Epoxy Dispensing Nozzle
Perfomance is COST
We give you BOTH
In die bonding, epoxy deposition onto the substrate prior to die placement is very critical and challenging especailly when it is prone to "delamination" resulting in the product reliability or even failure.

Poor or incomplete epoxy dispensing with voids will create trapped gases during curing between the substrate and benealth the die. It should be avoided.

Other design consideration include the controlling the amount of epoxy deposition limit the fillet height of less 50% of die thickness.
