headers skewing on alluminum board | 1 May, 2015

Good afternoon, We are running some aluminum boards through a 7 zone reflow oven which have 2 4 pin right angled headers on the ends that are skewing. Does anyone have any suggestions to prevent this from happening?

They are probably getting a little hot. So that leaves several courses of action.

1: Don't place them before reflow and hand finish. 2: Shield them with a little folded shield to decrease heat transfer. 3: Speed up the time through the oven, but this may cause other problems.
