jacks, the power jack and perhaps 5 or 6 of the
ICs so that it is layed out properly on the PCB.

I've agreed to an hourly charge of 20$/ hour.

How much time would you charge for a contract like this? I'm new to
Orcad layout, but I'm learning it quick. I won't charge my time for
research and learning how to use the program because I'm junior.
However, I do seek a price that is worth my while. I'm also hoping that
this opportunity will lead to full-time employment. Either way it
looks good on a resume.

Cheers,

Sam

Sam,

Without spending too much time looking at this... my calculator tells me
that it would be a 37 Hour job.

This would include everything from start - to deliverable Gerber files -
including all of the associated drawings, etc.

You may be able to get it done in less time - but it certainly should not be
over this.

Good Luck.

Regards,
