Hi,
I need footprints for all the general componants like through-hole resistors for 1/4W, 1/2W, 1W and 5W and capacitors 10UF, 100UF, 1000UF Radial Lead and DIP package IC's and general commonly used audio amplifier IC's like TDA 2030. Can someone please share these footprints? It will be very much helpful to me and many other people I feel. Thanking all of you in advance. |

Hello - What is the recommended symbol origin for connectors? I've been using pin 1 for both SMT and PTH. Our engineers would prefer body center for the SMT but some of our connectors are difficult to determine where the body center is located. I've included an example. |

Pin 1 is the most common 1st. In the middle of a single row is 2nd. In the component body center is 3rd. The new "Package Designer" coming out this weekend in V2013 allows you to create the above footprint in a snap and you can relocate the origin anywhere you like. |

If it's a surface-mount connector then I'll always put the footprint origin in the centre-of-body. If it's a through-hole connector then I look at the connector type and what it's going to be connected to. If it's going to be a board-to-board connector then usually I will go for the centre-of-body since it makes things more straight forward when positioning opposing connectors on different boards. If it's a screw terminal or wire-to-board connector then I will go for pin 1. I find it useful sometimes when I put the origin on pin 1 to also put a marker on the "placement layer" (or what a PADS user would call layer 20) for the centre-of-body of the component as well - but make it visibly different from the normal component origin marker - to give me something to pick up on "snap" and place at a specific position. Since I work on a metric grid it helps with components with connections on a 2.54mm pitch, on those "grey-area" components that may end up being board-to-board in some cases. |
