柔性线路板（FPCB)韧性及弯折疲劳强度测试仪3FDF 别名：疲劳测试仪 耐弯折测试仪 疲劳强度测试仪 弯折次数测试仪 Model 3 FDF Fatigue Ductility Flex Tester Toroidal Winding Machine Determines Ductility and Flexural Fatigue for Flexible Printed Wiring for Copper and Aluminum Foils or Other Non-ferrous Foils
Universal's Model 3FDF Fatigue Ductility Flex Tester has been developed as a means of testing according to recommendations in the IPC Test Methods manual, 19-23. Operation Samples are pleased in an upright position by six rollers with the mandrels moving vertically between the rollers, subjecting the upper sample surface to tensile strains on the upward stroke. The samples are held in precise position relative to the mandrels by a weight, which also serves to assure conformance of the sample to the mandrel curvature. This weight, 250g for circuits and 100g for foils, subjects the samples to non-zero mean tensile stresses which are small enough to be insignificant. The mandrels are high accuracy rods having diameters ranging from 0.5 to 50mm. The tester has a 0 to 1000 cycle per minute and may be operated in either a "continuity" or a go/no-go mode. Manufactured in the U.S.A. by the makers of the most complete line of toroid winding machines in the world.
