The
stream of KerfAid treated deionized (DI) water delivered to the dicing
operation reduces thermal stress, die edge damage and internal cracking,
assuring long-term integrity of the devices being processed. Since KerfAid
is a coolant and lubricant, both the dicing blade and the device benefit.
As a coolant, KerfAid reduces heat caused by friction. As a lubricant,
KerfAid lowers friction and surface tension, which increases swarf dispersion.
-
Reduces
Surface Tension
by 25-40 dynes/cm2. KerfAid allows more water into the kerf, dissipating
heat generated by friction.
-
Bonds
Water Molecules into the kerf and to the dicing blade, allowing
better swarf dispersion and lubrication.
-
Prevents
Swarf Accumulation
on the dicing blade and in streets, minimizing chipping and internal
cracking.
-
Extends
Blade Life
by up to 30%. The lubricated blade runs cooler, reducing metal fatigue
and blade wear.
-
Improves
Die Yield and Reliability from the reduced amount of chipping,
cracking and consequent edge damage.
-
Eliminates
Scrubbing after dicing.
