UTHE 228-1

Uthe Negative Electric Flame-Off Wire Bonding Modules

Features

    Reduces Deterioration of Bond Capillary

    Better Grain Formation

    Automatic Time Control

    Retrofittable for Gold and Copper Applications

Unlike most EFO, Model 228-1 incorporates a close-loop circuitry
that will automatically adjust the time of current flow during
ball-formation to compensate for varying conditions caused by
inconsistent tail length, etc.

Description

The Uthe 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.
