altiumfootprintmosfet
Anyone know if the footprint wizard in Altium can be used to generate SOT669 package footprints?
It appears to me that its only capable of 3 lead MOSFETs. I searched the web and couldn't find anything, I don't mind making footprints by hand but its a standard form factor and I'm a little confused why its not an included option.
Someone feel free to correct me if I am missing something entirely within the options on Altium.
Download the STEP (.stp) model from the Molex web site. Unzip it somewhere sensible. Also open up the datasheet drawing.
Open up your footprint library. Do Tools->New Blank Component.
Since the component is specified in mm in the datasheet, switch to metric units. Press 'O' 'B' to bring up the board options. Switch to metric
Now to place the 3D model. Press 'P' 'B' (for Place Body). Click 'Generic STEP Model', then 'Embed STEP Model' and select the file. Set the X rotation to 90ยบ and the Standoff height to 2.9mm.
Click OK, and place the model on the document. Now drag the purple rectangle by the middle of its lower edge, and snap it to the origin.
Now to place the pads. According to the datasheet, the pads for the connector are 0.85mm x 7.00mm, and are placed 1.50mm apart.
Press 'P' 'P' (for Place Pad), then press 'Tab' to bring up the pad options.
Set the X and Y size of the pad, and make it rectangular. Set the Designator to 1, and the Layer to Top Layer. Click OK.
Now place the three pads on the document. Do the left one first (at -1.5, 3.0), then the middle one (at 0.0, 3.0), then the right one (at 1.5, 3.0). Right click to stop placing pads.
Now press '3' to go into 3D mode. and check that the pads look like they're placed correctly.
Go back into 2D mode '2' to place the silk screen. Switch to the Top Overlay layer, and press 'P' 'L' (for Place Line). Press 'Tab' to set the options, and set it to 0.2mm. Draw in some lines to give an indication of the part size. Don't draw them over the pads.
Now go to Tools->Component Properties. And fill in the properties.
Save the library and you're done.
Go to your board.
Select what you want to get. (Use Shift+S to set only the current layer visible and selectable)
Ctrl+C (and don't forget to mouse-click an origin after, or nothing gets copied - make it the new component origin if you like planning ahead like I do)
Go to the PCBLibrary (or make a new one)
Tools -> New Blank Component
Ctrl+V
Click where you want your pads.
Edit the component properties and 3D model as required.
Ctrl+S
Done.
For posterity, to quickly select a group of objects with same or similar properties, you can use:
Right-Click on object: Select "Find Similar Objects"
In the menu find the properties that are unique to the group of objects and select "same" from the dropdown.
Select Apply and then Ok and you get a listing for all the items matching your parameters, while they also become selected. (Technically usually only Ok works, but it may sometimes give the dreaded DLL based pop-up of doom, while preceding it with apply never gave me that).
To select on part of a parameter you can use an Asterisk (), like selecting all objects with a name that starts with JP, you can select "same" in "Name" and type "JP" and all JP1, JP101, JP2938, etc will become selected.

Altium seems entirely happy to generate DPAK-style footprints with arbitrary numbers of leads and arbitrary pitch:
You may have to override most of the default dimensions, but that should still be easier then doing it manually.
