So lets say that in a project i have to assembly versions called V1 V2 V3
and due to space and some other electrical reasons i need to have overlapping components as in :
case1:
V1 has a relay while V2 has a resistor shorting the relay but i dont have space on the bottom side so the resistor pads have to be on the same layer as the replay so the 3D models and courtyards intersect how do i do this properly? since i can simply ignore the rules and tons of DRC errors but i am sort of sure there is a better way ( since they will never be both placed at the same time

case2:
V2 uses a SOIC14 ADC/AFE while the V1/V3 uses a SOIC16 ADC ( yea i can use the large one for both but i would rather not, i did not get a quote on the larger combined amount but i am preparing for the worst ) yea i can change from versions the IC name/ manufacturer code BUT how do i make sure both will have the correct placement position ( they are entered/aligned to pin 1 (side with a notch above) asking since the footprints are often centred in the centre but that would mess up the alignment ( maybe with a custom* SOIC14 footprint that is centre offset?

For case 1:
Put both the relay and resistor in a special component class. Create a rule for component clearance for component of that (earlier) class to allow overlap (0mm).

For case 2:
I do not know exactly how you want to or even can do this. Rarely would a 14 pins device be pin compatible with a 16 pins device. If we assume pin compatibility...
- For alternative part: you would need to place the 16 pin device on the PCB and have documentation on how to place the 14 pin device on the same spot (pin 1 to 1 or pin 1 to 2).
- For two schematic parts (fit/do not fit): place the 2 footprints so that the connections match. This too would require documentation.

If the parts are not pin compatible, it is often better to place them apart and not overlap.

it has chiplets inside that is why it is compatible

Sniper2 , 04-20-2024, 03:51 PM

one has 2 chiplets + controll the other has 3 + controll

is there a place where i can find all Altium programing paramet4ers?

QDrives , 04-21-2024, 09:48 PM

"Altium programing parameters"? Do you mean for the Delphi/Pascal scripting language or something to make queries (ie. for rules and selection)?

Second

I would start here: https://www.altium.com/documentation/altium-designer/working-with-the-query-language
And do not forget the "Find similar objects" function.
