I think there are several answers: 1)Design Fail - slap whoever created it 2)Fit that connector as a manual process after the PCB is finished. 3)Print side 2 using a jet printer 4) Shield the fragile LGA and reflow it twice anyway. 5)Use a thicker PC

We have an issue with solder wicking up the leads/ inside terminations on an SMT connector. The solder coverage is sometimes over 50% of the connectors inside pin length. The terminations are gold plated. Is there an IPC spec for acceptability? Plea

Sounds like you could have a problem caused by the gold. How thick is the plating? Are the connector leads gold too? I have seen gold cause dry looking brittle solder joints in the past.

We have a PCB with the dual sided connector that slides on from the edge and has leads on the top and bottom sides of the PCB. It has 20 leads on each side of the PCB with with about .8mm pitch. The PCB also has a gold grounding strip on the edge fo

It could be a gold finish problem. The recommened gold finish thickness is less than five micro inches. Gold thickness greater than five microi inches is significant contributor for causing embrittlement of the solder joints. Verify the reflow profil

http://suddendocs.samtec.com/literature/em_tectalk8a_lr.pdf Even so its still a fairly manual process so I guess you really have to want to use this type of connector because its a whole process in itself and I bet the whole family is a special or

I've always assembled those style connectors by hand. They require paste on both sides, correct? With that variable, I've never considered trying to do them with paste/reflow. Cheers, ..rob

Hello Dears, I'm a small CS Engineering at Taiwan.There are some problem on DIMM connector area with poor solderability at ODM. It was random on Dimm connector area and the SMT area is fine. At the same time, there were other PCB vendor's product whi

Hi, I'm looking for vendors that manufacture connector pins that would solder onto the edge of a small SMD pcb so that I can mount it as a SIP onto a larger PCB. Better yet, are there small diameter pins that can be soldered into thru-holes so the SM
