Abstract:
A method for encapsulating a chip on a carrier comprising:a) positioning the chip on the carrier; b) forming a dam around the chip on the carrier employing a volumetric dispenser, the dam being formed from a thermosetting material at a first temperature providing at least partial curing of the thermosetting material; and c) subsequently to forming the dam, pouring a thermosetting material into the space within the dam to encapsulate the chip, the thermosetting material being at a second temperature being a temperature lower than the first temperature; wherein the volumetric dispenser comprises a dispensing mouth positioned above the carrier and movable in two mutually perpendicular directions relative to the carrier to dispense a strip of material having the width and height of the dam and wherein the resulting encapsulated structure is cured to harden the encapsulating material.
