An apparatus and method is provided for forming a board-on-chip (BOC) package. An adhesive material including a carrier and microcapsules distributed in the carrier is used to bond a semiconductor component to a mounting surface in a BOC package. The microcapsules contain a hardener and/or a catalyst that, when combined with the carrier, initiate a bonding reaction. The contents of the microcapsules are released via application of an external influence, such as pressure or heat, when the bonding reaction is desired to begin. The use of microcapsules permits the formulation of adhesive blends with a substantially increased pot life, increased stability and reliability at high temperatures, and favorable low temperature reaction and bonding characteristics.
