Ball-grid arrays (BGA) are IC packages, which place output pins in the form of a solder ball matrix. The traces of the BGA are generally fabricated on laminated substrates (BT-based) or polyimide-based films. Therefore, the entire area of substrates or films can be used to route the interconnection. BGA has the advantage of lower ground or power inductance thereby assigning ground or power nets via a shorter current path to PCB. Thermally enhanced mechanisms (heat sink, thermal balls, etc.) can be applied to BGA in order to reduce thermal resistance. The higher functional capabilities of the BGA package technology benefit high power and high speed ICs that require enhanced electrical and thermal performance. Compared with traditional SMT packages, the advantages of BGA are as follows:

  • Higher interconnect density
  • Lower assembly cost
  • Self-alignment during reflow
  • Lower profile
  • Ease of thermal and electrical management
  • Ease of routing

Heat Slug BGA (HSBGA) is an upgraded type of PBGA. Within the molding area, a piece of copper heat slug is implanted. The heat slug is intended to lower the thermal resistance (θJA) of PBGA without change of material. The θJA of HSBGA is generally 20% lower than PBGA and achieves 5 to 6W of thermal dissipation under natural convection. This technology can be applied to any kind of die-up substrates (e.g. 2- or 4-layer BT, and metal core). HSBGA is an excellent solution for cost-effective high power package, high-speed ICs like graphics chips, communication and networking ICs.

Application

HSBGA is excellent for products that require improved thermal performance such as high power packages for high speed ICs in personal computers, networking and graphic ICs, data communication, consumer ICs and in telecommunication applications.

Fine pitch Ball Grid Array (FBGA) are BGA package that follows JEDEC standard package outline dimension for DRAM products. To meet high speed DRAM requirement, FBGA can be designed the shorter trace length to provide better electrical performance than that of TSOP. Not only better electrical performance, FBGA's smaller package size allows higher memory density on memory module than that of TSOP package.
