what is the difference between bga and lga
Land grid array LGA packaging is related to ball grid array (BGA) and pin grid array (PGA) packaging. Unlike pin grid arrays, land grid array packages are designed to fit either in a socket, or be soldered down using surface mount technology. PGA packages cannot be soldered down using surface mount technology. In contrast with a BGA, land grid array packages in non socketed configurations have no balls, and use flat contacts which are soldered directly to the PCB. BGA packages, however have balls as their contacts in between the IC and the PCBs. The balls are normally attached to the underside of the IC.
Team GB Team GB is the brand name used since 1999 by the British Olympic Association (BOA) for their Great Britain and Northern Ireland Olympic team. The brand was developed after the 1996 Summer Olympics, and is now a trademark of the BOA. It is meant to unify the team as one body, irrespective of each member athlete's particular sport. It forms part of a marketing strategy, where its brevity is seen as beneficial. The brand is seen as controversial by some, for focusing on Great Britain, at the expense of Northern Ireland, with critics suggesting it be changed to Team UK, something the BOA has so far rejected.
