Range: Loop Base 0 ~ 5 Setting : 2 ) Ball Offset This setting controls the distance of the table move in order to offset the capillary from the standoff ball. Negative value can be moved towards to the first bond. Positive value can be moved away from the first bond. Range: Ball Offset 40 ~ 20 Setting : ve 35 ASM ASM Technology Singapore 2 Yishun Avenue 7, Singapore 768924.
