One or more electronic devices that are mounted on a substrate, including at least one cooling plate in contact with the one or more electronic devices, are encapsulated. The substrate is clamped between a first mold half and a second mold half which define a molding cavity for molding the one or more electronic devices. A cavity insert movably located in the first mold half is projected into the cavity in order to contact and apply a sealing pressure onto the at least one cooling plate. After introducing a molding compound into the cavity at a first fill pressure, the molding compound in the cavity is packed by applying a second fill pressure which is higher than the first fill pressure. During this time, the sealing pressure is maintained at values that are higher than the first fill pressure and the second fill pressure.

Encapsulation process for double-sided cooled packages

An apparatus having a seal plate which includes rigid hard portions and one or more flexible soft portions located between the hard portions is used for bonding at least one semiconductor device onto a substrate that is supported on a platform. The seal plate is movable between a first position which is spaced from the substrate and a second position whereat a first side of the seal plate is configured to be in contact with the substrate. A diaphragm covers a second side of the seal plate opposite to the first side. A fluid pressure generator exerts a fluid pressure onto the diaphragm to actuate the diaphragm to compress the one or more soft portions to transmit a bonding force onto the at least one semiconductor device during bonding.

Flexible sinter tool for bonding semiconductor devices

A molding system for molding electronic components mounted on first and second sides of a substrate has a molding cavity onto which the substrate is locatable for molding. The molding cavity has a first section covering a molding portion of the first side of the substrate, and a second section covering a molding portion of the second side of the substrate. First and second pots have plungers for compressing molding compound placed therein. First and second runners connect the first and second pots to the first and second sections of the molding cavity for introducing the molding compound onto both sides of the substrate. In particular, the runners extend at least from an edge of the substrate along both sides of the substrate to the molding cavity.

Dual-sided molding for encapsulating electronic devices

The invention provides an apparatus, for processing a semiconductor device, comprising a first tool which comprises a pressure application component, a guide, and a spacer moveable in the guide. A gap is defined between the spacer and the guide and is operable to allow the spacer to tilt in relation to the guide. The apparatus also comprises a second tool for holding the semiconductor device, wherein the first and second tools are moveable relative to each other between an uncoupled state and a coupled state. The spacer comprises a first portion proximate the pressure application component, wherein in the coupled state, the pressure application component is operable to apply a force as a first pressure to the first portion. The spacer also comprises a second portion distal from the pressure application component, wherein in the coupled state, the second portion is proximate the semiconductor device and is operable to transmit the force from the pressure application component to the semiconductor device as a second pressure.

Apparatus and method for processing a semiconductor device

A molding apparatus for an electronic device comprises a first mold chase, a second mold chase and a middle plate which is configured to be clamped together with the electronic device between the first mold chase and second mold chase during molding. A molding cavity formed in the middle plate is configured for receiving molding compound. A package pin is mounted on the middle plate to be movable with the middle plate, and a portion of the package pin is positioned to protrude into the molding cavity to form a mark in the molding compound when molding compound is molded around the said portion of the package pin.

Apparatus for molding electronic components

A runner system for a molding apparatus comprises a plurality of runner networks, each runner network further comprising a mold supply pot having a first side and a second side opposite to the first side. A plurality of molding cavities are located on the first and second sides of the mold supply pot, and a plurality of runners are operative to channel molding compound from each mold supply pot to the plurality of molding cavities. At least one of the mold supply pots comprises a different number of runners located on the first side which are connected to the mold supply pot as compared to a number of runners located on the second side which are connected to the mold supply pot.
