Abstract
This webinar reviews etchant used in the PCM industry, data has been abstracted from twenty-five years of PCMI surveys on etchant usage and materials etched.
This webinar reviews etchant used in the PCM industry, Data has been abstracted from 25 years of PCMI surveys on etchant usage and materials etched. The information presented details:
• Pros and cons of etchant selection;
• Best practices;
• Lowering of costs/environmental impact by etchant regeneration; and
• Health, safety, and disposal issues
for the six most commonly-used PCM etchants (ferric chloride, ferric nitrate, cupric chloride, hydrofluoric acid, potassium ferricyanide, and iodine/potassium iodide).).
Please go to page 66 to read “Exploring the Different Etchants Used in the PCM Industry,” a paper submitted by David Allen to help prepare attendees for this webinar discussion relative merits of etching copper alloys with cupric chloride rather than ferric chloride.
