Thanks a lot,, so assuming we are using standard parts, with nothing out of the ordinary we could safely assume that a machine capable of 20 mil would be more than able to meet our needs down the road. | We are changing from through-hole to SMT, won

| hi everybody, | We've been doing some studies on assembly of CSPs. We assembled these packages on micrivia-in-pad patterns. These are 15/13.5/11 mil pads with 6 mil design microvia, using photo/laser/plasma tech. We are seeing voids, as big as the
