Hi All, With a product base consisting of large volumes of low technology products, there is always pressure for lower cost ways to do things. Recently, die punching has been brought up as a means of lowering the cost of these types of products. I remember die punching from the "old days" and am not overly thrilled with those memories, however, I can't seem to remember why die punching lost out to NC drilling & routing over time. I'm talking about punching Fr4 with PTH, not XXXP, or CEM-X based NPTH products. Is there a resurgence in die punching or is what I'm hearing about potential cost reduction all a bunch of hogwash? Where does one find information about die punching PWBs nowadays?
