A little late to the party here, sorry... Has the joint been verified as a cold solder joint? That is, visually confirmed that it looks like cold solder, and, perhaps, xrayed to confirm the solder status? X-raying may sound a bit extreme, but you'

The major problems are poor layer to layer bond strength(due to surface tension of most fluoropolymers),and poor cold flow,or dimensional creep of these materials.Please also click on Chapter Author Konsowski,listed above.E-mail form will pop up when

1.Vias near SMD pads: Solder can flow into the via after melted. As a result cold joint will appear in the end. Check the picture below. 2.Vias on SMD pads: Solder can flow into the via more easier after melted. Check the picture below. 3.Via opening without soldermask covered. When workers solder TH parts by hand, soldering iron can touch vias sometime, then tiny amounts molten solder will stay on vias. This can lead to electrical short easily. We recommend you make all vias tenting (covered by solder mask) if it is possible.
