New range of flip chip adhesives

According to the different process and product requirements of the project partners concerning the curing conditions, the thermo-mechanical performance and the interconnection mechanism, Heraeus developed three systems for flip chip bonding in the range NCA (non conductive adhesive), ACA (anisotropic conductive adhesive) and ICA (isotropic conductive adhesive):

All three systems being developed had to fulfil a number of requirements concerning:
-Adhesion Strength
-Bubble free layers
-Printability
-Dispensability
-Ion concentration
-Curing conditions

NCA are the basic systems for ACA and ICA respectively. In addition they can be used for a special flip chip technology developed at IMEC.
