| BGA (Ball
Grid Array) package is a method of reducing package size and pin-to-pin
trace gap. This results in the integration of more functions and reliability
in a single space. BGA typically uses a polymide-based organic substrate
for die and wire attachment. This substrate incorporates metallized
trace routing for connection of the die to the system board through
solder balls, instead of metal leads used in leaded packages. |
| |
| TBGA is extremely
useful for high-speed devices because of the shrinkage of wiring length
due to its superior wiring density of flex circuitry.With capability
rapidly approaching 20-um lines and spaces, a ball-array pattern that
would require two, or even four layers of circuit board to route can
now be implemented on a single layer of flexible substrate. |
| |
| Two-metal
layer TBGA having signal/power layer and ground plane layer on each
side of the dielectric film, which can achieve superior electrical
properties, is strongly recommended for high performance TBGA package. |
