Removal of enamel from ultrafine monofilamentary wires

Abstract

Various techniques for stripping the insulation from very small ͑e.g., 30 m diam͒ single-strand wires ͑made of copper-as in the case of magnet wire, phosphor bronze, manganin, etc.͒ without damaging them are discussed. Such approaches include the use of dissolutive chemicals, heat, short-wavelength laser radiation, and rotating friction wheels. A small handheld instrument that employs the last of these methods, and is capable of stripping wires with diameters ranging from 30 to 330 m, has been developed and is described in detail.

A new probe to monitor the effects of drugs on local field potentials

“…1A), is placed 2.5 mm away from the tip of the first one, but the inter-tip distance can be freely adjusted to the size of the structure to be microdialyzed. Two ultra-thin insulated wires (Nichrome/Formvar, bare diameter: 0.0020 in., coated diameter: 0.0026 in., A-M Systems, Inc.), each 20 cm in length, are cut and a short segment of wire insulation is removed by abrasion (see Walker, 2004). At one end of the wires, 3 mm of insulation are removed, and the wire soldered to a D-Sub crimp connector (Jameco, USA).…”

A transcranial magnetic stimulation coil using rectangular braided Litz wire

“…To avoid damaging the ultrafine wires, the ETFE layer was removed using a rectangular wire stripper (Eraser L2SA). The enamel film was removed using Corrosive Caustic Soda melted in a hot pot (Eraser DSP1) at 400 ˚C and then the wire was cleaned and neutralized using Ammonium Chloride and Citric Acid [24].…”

Stripping of PFA Fluoropolymer Coatings Using a Nd:YAG Laser (Q-Switch) and an Yb Fiber Laser (CW)

“…The studies of PFA coatings for laser removal found in the literature have had different objectives. There have been works for stripping electrical cables [22,23,24] and for stripping electronic components [25]. Excimer ultraviolet lasers and titanium–sapphire lasers in the infrared field have been used in cable stripping.…”
