Pad Dilema

Biff schrieb:

I want to place four pads on a board and connect one wire to each pad.

 

I want the four pads to be tied together on top and bottom layers with

either polygons or rectangles or something else.

 

I want the area on the finished board to appear as one big pad with four

through-holes in it. Bare copper with no mask over the area.

 

Each hole will have a wire attached and soldered in the final assembly and

all wires carry the same signal..

 

Should I use polygons or rectangles or something else to make this.

Polygons will serve this purpose best (in the board, not in a library!).

Don't forget to also draw the stop masks (for those, rectangles will do).

Thanks Tilman,

Here is the complete drawing on the board (see attached GIF).

I have the 4 pads that accept one wire each. The other 2 pads are connected

to one relay contact. The relay contact has 2 pins on it that's why there

are 2 pads.

I want all 6 pads connected together on the Top and Bottom layers.

I have Polygons around all 6 pads on Top and Bottom layers.

I have a rectangle around the 6 pads in Tsop and Bstop layers.

Is this the correct way to do this? Do I need to set or apply anything else?

Many Thanks

The polygon needs to be named the same net as the pads to connect. Run

ratsnest to see the fill.

Also options such as isolate and width of polygon trace affect what you get.

...and no thermals in this case.

Thank you very much. Good advice from all.

I've got it laid out now and it looks good.

One thing I haven't figured out is how to connect a polygon to an "orphan

pad" of a library device that has been placed on the board. But that's a

whole nother can of worms.

...but answered quickly: it would represent a connection to a signal in

the board, so this signal must also be present in the schematic.

In EAGLE terminology, "orphan" pads must not be connected. Everything

that is connected needs a pin in the schematic symbol. (However, pins of

the symbol may be left unconnected.)

Thanks Much Tilmann. I really appreciate your input. Have an imaginary drink

on me  ;^)
