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.

Runner system for supplying molding compound

An apparatus and process are provided for molding electronic devices in a mold, which apparatus comprises at least one runner in the mold connected to a mold supply pot for channeling a molding compound from the mold supply pot to the electronic devices. A plunger assembly is also provided that comprises a main body, and a supplementary body configured to be movable relative to the main body. The plunger assembly is locatable in the mold supply pot and is drivable in a direction towards the runner for forcing the molding compound into the runner. In order to avoid or reduce cull formation, a width of the runner at an opening connecting the runner to the mold supply pot is smaller than a width of the main body of the plunger assembly.

Method and apparatus for molding with reduced cull formation

An apparatus and method for degating is provided for separating excess molding material from encapsulated electronic packages while the electronic packages are located in a molding system. At least one holding device is coupled to a mold of the molding system, which is located such that excess molding material is molded onto at least a portion of the holding device during molding. A locking feature on the portion of the holding device locks the excess molding material such that the holding device may hold the excess molding material molded onto it to forcibly separate the excess molding material from the encapsulated electronic packages after molding.

Apparatus and method for in-mold degating

A molding system for provided which is configured for molding a substrate comprising a plurality of individual carriers each of which is pre-cut into a shape of a memory card device and connected to a frame of the substrate by narrow tie bars. A molding plate is configured to receive the substrate, and a cavity plate configured to be clamped to the molding plate further comprises a plurality of molding cavities each constructed in the shape of the said carriers. The cavities are operative to create molded packages onto the carrier conforming to a shape of the memory card device without need for further forming of the molded compound after molding. Additionally, a nozzle on the surface of each cavity is operative to introduce molding material into the cavity in a direction that is substantially perpendicular to a plane of the substrate placed on the molding plate.

Memory card molding apparatus and process

The present invention provides a molding system as well as a method for encapsulating semiconductor packages, wherein a cavity plate is kept at a desired temperature during molding. The system includes a mold comprising a first mold piece and a second mold piece adapted to define a mold cavity for enclosing one or more semiconductor devices for molding, and a cavity plate adapted for mounting in the cavity to introduce encapsulation material to the semiconductor device(s). The system also includes retaining means adapted selectively to hold the cavity plate against the first mold piece or the second mold piece whereby to maintain the cavity plate at the desired temperature.

Molding system for semiconductor packages

Molding apparatus ( ) is provided for simultaneously molding a molding material around a number of separate substrates, each substrate having a semiconductor chip mounted thereon. The apparatus includes a mold holder ( ) having a first holding section for holding a first mold half ( ) and a second holding section for holding a second mold half ( ). The first and second holding sections have a common support surface ( ), the support surface ( ) including a first movable member ( ) in the first holding section and a second movable member ( ) in the second holding section. The first and second movable members ( ) are movable between a first position in which they protrude out of the support surface ( ) and a second position in which the protrusion from the support surface ( ) is less than in the first position. A first drive mechanism ( ) is coupled to the first movable member ( ) and a second drive mechanism ( ) is coupled to the second movable member ( ). The first and second drive mechanisms ( ) are adapted to be independently actuated to move the first and second movable members ( ) between the first and second positions.

Molding apparatus

A mold ( ) for a semiconductor chip ( ) has two mold halves ( ). One mold half ( ) includes sealing means ( ) adapted to exert a sealing pressure between a surface of the mold and a surface ( ) of a substrate ( ) located in the mold ( ) during a molding operation.
