Appliance Design - February 2009 - (Page 30) CoNNECtorS & CorDS the Gold 8000 connectors from Fujipoly have low durometer elastomeric cores around which flat mechanical gold-plated connectors are placed in a row parallel to each other. Z-Wrap gold elastomeric connectors from Z-Axis consist of a flexible ultra-fine pitch connector element surrounding an elastomer core. A Z-Axis elastomeric used for a cell-phone chip-on-glass display. Flame-Retardant Cut-Through Resistance Resistant to Solvents, Fuels & Oils Wide Operating Temperature Range Let us make some for you! Varglas Viton® 231 is a flame-retardant sleeving with exceptional physical and electrical properties. It has excellent abrasion and cut-through resistance with flexibility throughout a wide, continuous-operating temperature range of -70°C to 220°C. It is resistant to solvents (aromatic & aliphatic), fuels (including jet fuel JP-5), and oils (including Skydrol). Varglas Viton® 231 is a silicone-free fluoroelastomer / fiberglass sleeving that offers all of this, and more! Varglas Viton® 231 Sleeving is available in three grades in standard black, white and natural in a full range of sizes in coils, cut lengths or on spools. Send for free sample kit. ® DuPont Trademark Under UL’s Component Program, all grades of Varglas Viton® 231 sleeving comply with VW-1 flammability requirements - UL File E53690. Grade A conforms to, and is listed on, the Qualified Products List (QPL) for MIL-I-3190/7, latest revision. Varflex Corporation 512 W.

Within each of the electrically charged layers, metallic particles create thousands of conductive paths and multiple points of contact between mating pads. The non-conductive layers isolate the conductive layers from each other and prevent electrical shorts. For example, when placed between an LCD and PCB, at least one conductive layer will connect to the matched pads, and at least one insulating layer will isolate adjacent circuits. In the second type of construction, very fine wires are wound closely and tightly around the elastomer. The wires can come in a variety of metals, but gold is the most popular because of its low resistance and ability to withstand high dielectric voltage. The wires create the electric paths. A wiretype connector might have 25 wires wound around it, each carrying 2 or more amps. Fujipoly offers the Zebra elastomeric connectors, which are available with carbon or silver conductive fillers. (The company also offers wire construction elastomer connectors that include the option for using gold wire.) The carbon filled silicone products are high resistance, but low-cost products. Resistance can be high as 1,000 ohms. Silver is a more popular connector filler because it is a lowresistance connector that can handle more current. With a 0.05 in. by 0.5 in. contact area, it can handle about 700 mA. They can operate in a temperature range of –40 DegC to 125 DegC. The durometer is 30 Shore A, and the hardness of the conductive portion is set and cannot be custom ordered. Wire-based elastomeric connectors made by Z-Axis are called Z-Wrap Gold and Z-Alloy. Wire-wrapped connectors are considered better options for low-resistance applications. The Z-Alloy has a contact resistance of <0.5 Ohms per contact. The Z-Wrap Gold elastomeric connectors has a contact resistance of <20 milliohms per contact. www.applianceDESIGN.com 30 applianceDESIGN AD02094Varf.indd 1 February 2009 1/14/09 9:46:46 AM http://www.varflex.com http://www.varflex.com http://www.appliancedesign.com
