Chromium etchant - FAQs

Undercutting of Chromium etchant can be reduced by increasing the rate of stirring or agitation.

No, Chromium etchant is a ready-to-use solution. Dilution will only be necessary if you want to reduce the etch rate.

The etch rate of Chromium etchant can be reduced by adding 1 part deionized water to 2 parts etchant. This will reduce the etch rate approximately 50%.

The etch rate of Chromium etchant will approximately double with every 10 degrees Celsius increase in temperature. The etch rate can also be increased by increasing the rate of stirring or agitation.

The etch rate of Chromium etchant at 40 degrees Celsius is 40 Angstroms/sec.
