The medium used to interconnect a number of circuit boards. Typically refers to a special, heavy-duty printed or discrete wired circuit board.

A packaging technology similar to a pad grid array, in which a device's external connections are arranged as an array of conducting pads on the base of the package. However, in the case of a ball grid array, small balls of solder are attached to the conducting pads.

An unpackaged integrated circuit.

Refers to the number of digits in a numbering system. For example, the decimal numbering system is said to be base-10. May also be referred to as the "radix".

A pre-defined group of unconnected components that is replicated across the surface of a gate array.

A method of representing Boolean equations as decision trees.

A form of music characterized by fast tempos and agitated rhythms that became highly popular in the decade following World War II.

A packaging technology similar to a pad grid array, in which a device's external connections are arranged as an array of conducting pads on the base of the package. However, in the case of a ball grid array, small balls of solder are attached to the conducting pads.

A technology in which the function of each logic gate is implemented using low-power CMOS, while the output stage is implemented using high-drive bipolar transistors

Base-2 numbering system.

A method of representing Boolean equations as decision trees.

A form of state assignment for state machines that requires the minimum number of state variables.

A relatively new low-voltage integrated circuit technology in which complex combinations of bipolar and NMOS transistors are used to form sophisticated output stages providing both high speed and low static power dissipation.

A family of transistors.

A system which utilizes two bases, base-2 and base-5, to represent decimal numbers. Each decimal digit is represented by the sum of two parts, one of which has the value of decimal zero or five, and the other the values of zero through four. The abacus is one practical example of the use of a bi-quinary system.

A test strategy in which additional logic is built into a component, thereby allowing it to test itself.

Abbreviation of binary digit.

A family of transistors.

A via that is only visible from one side of the substrate.

A small circle used on the inputs to a logic gate symbol to indicate an active-low input or control, or on the outputs to indicate a negation (inversion) or a complementary signal. Some engineers prefer to use the term bubble.

A mathematical way of representing logical expressions.

A sequence of initialization operations performed by a computer when it is first powered up.

A special pattern etched onto the power or ground plane of a microwire circuit board to be used in conjunction with a laser beam which is employed to create blind vias. The laser beam evaporates the epoxy forming the outer layers of the board and continues down to the bounce pad which reflects, or bounces, it back up, thereby terminating the via.

To unite or fuse two pieces of metal by heating, or with a hard solder with a high melting point.

A test strategy in which additional logic is built into a component, thereby allowing it to test itself.

Refers to some form of media, typically magnetic, such as tape or a disk drive which can be used to store large quantities of information relatively inexpensively.

A via used to link conducting layers internal to a substrate. Such a via is not visible from either side of the substrate.

A set of signals performing a common function and carrying similar data. Typically represented using vector notation; for example, address[7:0].

A set of signals related in some way that makes it appropriate to group them together for ease of representation or manipulation. May contain both scalar and vector elements; for example, {a,b,c,d[5:0]}.

A group of eight binary digits, or bits.
