The purpose of an SMT stencil is to transfer solder paste to a bare circuit board. Before the assembly of the SMT components solder paste is printed onto the component pads of the printed circuit board by stencil, which are today usually manufactured from steel, more rarely from nickel or polyimide.

I have a question regarding post cured property of SMT adhesive.
If after component placement, the epoxy dot gets compressed and bridges between the 2 pads, what would the impact on the circuitry? Would it pose risk for flux entrapment? Could the cured epoxy introduce any impedance to the circuit and lead to test failure?
