Ceramic bga package.

An array of bare lands only. Ceramic bga packages also work well with flip chips in general. Having a very high melting point this type bga requires c4 approach controlled collapse chip connection for making the bridge between bgas and pcbs. In addition to alumina al 2 o 3 ceramics we produce aluminum nitride aln with high thermal conductivity 150w mk as well as low temperature co fired ceramic ltcc packages with high 12 3ppm k and low 3.

In a bga the pins are replaced by pads on the bottom of the package each initially with a tiny solder ball stuck to it.

Flip chip hitce ltcc bga package kyocera provides both ceramic and organic packages for large scale integration lsi devices. The bga is descended from the pin grid array pga which is a package with one face covered or partly covered with pins in a grid pattern which in operation conduct electrical signals between the integrated circuit and the printed circuit board pcb on which it is placed.

Cbga ceramic ball grid array. The solder balls have a 90 percent lead and 10 percent tin composition to increase reliability and overcome the issues of the differences between the thermal coefficients of expansion of the substrate and board.
