design rule for assembly

a) Which rules we should obey in PCB design to make it auto-assembly-able?
b) in AD more that three type of footprints exist for 603 resistor, some with body keep out and other without it! which one we must use?
c) how many spaces do we need to preserve around each component for assembly tools?
d) Is there any special rule in component library generation which must be considered? Specially component origin?
e) Can we use any direction for component placement, or it must be along x-y direction?
f) regarding the press-fit connectors, how we can assemble an diss-assemble it?

a) There are no rules that guarantee easy manufacturing
b) They will all work. The best one is the IPC-7350 ones found in Altium Designer 6\Library\Pcb\IPC-7350 Series folder. You can also make your own using the IPC footprint wizard.
c) You need to ask your contract manufacturer. The IPC footprints do have an assembly courtyard layer which gives you an idea of how close you can place components to each other.
e) You can rotate components in any direction. Again I would ask your contract manufacturer what they prefer.
f) I don't know what you mean.

how we can inform the list of do-not-populate components to assemble? is the list extracted directly from schematics or it is manual job? also how about assembly variant?
 

You can just put in "do not populate" in the bill of material that you give to your contract manufacturer next to the parts you don't want populated.

Here is a video over at altiums website which shows how to do assembly variants. **broken link removed**

Does assembly variant information transferes to Pick-and Place file? or Pick-and Place file does not change and it must be done seperately?
 

If you use "Outjob" to generate your files, you can select the variant to use when generating pick and place files. See page 25 in the following document found in the "Help" subdirectory of your installation "AP0128 Managing Design Variation with Variants.pdf".

Is bom and pick & place file enough for assembly or other information needed?
 

Typically for the contract manufacturer the BOM, Pick and Place files, and solderpaste gerbers (for stencils). However you can also just give them the full gerbers just in case.
