Abstract:
A compound carrier board structure of Flip-Chip Chip-Scale Package and manufacturing method thereof provides a baseplate having a flip region with a through-opening and bonding to a Non-conductive Film to bond to a carrier board in order to form a compound carrier board structure. Therefore, when a die is planted in the film region of the carrier board structure, the carrier board is able to susceptible to different stresses during a package process. The baseplate uses the low Thermal Expansion Coefficient material to avoid warpage problems caused by the thermal expansion of the carrier board resulting from the thermal stresses. The carrier board is able to disperse conduction of thermal stresses by the baseplate in order to strengthen cooling effect of the compound carrier board structure. Thus, the present invention achieves miniaturization and heat strengthening and enhances the mechanical strength.
Abstract:
Disclosed is a method of packaging a chip and a substrate, including the steps of forming a substrate with a thickness ranging from 70 to 150 μm, which comprises a dielectric layer, a circuit metal layer stacked on the dielectric layer and bonding pads higher than the dielectric layer by 10 to 15 μm; forming a stabilizing structure around the substrate to provide a receiving space; disposing the chip on the receiving space and bonding the pins of the chip with the bonding pads; and filling up the receiving space under the chip with a filling material to a total thickness ranging from 300 to 850 μm. Without the plastic molding process, the present invention reduces the cost and the total thickness, and further prevents the substrate from warping by use of the stabilizing fixing structure.
Abstract:
A laminate circuit board with a multi-layer circuit structure which includes a substrate, a first circuit metal layer, a second circuit metal layer, a first nanometer plating layer, a second nanometer plating layer and a cover layer is disclosed. The first circuit metal layer is embedded in the substrate or formed on at least one surface of the substrate which is smooth. The first nanometer plating layer with a smooth surface covers the first circuit metal layer. The second nanometer plating layer is formed on the other surface of the substrate and fills up the opening in the cover layer to electrically connect the first circuit metal layer. The junction adhesion is improved by the chemical bonding between the nanometer plating layer and the cover layer/the substrate. Therefore, the circuit metal layer does not need to be roughened and the density of the circuit increases.
