Ball grid array. La matriz de rejilla de bolas 1 o BGA (en inglés ball grid array) es un tipo de encapsulado montado en superficie que se utiliza en los circuitos integrados, por medio de una serie de soldaduras las cuales se llevan a cabo mediante el calentamiento de bolillas de estaño o alguna otra aleación tipo SAC (por la normativa ...
12 de sept. de 2022 · As you can see, all the pins are on the processor chip. On the other hand, a PGA socket on the motherboard looks like this: An easy way to recall what kind of processors LGA and PGA indicate is by using their names – Land Grid Array and Pin Grid Array. LGA – Land, i.e., Flat CPU with no pins, motherboard sockets with pins.
Description [ edit] The land grid array is a packaging technology with a grid of contacts, 'lands', on the underside of a package. The contacts are to be connected to a grid of contacts on the PCB. Not all rows and columns of the grid need to be used. The contacts can either be made by using an LGA socket, or by using solder paste. [2]
Land grid array (LGA) és un tipus d'encapsulat de circuit integrat utilitzat com a interfície física dels microprocessadors Intel Pentium 4, Intel Xeon, Intel Core 2 Duo i AMD Opteron.
平面網格陣列封裝. 平面網格陣列封裝 （英語： LGA, Land grid array ）是一種 積體電路 的 表面安裝技術 。. 其特點在於其 針腳 是位於 插座 上而非積體電路上。. LGA封裝的晶片能被連接到 印刷電路板 （ PCB ）上或直接 焊接 至電路板上。. 與傳統針腳在積體電路上 ...
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. The whole bottom surface of the device can be used, instead of ...
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 and ensuring a good connection, as well as ...
