How to create pad for SMD parts

HoRangHam

Hello,

I'm really new to the OrCAD layout and know nothing about this before. I'm sorry if there is any dump questions from me :)

I'm try to create a foot print for this part.

 

1. First question is: As I understand that to create this footprint I first need to create the 0.40 x 1.22mm pad right? 

To create the pad I learn that I need to used Pad Designer. I also have have couple questions about this as well.

 

2. What informations I need to enter in the box 1, 2, and 3? What do they mean? Is there any book teaching about this? I would like to buy one to read. Or any guide that show how to make a simple SMD pad.

 

3. For SMD pad, I just need a Single layer mode???

Please help a newbie out. Appreciate for your help.

    You are actually using Pad Designer from OrCAD PCB Editor. The document to look in is algrolibdev.pdf in the doc\algrolibdev directory of the installation, in general and specifically the Library Padstacks section for padstacks. For an SMD pad, set the Single Layer Mode in the Layers tab and define the "Top" details, as required, just the Regular Pad parameters will suffice for most applications, you don't need to worry about the other settings you indicated since these relate to drills and through pin parts. And, yes, you do need to define the pads / pastacks first before moving on to design the symbol.
