Solder placement nozzle assembly

A nozzle assembly of the type which includes a heated metal tip of a soldering iron for depositing solder onto a series of solder wettable contact pads of a surface mount circuit board, the nozzle assembly comprising:

• a nozzle mount supportable above the conductive surface to be soldered, the nozzle amount having a polygonally shaped upper exterior and a generally cylindrically shaped lower exterior which together define an overall length, the nozzle mount also having an internal bore sized to receive the heated metal tip of the soldering iron;
• a nozzle head having an upper, generally cylindrical interior bore which joins a lower, converging interior bore, provided with a solder feed orifice, the upper, generally cylindrical interior bore being selectively sized to receive the lower exterior of the nozzle mount, thereby allowing the heated metal tip of the soldering iron to extend at least partly within the lower converging interior bore of the nozzle head for contacting solid solder fed within the lower, converging interior bore through the solder feed orifice;
• mounting means for removably mounting the nozzle head onto the nozzle mount;
• wherein the lower, converging interior bore of the nozzle head terminates in a solder reservoir for molten solder which is fed within the lower, converging interior bore to contact the heated metal tip of the soldering iron and wherein the nozzle mount and nozzle head are formed of a non-wettable, plastic material.
