I've got two PCB questions:
Does anyone make a PCB (or tool) that has various sized plated holes in it - for example, 20mil, 22mil, 24mil in a range of sizes from 2-70 or something like this.
Also, I'm thinking of trying some SMD stuff and I noticed many datasheets include a recommended layout showing where the pads should be, how big, etc. My question is - are these types of layouts optimized for automated soldering such as baking, etc? If I were going to solder a few by hand, should the pads be sized a little larger in a direction that doesn't matter to make soldering easier?
