Screaming Circuits: Via in Pad Category

Via in Pad Category

Via in pad seems to be one of the hot topics these days. It's a real tough one too. The manufacturing guys pretty much always just say: "don't ever do it." However, with certain parts, the component manufacturer strongly recommends it. You gotta love those mutually exclusive requirements.

Rather than just telling you "no, never", I'm going to do my best to give guidelines on how to do it properly. With so many variables and options, this will take a series of posts covering the subject. I've created a new category, "Via in pad" so you can easily get to everything I've written and will write on the subject.

Check back. Over the next few days I'll cover the various methods for properly dealing with pad vias so that you and we can ensure a reliable board assembly.
