Fine-pitch ball-grid array: A square or rectangular array of solder balls on one surface [3] LBGA: Low-profile ball-grid array: Also known as laminate ball-grid array [3] TEPBGA: Thermally-enhanced plastic ball-grid array: CBGA: Ceramic ball-grid array [3] OBGA: Organic ball-grid array [3] TFBGA: Thin fine-pitch ball-grid array [3] PBGA ...
A grid array of solder balls on a printed circuit board after removal of an integrated circuit chip. Cross-cut section of BGA mounted circuit. A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits.
The next big innovation was the area array package, which places the interconnection terminals throughout the surface area of the package, providing a greater number of connections than previous package types where only the outer perimeter is used. The first area array package was a ceramic pin grid array package. [1]
80-pin ceramic quad flat package (TQFP) – ST6 microcontroller The basic form is a flat rectangular (often square) body with leads on four sides but with numerous variation in the design. These differ usually only in lead number, pitch, dimensions, and materials used (usually to improve thermal characteristics).
CPUs with a PGA (pin grid array) package are inserted into the socket and, if included, the latch is closed. CPUs with an LGA (land grid array) package are inserted into the socket, the latch plate is flipped into position atop the CPU, and the lever is lowered and locked into place, pressing the CPU's contacts firmly against the socket's lands ...
Package on a package (PoP) is an integrated circuit packaging method to vertically combine discrete logic and memory ball grid array (BGA) packages. Two or more packages are installed atop each other, i.e. stacked, with a standard interface to route signals between them.
Embedded wafer level ball grid array (eWLB) is a packaging technology for integrated circuits. The package interconnects are applied on an artificial wafer made of silicon chips and a casting compound. Principle eWLB. eWLB is a further development of the classical wafer level ball grid array technology (WLB or WLP: wafer level package). The ...
A more recent design variation which allows for higher density connections is the dual row micro lead frame (DRMLF) package. This is an MLF package with two rows of lands for devices requiring up to 164 I/O. Typical applications include hard disk drives, USB controllers, and wireless LAN.
