Abstract:
A method is provided for assembly of a micro-electronic component, in which a conductive die bonding material is used. This material includes a conductive thermosettable resin material or flux based solder and a dynamic release layer adjacent to the conductive thermoplastic material die bonding material layer A laser beam is impinged on the dynamic release layer, adjacent to the die bonding material layer, in such a way that the dynamic release layer is activated to direct conductive die bonding material matter towards the pad structure to be treated, to cover a selected part of the pad structure with a transferred conductive die bonding material. The laser beam is restricted in timing and energy, in such a way that the die bonding material matter remains thermosetting. Accordingly, adhesive matter can be transferred while preventing that the adhesive is rendered ineffective by thermal overexposure in the transferring process.
