Model: MY700; Manufacturer: Mycronic

The MY700 high-speed jet dispensing platform for solder paste and a wide range of assembly fluids incorporates three highly productive machine models, each one with its own set of unique capabilities. A highly advanced motion system makes it possible to dispense fluids on-the-fly at 300 dots per second and with 3g acceleration as well as superior accuracy. Dot volume, size and shape are easy to adjust and optimise for each individual component and pad on the board.

The MY700 is equipped with a state-of-art vision system providing fiducial recognition on-the-fly and accurate laser height measurement to automatically compensate for board stretch and warpage, ensuring the quality of the final result. All this is in a compact package, accessible both at the front and rear with a footprint of no more than 1½ m².

Company sources claim that its non-contact nozzle that jets with high precision makes every solder paste deposit perfect, reducing the need for reworking and hence increasing overall throughput. Dispensing glue or other assembly fluids with the same machine, and in the same process step, saves space in the factory. The processes of encapsulation, and the selective coating of dots and lines with epoxy, glue or other assembly fluids are impressively fast.

Key features:

  • Dual heads for productivity
  • Dual lanes for smart board handling and buffering
  • High-speed high-accuracy dispensing
  • Solder paste and a wide range of assembly fluids can be used
  • Board revisions and changeovers can be done in no time
