SMT Custom connector soldering issue

SMT Custom connector soldering issue | 29 October, 2001

I have a custom connector that tends to lift during reflow. The PCB retention tabs and pins are lifting off of the pads on the board and the solder is forming underneath the pads, with no heel or toe filet. Is there anyone out there that can help if I email a picture of what is happening. I can be reached at Patcope1@aol.com or day time at pcopeland@novabio.com

I want to make a change to the connector but I am unsure of what to do. Any comments!

Sounds like the connector is not solderable. * Do they take solder when hand soldering? * Do they take solder when using a hotter flux than you normally use? * What flux are you using? * What are the materials used in fabricating these connector leads?
