Terminology
Adhesive dispensing: a computer-controlled machine automatically dispenses epoxy adhesive.
Backmolding: this term refers to the process of transfer-molding epoxy performs into a old. The epoxy is heated and pressurized, much like
Backpotting: the application of epoxy to connector wire terminations for strain relief and sealing. Epoxy is dispensed with pneumatic
Brady labels: wraparound adhesive labels for multi-conductor cable.
Breakout: the area where one or more cables are joined together. A breakout frequently requires splices and extra strain relief such as cable
Electrical testing: Hi-pot, insulation resistance, and continuity testing are standard tests for cable assemblies.
Etching: etching is a chemical process to prepare certain types of Teflon insulated wire for potting. Without etching, the epoxy will not bond
Expando: braided sleeving used to protect a wire bundle. The simplest and least expensive method of jacketing a cable, expando tubing is
Header: a general term for any printed circuit board mounted connector used as an I/O port.
Hot stamping: insulated wire is imprinted with identification numbers or text.
Hot-stamped heat shrink tubing: used for multi-conductor cables, heat shrink tubing is impression stamped, then installed on the cable and
Ink-jet marking: dots of ink are sprayed through a stationary nozzle onto a part moving on a conveyer. Ink jet marking is now standard.
Ink-stamping: the traditional method of placing metal type in a marking machine which is inked with a roller. The metal type transfers the ink
Jumper Cable: this term usually applies to a short cable assembly that plugs into a printed circuit board one one end, with the other end
Lacing: the process of tying individual wires together into bundles. Special lacing tape is used.
Laser stripping: insulation is removed from the wire by using a special laser stripping machine. Typically used on flat cable.
Mass-termination: simultaneous termination of multiple contacts. Normally associated with IDC termination, mass termination is also used on
Pigtail: a single-ended cable assembly having one connector on one end and unterminated wire on the other end.
Potting: the application of various adhesives to a connector. Potting encapsulates the wires or terminals, providing environmental sealing and
Silkscreening: Ink is transferred through a screen.
Stripping: insulation is removed from wire ends on automatic cut and strip equipment.
Thermal Shock: a conditioning environmental test that cycles a part repeatedly through a specified temperature range. Thermal shock is fre-
Tinning: the application of molten solder to connector terminals. Micro products are tinned on a fully automatic machine with cleaning, pre-
Wire marking: individual numbered adhesive tags are attached to each wire.
Wire striping: insulated wire from #24 thru #28 AWG is striped with colors for circuit identification.
Wiring fixtures: flat wiring boards or more complicated three-dimensional fixtures are required for many multi-branched cable harnesses.
