     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.
