PN: 270NIUDF Test Strips Nickel Alloy


We are currently experiencing a disruption in the procudtion of Nickel Test Strips and they are not available for sale at this time. Please note we are working diligently to find an adequate production process and are sorry for this inconvience.

Test Strips: Pure Nickel PN: 270NIUDF

The Bent Strip Method (The Deposit Stress Analyzer System) is approved as ASTM Standard B975.

PN: 270NIUDF This is the most sensitive test strip (pure Nickel 0.0011 inch thick) for tensile and compressive stress, having particular application for low internal deposit stress values. It is ideal for nickel, electroless nickel & nickel alloys, chromium, tin, silver, gold, palladium and rhodium. These test strips measure a range of 200-60,000 PSI.

*These test strips are sold in lots of 25 pcs.

1- This test strip is not for moderate to high alkaline plating baths (the resist will peel off).
2-During plating a test strip is exposed to a uniform current density along the legs of the strip.  The plating test should be continued until the test strip legs deflect up to 20 units and with a target thickness that does not exceed approximately 100 microinches for the most accurate results.  Very low stress may show only 1-2 units.

Recommended Plating Conditions for Nickel Test strips: (this is just a starting point- if the test strip legs do not spread a slightly longer plating time may be required. Plate no longer than 4 minutes).

Temperature 140°F

Current Density  30 Amps/square foot

Plating current .025 Amps

Plating Time: 2 Minutes

Deposit Thickness  50 Microinches

Stress Characteristics

IMG_4051IMG_4036 IMG_4040IMG_4037

The deposit stress is compressive if the resist is on the outside of the Test Strip legs.

The deposit stress is tensile if the plating is on the outside of the Test Strip legs.

Test Strip Tensile Stress Compressive Stress Range, PSI Composition
1194 Yes Yes 1,500 - 145,000 Copper-Iron Alloy
270NI Yes Yes 200 - 60,000 Pure Nickel

Plating Procedure Using the PN:  800L

Plating Procedure

Best results are obtained with a test set up similar to the above photograph. Anodes should be located at least three inches away from the Test Strip and should be positioned in a parallel plane with the Test Strip. Electrical contact should be made at the top of the Test Strip where there is a void in the masking material. The Test Strip legs should be fully submersed with out touching the bottom of the plating cell.

The plating current density should be adjusted with a given electrolyte so as not to cause deposit burning at the Test Strip’s tips, yet sufficient enough to conduct a rapid test. Preferably, the current density should be maintained at the approximate value at which the bath is normally worked.
