If the pads are the same size, shape and position on both sides you can do this in a text editor by copying the pads, and pasting twice. You then change the flags for the second set of pads for the second side. You can either increment the pad numbers as well, if the connector is bifurcated.

I'd use the PCB GUI: 1) Set the grid to a multiple of the distance of the fingers. 2) Draw track segment with appropriate width on the first layer 3) copy-paste to yield a row of tracks 4) copy the whole row to buffer 5) paste the row somewhere. 6) select the second layer 7) do [m] on all segments of the second row to move them to the second layer 8) move the second row to the same place as the first row 9) Go over all segments with [n] and enter the correct pad number 10) draw the silk 11) copy everything to paste buffer 12) do convert_to_element 13) paste the component somewhere 14) go over all pads with [q] to make them square 15) save 16) run my convenience script set_pinnumber.awk to set the pin numbers to the same value as the pin names. 17) copy component to buffer 18) save_buffer_as from the buffer menu 19) upload to gedasymbols.org Sounds like a lot of work.

Just chop off pieces of flat copper wire like is used in track light channels and motor and transformer windings and use mini spade terminals and very ordinary crimpers to put them on wire. Most contract manufacturers would already have a wire end stripper and a wire end crimper for such old fashioned parts. The novel idea is to put the "spade", (1.2 cm clipped from a roll of wire), at a notch in the edge of the board to protect it from bending/shorting. A rectangular hole milled in the board away from the edge would work too. If this happen to really be novel, I now license it to all of you as TAPR.org lic. open hardware. The mini spade wire terminal half is old old expired patent public domain now.

Re: gEDA-user: OT: High Temperature Connector
Thanks to everyone for the suggestions. The Phoenix style are a bit too tall. The Omnetics are too expensive but the Omnetics site did mention the materials that the 125degC and 200degC rated were made of so I was able to find parts at Tyco and Molex with the high temp materials. I had originally specified the Zierick 1245 IDC. Mfg is requesting a tool-less option at final assembly so we started to look at different options. The majority of the low cost connectors have 85degC or 105degC operating ratings. The AVX looks similar to the Zierick (as far as function and installation). The Zierick is probably less expensive. I will search the AVX site for other options. I did not see operating temperature ranges for the Zierick so I have a call into the Zierick salesman. Thanks again for the suggestions.
