Hello TechNetters: I have a question concerning pad design. Connector pad design/shape for through hole connectors. The connector is a 50 mil pitch connector. Question: "Is there an advantage to round vs square pad design if the connector is going to be wave soldered?" This is a High Rel Class 3 product (Military). What experience can you all share on this question. We will be soldering without the aid of a hot air knife. We have a Dover Soltec Delta Wave solder machine and are using Kester 973 VOC free Water Based No-clean flux being sprayed onto the board with convection preheating. You can reply over TechNet or direct. Ron Hollandsworth [log in to unmask]
