A Comprehensive Guide to CABGA (Chip Array Ball Grid Array)

CABGA or Chip Array BGA or CA Ball Grid Array serve as a packaging technology. It is mainly used in microprocessors and Integrated Circuits or ICs.

In the packaging of CABGA, the IC, thus mounted over the ceramic substrate, surrounded with various tiny solder balls. However, the package arranges these solder balls in a pattern of grid array over the bottom surface of a package. They usually create connections between the PCB and the IC.

The package of CABGA gained popularity because of its high reliability, high thermal conduction, and greater pin count. These features make this technology ideal to use in devices that need high processing performance and high speed, like networking, advanced computing, and telecommunications.

Structure Of CABGA (Chip Array Ball Grid Array)

The technology of CABGA packaging’s structure comprises a ceramic substrate. It gives a strong and stable base alloy to the IC, with a greater number of ting solder balls. The package arranges these solder balls in the form of a grid pattern over the bottom surface of the package.

However, ceramic substrate incorporates the IC over it using flip-chip or wire bonding technology. At the same time, tiny solder balls help in creating a connection electrically between the surface of the PCB on which it is mounted and the IC.

Moreover, the number of solder balls number in CABGA packaging may vary from hundreds to many thousands based on the certain requirements of an IC.

Advantages Of CABGA (Chip Array Ball Grid Array)

BGA Chip
