Has anybody else out there had problems with SMT connectors with plastic locating pins lifting up during the reflow process? We've had several instances with several differant types of SMT connectors lifting up during the reflow process. We've even g

I'll ask you the same questions as this poster ... http://www.smtnet.com/Forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=4627&mc=2

My first thought is board warp. This is something you can't see when the board is in a reflow oven. I see it occasionally going through wave solder. You may need a pallet with hold down clamps for reflow. Try putting a bare board in a baking oven at

Hello ! Please offer some clever solution for the following problem 2 sided assembly. The side which must be assembled first has 2 SMD RJ45 connectors. They have plastic location pins. Which protrude tru the board, about 0.4mm So, when I want to a

Yes, thats the most obvious solution :) But its a quite specific and densely packed socket, so my hopes are not that high :)

Why would you assemble first side with TH component? Can't you start from the second side?

The "clever" solution is to revisit the design. Move things, choose a connector with SMT tabs and no locating lugs. File this mistake away under "oops". You should also revisit the datasheets for your parts. Most components should be fine to reflow

I got very few components on the first side and all these are not heat sensitive. On the other side I got 5 times more components, including electrolytic caps and micromodules, which love the lower temp of LMPA pasta and also, they would enjoy more i

Why not use tooling pins (locating pins)? Sounds like the same accuracy...

If you could change the design, a 2x25 1.27mm pitch surface mount connector is a standard part from Wurth. Samtec also do versions in any pin count you might desire, with locating pins, without, with picking clip etc.
