Hi gEDA gurus,
3. In my next PCB, I need to add surface mount components. I've noticed that some part data sheets spec out the pad sizes, but many don't--they just spec out the part feet. Are there good general rules for making SMT pads? Generally, what should the space be *between* the pads?
I've been able to find manufacturer's footprint recommendations for all of the SMT parts that I have used.
