A microarray package includes a leadframe having an array of contact
posts, a die carried by the lead frame, and a plurality of bonding wires
that electrically connect the die to the lead frame. An encapsulant is
included that encapsulates the die, the bonding wire and the leadframe
while leaving the distal ends of the contact posts exposed and
substantially co-planar with a bottom surface of the microarray package.
A plurality of pedestal members is plated to the distal end of a
respective contact pad. A distal surface of each pedestal member
protrudes outwardly beyond the bottom surface of the microarray package
in the range of about 15 .mu.m to about 35 .mu.m.
