A solder jet apparatus is disclosed The solder jet apparatus is a continuous mode solder jet that includes a blanking system and raster scan system. The use of the raster scan and blanking systems allows for a continuous stream of solder to be placed anywhere on the surface in any desired X-Y plane.
A solder jet apparatus is disclosed The solder jet apparatus is a continuous mode solder jet that includes a blanking system and raster scan system. The use of the raster scan and blanking systems allows for a continuous stream of solder to be placed anywhere on the surface in any desired X-Y plane. This allows for greater accuracy as well as greater product throughput. Additionally, with the raster scan system, repairs to existing soldered surfaces can be quickly and easily performed using a map of the defects for directing the solder to the defects.

The method according to claim 1, wherein producing a continuous stream of liquid metal droplets further comprises:heating a metal to a liquid state;controlling a temperature of the metal in the liquid state to maintain the metal in the liquid state. 3. The method according to claim 1, wherein producing a continuous stream of liquid metal droplets further comprises:providing a source of a liquid metal;inducing a pressure on the source of liquid metal; andvibrating the liquid metal to cause the liquid metal droplets to be formed as the pressure is induced on the source of liquid metal. 4. The method according to claim 3, wherein inducing a pressure comprises operating a piezoelectric crystal driven at a frequency to produce a desired pressure on the liquid metal. 5. The method according to claim 3, wherein vibrating comprises operating a piezoelectric crystal driven at a selected frequency producing a vibration frequency to form micron size droplets. 6. The method according to claim 1, wherein producing a continuous stream of the liquid metal droplets further comprises forming the liquid metal droplets in a consistent micron size range. 7.
