Class Vocabulary

Vocabulary TermDefinition
60/40 Solder that is 60% tin (Sn) and 40% lead (Pb). It is one of the most commonly used solder alloys.
63/37 Solder that is 63% tin (Sn) and 37% lead (Pb). It is a commonly used solder alloy that works especially well on small electronic parts.
bottom-only A type of lead on an electronic component that is located underneath the component.
bridging Excess solder that joins two or more adjacent pads on a PCB, creating a faulty electronic connection.
capacitor An electronic component that stores an electrical charge.
clinched Bent into a desired shape.
CMOS Complementary Metal Oxide Semiconductor. CMOS is the semiconductor technology that is currently used for manufacturing processors and memory. Most personal computer and consumer electronics chips are some variant of CMOS.
conductive Able to act as a path for the movement of electricity.
consumer electronics Electronic equipment intended for use by everyday people. Consumer electronics usually find applications in entertainment, communications, and office productivity.
copper trace A conductive path on top of a PCB made of copper. The copper trace is embedded on the surface of a PCB and forms a circuit when electronic components are soldered to it.
crimp To pinch, bend, or press into a desired shape.
diode A solid-state device that allows electricity to flow in only one direction.
DIP Dual-inline package. An integrated circuit with two rows of external connecting terminals or pins, which are inserted into the holes of the printed circuit board. DIPs are well-suited for automated assembly into printed circuit boards.
DIPs Dual-inline package. An integrated circuit with two rows of external connecting terminals or pins, which are inserted into the holes of the printed circuit board. DIPs are well-suited for automated assembly into printed circuit boards.
dual inline package An integrated circuit with two rows of external connecting terminals or pins, which are inserted into the holes of the printed circuit board. DIPs are well-suited for automated assembly into printed circuit boards.
electronic circuit Any complete pathway through which electrical current can flow. Electronics incorporates the use of semiconductor devices for a wide range of products including computers, cell phones, and radios.
electronic component A basic electronic element usually packaged in a discrete form with two or more connecting leads or metallic pads. Components are intended to be connected together, usually by soldering to a printed circuit board, to create an electronic circuit with a particular function.
electrostatic discharge Current produced by two objects having a static charge when they are brought close enough together to produce an arc or discharge, as static electricity. Electrostatic discharge can cause simple skin irritation for a person or destroy a semiconductor electronic device.
epoxy fiberglass A combination of epoxy and fiberglass that is used in coatings, adhesives, and PCBs.
fillet The rounded, concave section of the joint where the solder material bonds the component to a surface.
flat pack A flat integrated circuit with its leads projecting from all four sides of the package without radius.
fully clinched A lead with the end bent to a 90 degree angle.
grounding A means of providing a safe path for electricity should it stray from its intended path.
gull wing lead An SMT lead that is shaped like the outstretched wing of a seagull.
hot-air desoldering station A soldering station with a hot air pencil for desoldering delicate surface mount components.
housing A protective cover designed to contain or support a mechanical component.
inductor A passive electronic component that stores energy as a magnetic field.
integrated circuit A complete electronic circuit within a single component. Its name resulted from the integration of previously separate transistors, resistors, and capacitors, all on a single chip.
inward-formed L A type of lead on an electronic component that curls underneath the component at an angle similar to the letter L.

lifting A defect in which layers or parts of a PCB or component are lifted or pulled out of place.
mask A coating on a PC board, usually dark green or dark blue, that is designed to insulate and protect the copper traces and keep them from shorting together. The mask is "masked out" to form solder pads to allow for soldering separate component leads.
on-board termination Leads that end on the surface of the PCB.
packaging A protective cover designed to contain or support a mechanical component.
pad A copper platform to which surface mount components are soldered.
