We inherited a product line from a closed plant that lead formed a 
     .600 dip to gull wings using an arbor press. This is not a high 
     reliability process, mainly due to poor coplanarity. The DIP is then 
     hand located and either glued or reflowed. Hand placing is acceptable, 
     due to the extremely large lead spacing of a DIP.
     
     Use a surface mount socket if they must be reflowed, or even better, 
     purchase them with the proper lead configuration.

     Good Day TechNetters!
     
     What experience can you all share about forming through-hole 
     DIP packages into a surface mount configuration (J-leaded?) 
     so that the part(s) can be mounted and reflowed during the 
     SMD operation?
     
     Is there automatic equipment available to form the DIP 
     leads?  If so, who are the manufacturers and what would be a 
     ballpark cost?
     
     Has reliability testing been done to validate solder joint 
     integrity?
     
     Is anyone using pick & place equipment to automatically 
     place the newly formed part(s)?
