Hi all,

We are experiencing problems with a 6-way surface mount connector. The part
in question is a Harwin part M22-634XX22R.
And to a lesser degree the mating part M22-C107133C. The problem is that the
joints do not appear wetted at all, the
component legs seem to be sitting on top of the solder and the slightest
force will cause the connector to fall off. The
problem is currently being investigated by our manufacturing department, but
I am keen to glean as much info as I can
as to the possible cause. As is the first time with have used a surface
mount connector, any advice would be most appreciated.

I have sent this message to the TechNet forum, but I would be interested to
hear from any pcb designers who have used the
above parts, or similar parts and have experienced problems. Especially if
you have had to make any changes to the recommended
footprint to meet your assembly requirements.

Best regards,

Mark.
