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.
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 ...
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.
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.
Initially, the impetus behind this recognition and the subsequent development of solutions was the emergence of new semiconductor chip packages such as the ball grid array (BGA) which placed the device's pins beneath the silicon die, making them inaccessible to physical contact with an instrument's or a test system's metal probes.
An example is ball grid array (BGA) using tin-lead solder balls for connections losing their balls on bare copper traces or using lead-free solder paste. Other platings used are organic solderability preservative (OSP), immersion silver (IAg), immersion tin (ISn), electroless nickel immersion gold (ENIG) coating, electroless nickel electroless ...
The packaging materials the company processed include substrate (ball grid array) and lead-frame packages, the testing services provided by the company are based on logic, mixed-signal, and embedded memory devices to measure the performance and reliability of packaged semiconductor devices. In addition, the company also provides turnkey service ...
