Clean up!, check all conveyors for paste, the printer, oven. If you are splattering in the oven than you need a better profile or better paste, one of the two, maybe both. Hope was helpful Russ

How does your profile fit the paste manufacturer's specs? It sounds like you could be ramping up a little fast and boiling your non-metal constituents.

Actually we run lead free solder paste and the profile spec very tigh.I can't use capton tape due my product in panel form and save cost.I already verify conveyor,machine and tool free from dust and solder paste but the problem still remain.

If you are using SMT machine for component placement you may check your nozzle where in some cases solder paste stuck to it and during placement will easily get into gold pad area. otherwise you have use kapton tape in order not to expose those pads.
