Description

The most widely used type of pin, best suited to normal size & normal thickness die pick-up.
The rounded pin point allows for die pick-up and prevents the mounting tape from being pierced. This is helpful in preventing damage to the back-side of the die during the pick-up process.

Flat (Type 2)

Description

Best suited for thin die pick-up. The flat pin point prevents the die from cracking during ejection.

Bottle neck (Type 3)

Description

The narrow size of the pin point of the bottle neck design makes this type best suited for small die pick-up.
