Hi If you mean your PCB stayed in the Reflow oven more than the reflow time required for the solder paste specs then I suggest to throw away the board because it would lead over heated solder joints all over the board. Think what could happen to an

Solder mask requirements: * IPC-6012 and IPC-SM-840 contain detailed specifications and information regarding solder mask requirements. * IPC-A-600 defines acceptability of printed boards [analog of A-610 for board assemblies]. Why can't you use A-6

I have to correct something from my previous post (before someone else corrects me). You can grow dendrites from any conductive surface (Cu, Ni etc.) but the final stage would be lower SIR. In my experience other metals except for tin do not lead to

Have you tried higher peaktemp? I saw the QFP is sn90pb10, This has a liquidus of 268 - 302 C. A good paste should be able to handle 230C (or more), of course you would need to check your other components peak temp.
