IPC 620 ANSWERS AND QUESTIONS SET A+
✔✔recovered diameter - ✔✔diameter of shrinkable products after heating has caused it
to return to its extruded diameter
✔✔reference edge - ✔✔the edge of a cable or conductor from which measurements are
made
✔✔rework - ✔✔the act of reprocessing noncomplying articles, through the use of
original or alternate equivalent processing, in a manner that assures compliance of the
article with applicable drawings or specifications
✔✔RF connector - ✔✔connector used for connecting or terminating coaxial cable
✔✔Sealing plug - ✔✔a plug that is inserted to fill an unoccupied contact aperture in a
connector insert. its function is to seal, especially in environmental connectors
✔✔sheath - ✔✔the outer covering or jacket of a multiconductor cable
✔✔shell - ✔✔the outside case of connector into which the insert and contacts are
assembled
✔✔shield coverage - ✔✔the physical area of a cable that is covered by the shielding
material and is expressed in percent
✔✔Electronic shielding - ✔✔a physical barrier, usually electrically conductive, that
reduces the interaction of electric or magnetic fields upon devices, circuits, or portions
of circuits
✔✔short shot - ✔✔insufficient filling of the mold tool during molding process
✔✔sink marks - ✔✔a depression in the molded material that is caused by uneven
cooling/solidification of the molded part
, ✔✔solder wicking - ✔✔capillary movement of solder between metal surfaces, such as
strands of wire
✔✔solderless contact - ✔✔a contact with a back portion that is a hollow cylinder which
allows it to accept a wire. After a bared wire is inserted, a crimping tool is applied to
crimp the contact metal firmly against the wires, usually called a crimp contact
✔✔solderless wrap - ✔✔the connecting of a solid wire to a square, rectangular, or V-
shaped terminal by tightly wrapping a solid-conductor wire around the terminal with a
special tool
✔✔splice - ✔✔a joint connecting conductor with good mechanical strength and which
provides good conductivity
✔✔strain relief - ✔✔a technique or item which reduces the transmission of mechanical
stresses to the conductor termination
✔✔strain relief clamp - ✔✔an adjustable collar, usually secured by a nut and bolt that
clamps the wire or cable attached to the connector so as to relieve the strain on the
contact terminations
✔✔strand group - ✔✔a bundle or collection of strands that make up a single conductor
or wire
✔✔nicked strands - ✔✔strands that have been partially cut or broken but are still
attached, Severed strands have been out or broken to where they are no longer
attached
✔✔scrapped strands - ✔✔strands have neem damaged due to stripping instrument
✔✔streaking - ✔✔discoloration of the part usually fanning out from the injection gate
✔✔stress relief - ✔✔a predetermined amount off slack to relieve tension in component
or lead wires OR the portion of a component lead or wire lead that is formed in such a
way as to minimize mechanical stresses after the lead is terminated
✔✔surface imperfections - ✔✔rough surfaces on the molded component
✔✔tab - ✔✔the flat blade portion of certain terminals OR on strip terminals, the
projection that results when the point-of-shear is not flush with the terminal body
✔✔tensile - ✔✔amount of axial load required to break or pull a wire from the crimped
barrel of a terminal, splice or contact
✔✔recovered diameter - ✔✔diameter of shrinkable products after heating has caused it
to return to its extruded diameter
