A ball grid array (BGA) is a type of surface-mount packaging (a chip carrier) used for integrated circuits. BGA packages are used to permanently mount devices such as microprocessors. A BGA can provide more interconnection pins than can be put on a dual in-line or flat package. The whole bottom surface of the device can be used, instead of just ...
Good solder joints between BGA and PCB. Ball grid arrays (BGA) and chip scale packages (CSA) present special difficulties for testing and rework, as they have many small, closely spaced pads on their underside which are connected to matching pads on the PCB. Connecting pins are not accessible from the top for testing, and cannot be desoldered ...
Chip-on-flex (COF), a variation of COB, where a chip is mounted directly to a flex circuit. Tape-automated bonding process is also a chip-on-flex process as well. Chip-on-glass (COG), a variation of COB, where a chip, typically a liquid crystal display (LCD) controller, is mounted directly on glass.
The package interconnects are applied on an artificial wafer made of silicon chips and a casting compound. Principle eWLB. eWLB is a further development of the classical wafer level ball grid array technology (WLB or WLP: wafer level package). The main driving force behind the eWLB technology was to allow fanout and more space for interconnect ...
The die may be mounted on an interposer upon which pads or balls are formed, like with flip chip ball grid array (BGA) packaging, or the pads may be etched or printed directly onto the silicon wafer, resulting in a package very close to the size of the silicon die: such a package is called a wafer-level package (WLP) or a wafer-level chip-scale ...
Chip 1 Exchange is a privately owned electronics company that distributes electronic components. It was founded in 2001 and since then has opened multiple other branches. The company focuses on obsolete and difficult-to-locate components. The company is based in Germany, the United States, Mexico, Brazil, and the Philippines. [1]

For example, in the case of a ball grid array (BGA) package, the pre-deposited solder ball on the package and the solder paste applied to the circuit board may both melt, but the melted solder does not join. A cross-section through the failed joint shows a distinct boundary between the solder ball on the part and the solder paste on the circuit ...
