PCB Footprint Altium Designer

07/01/2014 2:15 AM

Hi folks,

I am trying to draw a PCB footprint (surface mount version) for this relay and have a couple of questions hope you guys can help:

http://www.farnell.com/datasheets/1717896.pdf

What should the dimension of the pad to solder the chip on be? (I couldn't find it on the datasheet)

You have your PC drafting design department that has intellectual property on the design of component mounting, etching requirements, PWB manufacturing requirements design this foot print for you.

I guess you did not notice page three of your datasheet. The section titled "PCB layout".

As with any pcb layout the pads and tracks can have a minimum practical size but not a maximum unless capacitance issues are involved which is probably unlikely. Therefore make them as big as you can, saves on etching chemicals, makes pcb stronger, less chance of broken tracks, easier to alter with jumpers if there are any issues etc.
