In an FCBGA package, the die is mounted upside-down (flipped) and connects to the package balls via a substrate that is similar to a printed-circuit board rather than by wires. FCBGA packages allow an array of input-output signals (called Area-I/O) to be distributed over the entire die rather than being confined to the die periphery. [ 9 ]
Bare die supplied without a package. It is mounted directly to the PCB using bonding wires and covered with a blob of black Epoxy. [22] Also used for LEDs. In LEDs, transparent epoxy or a silicon caulk-like material that may contain a phosphor is poured into a mold containing the LED(s) and cured. The mold forms part of the package. COF: Chip ...
Each WonderWorks building is designed to look as if an existing building was ripped free of the ground by severe weather and dropped upside down on its roof. This unique design is credited to the Orlando architect Terry O. Nichoson of Nichoson Design International, at WonderWorks' original Orlando location.

In a piece for the New York Times, Ron Lieber explains the benefits of walking away from a home you're underwater on: "In an economic environment like this one, however, the consequences of giving ...
A portrait of Major John Andre remains upside down at the '76 House in Tappan. General George Washington turned it over when Andre was hung as a spy after giving the plans of West Point to ...
Flip chip packages often consist of a silicon die sitting on top of a "substrate" which then sits on top of a traditional PCB. The substrate can have a Ball Grid Array (BGA) on its underside. The substrate makes the connections to the die available for use by the PCB. [11]
At the other extreme is "dead bug" style, with the ICs flipped upside-down with their pins sticking up into the air like a dead insect, the leads of components are usually soldered directly to other components where possible, with many small circuits having no added wires. While it is messy-looking, free-form construction can be used to make ...
