Patent ID: 7066378

Claim:
A filling system for filling vias in an electronic substrate, said filling system comprising: a source of pressurized fill material; a pressure head with a pressure chamber, a plurality of fill material inlets, and an elongated fill material outlet, coupled to the source of pressurized fill material by the fill material inlets, whereby fill material flows between the pressure chamber and the source of pressurized fill material, and between the pressure chamber and an electronic substrate; the fill material inlets being orifices through which fill material flows when flowing between the source of pressurized fill material end the pressure chamber; the fill material outlet being an orifice through which fill material flows when flowing between the pressure chamber and the electronic substrate to be filled; the fill material outlet being at least X times larger than all of the fill material inlets combined where X is one of 3, 5, 10, and 20; and a dispersing mechanism for dispersing fill material flowing into the pressure chamber from the plurality of inlets along the length of the fill material outlet.
