Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H 2 SO 4), water, and hydrogen peroxide (H 2 O 2), used to clean organic residues off substrates. Neither shaking the bottle nor stirring in the bowl induced the solids to go back into solution. Photrak™ is ideal for today's high yield, low cost, fine line, multilayer PCBs. Placing my glass object into the solution gave an uneven, spotted frosted effect that looked like a dog had drooled hydrochloric acid onto it. Adding water to acid can be hazardous, but Modutek has developed a safe procedure to add the required water to the acid bath. Cops are well aware that it's a corrosive acid and will consider you dangerous. Photrak™ is a new generation liquid Photoimageable etch resist that offers a low cost, high quality alternative to dry film. This description uses the Klyr-Koat liquid flux as the resist and nitric acid for the etching bath. After the sgraffitoing the liquid flux coat is fired. Etching/Chemical Milling… Panels are then fed through one of our Chemcut etching … It is this hardness that provides […] You can get charged for a lot more than vandalism if you get busted with etch. etchall ® Updates. Other Related Knowledge. However, once you've etched a board with it, you're left with a solution with a bunch of coppe… This fired coat of enamel is the resist for the etching. Because the mixture is a strong oxidizing agent, it will remove most organic matter, and it will also hydroxylate most surfaces (add OH groups), making them highly hydrophilic (water-compatible). AN210L Liquid Alkaline Aluminum Etch: AN210L is a proprietary liquid aluminum etch, designed for ease of use. By the time it arrived, my bottle of Etch Bath had separated into watery liquid and rocky sand. Stop Using Ferric Chloride Etchant! Viscosity of matte etching bath is decreased and therefore drag- out losses are minimized – reducing the caustic soda losses into the waste water treatment plant. ... ALUMAL ETCH AB 212 – Liquid, immersion or spray, addition agent blend of surfactants to improve cleaning efficiency of alkaline etching or alkaline etch clean systems. ): Ferric chloride is a traditional home-use circuit board etchant. Easily added to the bath by tank-side additions or metering, AN210L eliminates the dusting often associated with powdered etch. (A Better Etching Solution. Remember that using etch can really heat up your name. After coating the metal with the liquid flux, the dried coat is sgraffitoed to expose the metal that will be etched. It's easy enough to come by, and the Ferric by itself is no big environmental problem. Would you like to receive email updates for new etching products, specials, tutorials, and more? The Modutek Nb series etch bath includes a condenser which returns some of the steam back to the bath, but water has to be added to the bath to replace the steam that escapes.
