Hey guys so im nearly done designing of my project and the final steps is to put in pads for the SMA connector.

I cant seem to work out the pad sizes from the below data sheets.
Ive searched online for more information and couldn't find anything so i assume there`s something im not seeing in the below data sheets.

at the moment im assuming the pad width is to be 0.42 mm as shown in drawing sheet, is this correct ? and also what would the length be?

Thanks in advance folks !

Presumably, you are using a program to draw your schematic and PCB. What program are you using?

If you have access to the free version of EAGLE files, look in library "con-coax > SMA" and you will find something like this (they are fairly standard):

If you want to draw yourself, find a different datasheet that shows the dimensions that you need. Remember they are usually designed for double-sided boards; although, you can use just the top pads for a single sided board.
