Dome Coating effectively prevents chip and wire detachment, damage, and moisture ingress.
It is mainly applied for the protection of multiple chips and wires on leadframes. Typically, dispensing is done on the front side of the leadframe, with adhesive flowing through the gaps between leadframes to the back side. This results in a certain thickness of adhesive on both sides, protecting the chips and wires and increasing the lifespan of components.
The purpose of Dome Coating dispensing process is to increase the reliability of components, prevent detachment, collision, and damage during component encapsulation, primarily applied in the semiconductor industry for leadframe, chips, and wire bonding dispensing processes.
In the Dome Coating dispensing process, control over adhesive volume, adhesive height, dispensing trajectory, and dispensing range are crucial process parameters to ensure effective dispensing. In the Dome Coating process, adhesive height and consistency are particularly important.
The high integration of chips leads to reduced dispensing space, and compact packaging spaces. Therefore, controlling smaller single points and ensuring the stability of adhesive dispensing are industry trends.
