A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors . A BGA can provide more interconnection pins than can be put on a dual in-line or flat package .
Thin fine-pitch ball grid array : A square or rectangular array of solder balls on one surface, ball spacing typically 0.5 mm Land grid array (LGA): An array of bare lands only. Similar to in appearance to QFN , but mating is by spring pins within a socket rather than solder.
However, industry leaders Intel and AMD transitioned in the 2000s from PGA packages to land grid array (LGA) packages. [8] Ball grid array (BGA) packages have existed since the 1970s, but evolved into flip-chip ball grid array (FCBGA) packages in the 1990s. FCBGA packages allow for much higher pin count than any existing package types.
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 ...
BGA with an interposer between the integrated circuit die to ball grid array Pentium II: example of an interposer in dark yellow, integrated circuit die to ball grid array chip carrier. An interposer is an electrical interface routing between one socket or connection to another. The purpose of an interposer is to spread a connection to a wider ...
Ball grid arrays (BGA) and chip scale packages (CSA) present special difficulties for testing and rework, as they have many small, closely spaced pads on their underside which are connected to matching pads on the PCB. Connecting pins are not accessible from the top for testing, and cannot be desoldered without heating the whole device to the ...
A coined solder ball is a solder ball subject to coining, i.e., flattening to a shape resembling that of a coin, to increase contact reliability. [ 3 ] Ball grid array , chip-scale package , and flip chip packages generally use solder balls.
Package on a package (PoP) is an integrated circuit packaging method to vertically combine ball grid array (BGA) packages for discrete logic and memory.Two or more packages are installed atop each other, i.e. stacked, with a standard interface to route signals between them.
