Abstract: A carrying structure is provided and is defined with a main area and a peripheral area adjacent to the main area, where a plurality of packaging substrates are disposed in the main area in an array manner, a plurality of positioning holes are disposed in the peripheral area, and a plurality of positioning traces are formed along a part of the edges of the plurality of positioning holes, such that the plurality of positioning traces are formed with notches. Therefore, a plurality of positioning pins on the machine can be easily aligned and inserted into the plurality of positioning holes by the design of the plurality of positioning traces.

Abstract: A chip carrier structure is provided and defined with a chip carrier region and a wire bonding region, and the chip carrier structure includes: an insulating layer; a circuit layer formed on the insulating layer; a solder mask layer formed on the insulating layer and the circuit layer and having a plurality of openings in the wire bonding region; and a protective layer formed on a portion of the circuit layer exposed from the solder mask layer, where an area of the protective layer in each of the openings is less than 70000 ?m2. By reducing the areas of the circuit layer exposed from the openings and the protective layer exposed from the openings, the problem of delamination caused by poor bonding force between the materials of the protective layer and the circuit layer is greatly reduced, thereby improving the reliability and lifespan of the chip carrier structure.
