|
Fatigue Ductility Flex Tester - 3FDF
Determines Ductility and Flexural Fatigue for
- Flexible Printed Wiring
- Copper and Aluminum Foils
- Other Non-ferrous Foils.
Model 3FDF Fatigue Ductility Flex Tester has been developed
according to recommendations in the IPC Test Methods manual, 19-23.

Operation
Samples are placed 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.
