Hi,

 Guide posts are about all I can think of for hand placement. If you can
grab it by the machine then post less connectors could be placed.

 This is the kind of thing that design folks should consider up front.

 Skilled operators with steady hands?

Subject: [TN] Straddle mount connector at SMT

Hello Technet,

I would like to ask for input on processing edge mount (straddle mount) 
connector at SMT,

1.	What is the best process to assemble a straddle mount (edge
mount) connector on the SMT line? Since the connector has to be installed 
manually prior to reflow, how can I avoid paste smearing between the 
connector leads and the SMT pad? The particular connector manufacturer in 
my case recommendeded a partial solder paste deposition on the pad and rely 
on solder wicking to complete a solder fillet. How reliable would such
process 
be?

2.	What are the defects and problems related to the straddle mount
connector assembly? 

Any feedback is appreciated. 

Peter
