This repeats a very similar thread recently. The obvious answers are given already. However there are extra/different steps that can be taken depending on where your data has come from. If you are an OEM and you are building using data that was gener

First, I don�t understand why your board fabricator can�t do a good job plugging your vias. Additionally, when you consider that they forgot to plug the first batch of boards, it makes me wonder if they are desirable as a supplier. Generally, we us

Dave, this is a massive question, and if you have any hard data on these issues, it would be wonderful if you could share it. The best I can offer is some indication of our experiences from contacts in the industry. Keep in mind as well, that we ha
