PN: 1194UDF Test Strips Copper Alloy


PN: 1194UDF Test Strips: Copper Iron 

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

These Test Strips are made from Copper-Iron Alloy material 0.002 inch thick for tensile and compressive stress, deposit stress determinations between 1,500-145,000 psi.

Important: Each unit ordered includes 25 test strips.

If testing compressive or tensile deposit stress we have some copper alloy test strips available for a limited time with resist alignment issues.  They are PN:  1194UDFBR cost is $ 6.20 each sold in lots of 25 pcs.  Call the office at 717-428-0186 or email

*If purchasing more than 500 pcs. contact the office (717-428-0186 or e-mail for a bulk discount.

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.

These Test Strips are not for moderate to high alkaline plating baths.

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

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.

Two Anodes are required, similar in composition, shape and size. Anodes 2x2x1/8″ can be purchased from Kocour Company.

Note: For Electroless Nickel activation is not required for Chemically induced metallic deposition.
