A uniform cylindrical deposit of one-sided thickness t changes diameter by 2t. Include retained layers and preparation removal in sequence, then review the final limits using the actual deposit range and form requirements.

The process name alone is not a guarantee. Verify solution access, exchange and reaction conditions, then measure the required positions at the entrance and along the depth.

Local maximum growth can coincide with the substrate upper limit along the mating path. Cylindricity, straightness or a masking step can also interfere, so check the functional envelope and local distribution separately from the mean.

An ideal uniform deposit on 60-degree thread flanks changes pitch diameter by approximately 4t. Actual release requires final gauging that reflects thread class, local deposit, profile and lead.

It can be informative under controlled, location-matched conditions, but preparation removal, form changes and thermal differences may be mixed into the result. Do not use the difference alone to guarantee minimum coating on a required surface; connect it with an approved thickness method.

First compare location and sampled area, layer and density calibration, and section preparation and direction. Align the local region and thickness definition before comparing results with their uncertainties.

Omitted form or thermal effects and inspection uncertainty may still matter. Separate specification limits from the acceptance rule and review a zero-margin condition against process evidence and the measurement plan.

Provide finished and pre-plating drawings, mating parts and clearance limits, layer stack and thickness ranges, masking and rack-contact zones, final processing and inspection methods. Material condition and previous first-article measurements help make the allowance and process review specific.
