Most any shop can install filled via in pad technology. It is, however, a
difficult process and requires some technical expertise and equipment. If
you do not have a steady stream of this product it is difficult to both
justify the cost and maintain an efficient technology. Consequently, it has
become a specialty item.

Best regards
