Solder Ball Placement System / Ball Mounter STM-II

Back to Product List

Table-top Single Solder Ball Placement System model STM-II is available for prototyping, R&D, and repair(re-balling) of BGA type IC packages and substrates.


Solder ball placement can be made with unique solder ball separation unit which is simply interchangable.
The system has built-in flux Dispenser with flux temperature controller which enable to apply consistent volume of flux on each ball pads of BGA according to the placement pattern being set beforehand.
The machine operation with color wide touch screen enable to simply set various kind of BGA ball placement pattern and parameters.
