Abstract

The invention relates to an IC packaging body to load at least an electronic component (wafer), containing: a circuit layout composed of plural lead wires and having plural connector parts; a soldering-resistant layer covering the preset part of the circuit layout and formed with equal-microholes; and plural connector bodies in these equal microholes, clinging to and connected with the conductive parts, respectively. Therefore, the circuit layout can be connected together by the equal connector bodies and the electronic component (wafer).

Description

technical field [0001] The present invention is related to electronic products, in particular to an integrated circuit packaging body. Background technique [0002] figure 1 and figure 2 An existing IC package carrier (IC package carrier) 90 is shown, which includes a substrate (substrate) 91, one or both sides of which have a circuit layout (conductor pattern) composed of a plurality of copper traces (copper traces) 93 92 , and the circuit layout 92 is covered with a solder mask 94 . Usually a predetermined portion of the solder resist layer 94 will be removed, so that the predetermined portion of the wire 93 of the circuit layout 92 is exposed, and then nickel and gold plating 95 is plated on the surface of the exposed wire 93, so that, That is, pads 96 forming the circuit layout. [0003] When the integrated circuit package 90 is electrically connected to a die 97 by wire bonding, please refer to image 3 As shown in FIG. 4 , gold wires 98 can be used to connect the...
