Test Strips: Pure Nickel PN: 270NI

$177.50

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

PN: 270NI 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.

Plating Procedure

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 should be immersed until only about 1″ remains above the solution level.

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.

NOTE: 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.
