I have been awarded a contract to do board layout for a circuit that
will test the noise, cross-talk and bandwidth of various analog and
digital switching ICs.
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 blocking DC on 2 inputs and
2 outputs 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 will be minimizing loop areas and using wide
traces. The designer hopes to achieve 100MHz bandpass.
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 working
a 8-5 job as well so my time on weekeends is limited.
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. Creating
the symbols/footprints will take a while. Also, I hope to receive and
offer for full-time employment with this company after the contract.
Either way its good experience for the resume.
Thanks,
Sam
