Abstract

The invention provides a packaging structure and a packaging method. The packaging structure comprises a circuit substrate, at least one wafer, a plurality of pins and a packaging colloid. The circuit substrate is provided with a first surface and a second surface which are opposite, wherein the circuit substrate is provided with a plurality of contacts on the first surface. The wafer is arranged on the second surface of the circuit substrate and electrically connected with the circuit substrate. The plurality of pins are arranged on the periphery of the second surface of the circuit substrate to encircle the wafer. Each pin is provided with an inner pin part and an outer pin part, and each pin is electrically connected with the circuit substrate through the inner pin part thereof. The packaging colloid wraps the circuit substrate, the wafer and the inner pin part of each pin and exposes the first surface of the circuit substrate and the outer pin part of each pin, wherein the upper surface of the packaging colloid is coplanar with the first surface of the circuit substrate.

Description

technical field [0001] The invention relates to a packaging structure and a packaging method, and in particular to a packaging structure and a packaging method with good process compatibility and system integration capabilities. Background technique [0002] Reducing the volume of integrated circuit component products has been one of the long-standing goals of the electronics manufacturing industry. The shrinkage of the product volume means the reduction of the production cost, and also means the shortening of the signal transmission path, and at the same time brings the advantages of the improvement of the product performance. [0003] One of the key factors affecting the volume of integrated circuit components is the improvement of packaging technology. Nowadays, the packaging method using a leadframe as a chip carrier is still quite popular and widely used. Quad Flat Package (QFP) structure is a common example. [0004] With the improvement of process capability, multi...
