Hi Eric!

I think you can probably guess the problems that you will see. The
solderpaste will be smeared off the pads that may result in insufficient
solder defects and/or bridges. It is a very operator dependant process
that is inconsistent. But there is another way...

Have you ever looked into the straddle mount connectors from TEKA? They
have connectors that have what they call; "Solder Flux Bearing
Technology", which is a solid solder deposit fixed to each lead. The
connector slides on the board without worrying about smearing solder
paste...makes things much, much easier. Check out:

I've used both their SMT and PTH connectors (PC104 connectors) with
their Solder Flux Bearing Technology and they both work great!

Subject: [TN] Straddle mount connector

Hi all,
1.	What is the best process to assemble a straddle mount (edge
mount) connector on the SMT line? Right now, the only way we see is to
place it manually right after the printer.
2.	What are the defects and problems related to the straddle mount
connector assembly? 

Regards,
