Description

[Technical Field]

[0001] This utility model belongs to the field of dispensing head technology, and particularly relates to a die bonding dispensing head. [Background Technology]

[0002] Currently, the die bonding process in LED light source packaging mainly uses a single circular dispensing head to apply adhesive before placing the LED chip onto the adhesive. Existing needle-type integrated dispensing heads, such as the novel dispensing head disclosed in patent publication number CN206676653U, dispense adhesive through a single dispensing hole. This not only results in a small dispensing area and uneven dispensing, leading to poor dispensing performance, but also makes cleaning inconvenient due to its integrated design.
