A commonly used wave solder fluxing method in which flux foam is generated from a liquid flux by means of a porous diffuser, such as a hollow cylindrical stone.
The terminal is stamped and folded or formed into its final shape.
A sleeve used to compress a grommet, which tightens a seal around a wire entering the connector.
The difference between operating and releasing force.
A common format among connectors throughout the industry that encompasses different points. Form factor defines things such as location of contact rows with respect to the PC-board, modular sizing, and mating length.
The process by which a material is bent to provide the required shape of a terminal. This is done after the terminals have been blanked and plated. In pre-plated materials, blanking and forming are performed in the same die in one process.
A solid state arrangement or active circuit element/device of two different types of semiconductors, bonded together, that creates an interfacial junction or depletion layer that allows electrical current flow only in the direction of the current of the external voltage source circuit, i.e., when the polarity of the external voltage source adds to the internal barrier potential polarity of the depletion layer.

Fiber Optic Test Procedures
A form of miniature SC package that has ribbon leads on two or four sides, typically on 0.050" centers.
Flat Printed Circuitry
Field Product Deficiency Report
A fast packet-switching approach designed to replace X.25 for linking LANs across WANs. Frame relay is faster than X.25 because it does not perform many of X.25's functions. Frame relay and X.25 are both connection-oriented packet-switching techniques, in contrast to SMDS, which is a connectionless, fast packet-switching technique.
In fiber optics, a cable mounted connector that joins source-to-optical conductor, optical conductor-to-optical conductor, or optical conductor-to-detector.
Maximum value of impedance in a transmission line, also equal to the radio/TV wave impedance through air or vacuum which is 377 ohms. Also known as Free space intrinsic.
Analysis of a signal waveform in the domain of frequency using Fourier Transforms which de-convolutes or transforms a signal from the Time Domain (i.e., as a waveform of voltage ( or current) - time plot of the signal waveform) into its complementary frequency components or spectrum.
See Time Domain.
An instrument used to measure cycles per second of a recurring event, wave, or oscillation. Measurements made in Hertz.
A common method of radio or television broadcasting in which the frequency of the radio wave is changed above and below its central frequency. The changes in the frequency of the carrier wave, when detected, represent the information transmitted.
Normally, the 50 or 60 cycle power available in residential areas.
The characteristic of a device denoting the range of frequencies over which it may be used effectively.
In fiber optics, losses incurred at the terminus interface due to refractive index differences.
A condition in which mated surfaces move slightly and continually expose fresh metal. The exposed metal oxidizes and builds up until electrical continuity of the system is broken.
A connector in which plug and receptacle are prevented from separating only by the force of friction.
In fiber optics, finely ground glass used to join glass to metal or other glasses. Also called solder glass, it may or may not devitrify during temperature cycles.
Flame Retarding Moisture Resisting finish
Written wiring instructions in the form of a list indicting termination points.
In connector technology, the mating end of a metal terminal.
Scaling parameter for any mathematical function in various equations.
A connector is front mounted when it is attached to the outside or mating side of a panel. A front mounted connector can only be installed or removed from the outside of the equipment.
Connector contacts that are released from the front side of the connector. A removal tool engages the front portion of the contact and pushes it out the back, where it is removed by hand.
A user interface panel that could consist of any of the following switch or display assemblies:
Fiber to the Curb
A component placed on the crimping cycle of crimping tools forces the tool to be fully closed, thereby completing the crimping cycle before the tool can be opened.
A diode circuit that utilizes both positive and negative alternations of an alternating current to produce a direct current. Changes all of the AC into DC, creating an almost perfect DC current flow.
Crimped terminal or splice barrel that opens to facilitate quick and easy wire insertion.
A block designed for cartridge fuses. Some are fitted with a neon or incandescent fuse failure indicator and may be mixed with feed-through models on the same standard assembly vail.
Single plastic insulated wire. 125 in, 60° C, 18-20 AWG.
