ASSEMBLY AND METHOD OF PLACING THE ASSEMBLY ON AN EXTERNAL BOARD

摘要

The assembly comprises an electronic device (20) that is attached to a first side (11) of a carrier substrate (10) with solder connections (18). The first side (11) of the substrate (10) is provided with bond pads (15) and a solder resist layer (16). The space between the substrate (10) and the electronic device (20) is filled with an encapsulant (19) The substrate (10) further comprises contact pads for connection to an external board. The solder resist layer (l6) is patterned according to a pattern that includes an aperture (161) adjacent to a first bond pad (15). This aperture (161) is ring-shaped and forms the circumference of the first bond pad. Herewith, delamination is prevented, also if a via (142) is present in the substrate (10) below the bond pad (15).
