It will depend on how "advanced" your CM is. We are currently using Valor
and have had great success with developing tooling etc from CAD information.
Pending the amount of information in the CAD, package, polarity, footprint
attributes etc, we can generally use the customers CAD as a root for our
madness and then procede with little change to the information on the PCBA
level. But we would make modifications like poly shapes and placement
panelization etc on the info that is not usually done as a PCB designer, but
more as a Manf. Engineer.
ODB++ makes for a good format as well as GenCAD and GenCAM. Since we are on
the Valor side of things, ODB++ is our preferred. We do have translators
for different CAD outputs, so it just depends on what our customer has to
offer. Hopefully something better than blueprints....:^)+)

Subject: Standard Data Exchange Formats for SMT Placement
Hello All,
It's been awhile but I have a question for the contract manufacturers out
there. Understanding that each placement machine requires a data translator
(i.e. CIMbridge) to provide a friendly data format for ease of programming
and setup, but what is the preferred data format that you require from your
customers?
One other question: Is there a preferred industry accepted standard data
format?
The reason for my question is that we have multiple suppliers and are
attempting to get our CAD folks in tune with our CMs needs. Thanks in
advance for your inputs.
