Actually we have them soldered by a contract manufacturer as we use them on
our development boards. The way they connect them is to use a larger
soldering iron and pre-heat the board.

They do get excellent results. I just had a customer unit back for FA where
the customer damaged the board, on one of the ground pads the connector had
broken in half in the horizontal pad plane. On the other side of the ground
connection it had ripped the pad from the board so I guess no issues with
their soldering method.......8-)

I just called the contract house on this and he reports that on my board the
ground is connected through a via to an inner layer so not too bad
thermally, he did comment that if it was connected to a top side ground
flood plane it might be a little more "interesting"

They use a higher activity flux and water wash.

Subject: [TN] How to solder this one

Dear Technos,

 

How do you guys solder connectors similar to this one?

 

 
http://www.molex.com/molex/products/datasheet.jsp?part=active/0731000114_RF_
COAX_CONNECTORS.xml&channel=Products&Lang=en-US

 

We have to take on a similar one, from Zargo, gold plated brass. On top of
it we need to do it RoHS.

 

Very hard to solder, even if I preheat the parts on a heating plate.

 

Thanks,
