An electronic component includes a base and a chip attached to the base by a plurality of adhesive pads that are spaced apart from one another and are arranged in an intermediate space between the chip and the base. The chip is electrically connected to interconnects of the base. The adhesive pads are partitioned in a regular distribution over the entire surface area of the chip. A molding compound surrounds the chip and is disposed in the intermediate space between the chip and the base.

An adhesion tape can be used for transferring an adhesive material onto the underside of a chip for further mounting of the chip onto a substrate. In order to provide effective compensation of the curvature of the wafers and of the dies without adversely affecting the mounting process in this case, an adhesion tape having an at least two-layered adhesive layer is provided. The adhesive layer comprises a first and a second adhesive layer. Both adhesive layers can be cured selectively with respect to one another.

A solderable device includes a substrate and a soldering pad overlying the substrate. A solder mask overlies the substrate and portions of the soldering pad. The solder mask has an opening that exposes a portion of the soldering pad. The opening has at least two edges that symmetrically overlie portions of the soldering pad.

Manufacturing method for an electronic component assembly and corresponding electronic component assembly The present invention provides a manufacturing method for an electronic component assembly and to a corresponding electronic component assembly. The method comprises the steps of: providing a substrate having a first and a second side and having at least one through-hole, said second side having a first plurality of solder connection pads; attaching a semiconductor chip to said first side of said substrate; performing a mould process on said substrate and said attached semiconductor chip so as to obtain a mould package, said mould package including at least one first mould section covering said semiconductor chip on the first side and at least one second mould section extending through said throughhole and protruding over said solder connection pads on the second side; and providing a printed circuit board having a surface with a second plurality of solder connection pads corresponding to said first plurality of solder connection pads; and soldering said mould package to said printed circuit board by means of solder balls between said first and second plurality of solder connection pads such that said at least one second section forms a spacer structure supporting said mould package on said surface of said printed circuit board.
摘要:
An electrically conductive connection is produced between a chip and an external wiring configuration that is kept at a distance from the chip by spacers. Electrically conductive contact material is introduced into recesses in the external wiring configuration in order to produce the electrically conductive connection. This can be carried out economically, and allows a mechanically very robust electrical connection from the chip pads to the external wiring planes.

The electronic component has a semiconductor chip embedded in a plastic compound. The electronic component is produced by first producing a number of electronic components on a panel and subsequent dicing into single electronic components. The semiconductor chip of this component is disposed on a substrate the includes or is entirely formed of plastic and it is embedded in a plastic package molding compound. The plastic of the substrate has a glass transition temperature range which is lower than the glass transition temperature range of the plastic package molding compound.

The invention relates to an arrangement for improving module reliability, in particular the reliability of soldered connections on semiconductor products with BGA or BGA-like components to a substrate on which chips are attached by a die attach material, in particular substrate-based IC packages, solder balls mounted on the side that is opposite from the chip, on contact pads of the substrate on a patterned copper foil, being provided for the electrical connection to printed circuit boards, and the chip and the substrate on the chip side being encapsulated with a mold cap. With the invention, it is intended to provide an arrangement for improving module reliability with which stress acting on the solder balls during alternating thermal loading is reduced. According to the invention, an intermediate layer (3) which consists of a compliant or flexible material is arranged at least between the contact pads (2) and the substrate (1) or the printed circuit board.
