2. Jump wire - Wikipedia

   en.wikipedia.org/wiki/Jump_wire

   Stranded 22AWG jump wires with solid tips. A jump wire (also known as jumper, jumper wire, DuPont wire) is an electrical wire, or group of them in a cable, with a connector or pin at each end (or sometimes without them – simply "tinned"), which is normally used to interconnect the components of a breadboard or other prototype or test circuit, internally or with other equipment or components ...

3. Jumper (computing) - Wikipedia

   en.wikipedia.org/wiki/Jumper_(computing)

   These wires are called wire bridges or jumpers, but unlike jumpers used for configuration settings, they are intended to permanently connect the points in question. They are used to solve layout issues of the printed wiring, providing connections that would otherwise require awkward (or in some cases, impossible) routing of the conductive traces.

4. Wire wrap - Wikipedia

   en.wikipedia.org/wiki/Wire_wrap

   Wire wrapped backplane of an IBM 1401 computer, introduced in 1959 A modern wire wrap in a CFL. Manually wrapped wires were common in early 20th century point-to-point electronic construction methods in which a strong connection was needed to hold the components in place. Wires were wrapped by hand around binding posts or spade lugs and then ...

5. Potting (electronics) - Wikipedia

   en.wikipedia.org/wiki/Potting_(electronics)

   Many sites recommend using a potting product to protect sensitive electronic components from impact, vibration, and loose wires. [2] In the potting process, an electronic assembly is placed inside a mold (the "pot" [3]) which is then filled with an insulating liquid compound that hardens, permanently protecting the assembly. The mold may be ...

6. Surface treatment of PTFE - Wikipedia

   en.wikipedia.org/wiki/Surface_treatment_of_PTFE

   Polytetrafluoroethylene (PTFE), better known by its trade name Teflon, has many desirable properties which make it an attractive material for numerous industries. It has good chemical resistance, a low dielectric constant, low dielectric loss, and a low coefficient of friction, making it ideal for reactor linings, circuit boards, and kitchen utensils, to name a few applications.

7. 66 block - Wikipedia

   en.wikipedia.org/wiki/66_block

   A split-50 M-type 66 block with bridging clips attached. A 66 block is a type of punch-down block used to connect sets of wires in a telephone system. They have been manufactured in four common configurations, A, B, E and M. [a] A and B styles have the clip rows on 0.25" centers while E and M have the clip rows on 0.20" centers.

8. Bonding jumper - Wikipedia

   en.wikipedia.org/wiki/Bonding_jumper

   [2] Some codes require a bonding jumper to be pulled into non-metallic conduit or in electrical metallic tubing that may be exposed to corrosion or mechanical damage. In North American electrical codes, an important bonding jumper is found in main electrical panels, where the system neutral conductor is connected to earth ground. This must be ...

9. Polishing (metalworking) - Wikipedia

   en.wikipedia.org/wiki/Polishing_(metalworking)

   The removal of oxidization (tarnish) from metal objects is accomplished using a metal polish or tarnish remover; this is also called polishing. To prevent further unwanted oxidization, polished metal surfaces may be coated with wax, oil, or lacquer. This is of particular concern for copper alloy products such as brass and bronze. [2]
