     Jim,
             We have been successful at intrusive soldering PIH connectors 
     on the back side of SMT assemblies. We made the openings in the 
     stencil as large as possible, larger than the pads, and increased our 
     stencil thickness in that area to give us enough solder paste for an 
     acceptable joint.
     
     
     Good luck.

-- [ From: Jim Zanolli * EMC.Ver #2.10P ] --
     
Does anyone have any ideas on how to solder thru-hole connectors 
without the extra step of wave soldering? In many cases a sufficient 
volume of solder cannot be achieved by applying solder paste to the 
hole. 
     
In another case the connector has long .485" .025 square tails that 
must have  gold plating to allow mating to another connector after 
soldered to PCB -- and therefore cannot even be wave soldered. Are 
there any alternatives to laborious hand soldering or solder donuts?
     
Does the term "intrusive reflow" define the soldering of thru-hole 
leads by paste in the hole and reflow?
