Negative
EFO
Reduction
of cratering, better grain formation, and longer capillary life are just
some of the benefits attributed to Uthe's Negative EFO unit. With closed
loop current feedback and voltage feedback versions available, Uthe's
Negative EFO provide precise and consistent ball size control. |

Negative
EFO Torches
Used
with ball bonders, the EFO torch acts as the cathode of a negative EFO
system. Discharges ranging from 1500 to 6000 volts (depending on the EFO
model). Carbon build up on the tool, increases the deterioration rate of the
EFO torch which in turn lead to inconsistent ball formation. |
