silk screen (optional) silk screen part numbers or what ever you want on your board. The peroxide is normal 3% for mouthwash or cleaning cuts, and can be bought at a drug store for $2-3 for a big bottle. Your board will etch suspiciously fast, but don't worry, that's what is supposed to happen! drill: again surface mount doesnt need this so skip it. Then … Zdravka Karaguiozova . to do this you must sand/steel wool the pcb. Let us know in the comments below or post up a thread in the forum for posterity. As I am no chemist, reproduced below is some chemical information concerning cupric chloride etching. take a center punch and punch where you need holes. Cuppric chloride, CuCl2(H2O)2, is another PCB etchant that is actually made by etching copper in a mixture of HCl and H2O2. step three place pcb in solution (i will go over how to prepare a pcb soon), step four add the salt to activate the mixture (the salt can also be used to speed up the etching. my board failed because i used less vinegar tan i should have. ammonium persulfate, 220 gram added to 1 liter of water and mix it until everything is dissolved.Theoretically it should be possible to etch slightly more than 60 grams of copper with 1 liter etching solution. If you want to get the maximum amount of copper into your cupric chloride solution, check out this awesome tutorial. Instead, she combines vinegar, hydrogen peroxide, and salt. Just post a picture on the corkboard of a project you have made or are currently working on. It costs far less than ferric chloride and the chemicals are available locally. This green color will grow deeper with each use. now that you have your board you need to... tin: add solder paste to board. Did you make this project? Etching liquid are mainly copper chloride solution, ferric chloride liquid, alkaline etching, … Do not laser etch your moleskin notebooks. PCB etching with 37% H2SO4 (Sulfuric acid) + 30% H2O2 (Hydrogen peroxide) mixed at about 1:1 ratio. The hard part is figuring out the perfect ratios of chemicals once you start etching. Etching your own circuit boards is tons of fun, but etching requires strong chemicals to dissolve the copper plating on blank circuit boards. Want to master Microsoft Excel and take your work-from-home job prospects to the next level? How do you etch your boards? This video covers etching circuit boards with a mixture of muriatic acid and hydrogen peroxide. after that dont touch the sanded side. Someone test using sulfuric acid etching agent - hydrogen peroxide do to corrosion outer graphics. White vinegar is about 5% acetic acid, and when it is mixed with an equal part of 3% hydrogen peroxide it is supposed to make an efficient etchant. Using this system requires a reliable control system, for both components required to replenish the system, Hydrogen Peroxide, and Hydrochloric Acid. Jump-start your career with our Premium A-to-Z Microsoft Excel Training Bundle from the new Gadget Hacks Shop and get lifetime access to more than 40 hours of Basic to Advanced instruction on functions, formula, tools, and more. I think it's a natural evolution from breadboard prototyping, to semi-permanent perfboard or stripboard projects, to etching your own circuits at home, to sending your designs to a PCB fab house. (That's for another instructable.) Sulfate as the base of etching solution, after use, the copper can be separated with electrolytic method, thus can be reused. As a side not, melting PVC can also release chlorine gas. if you want to see more from me check out my you tube: https://www.youtube.com/channel/UCdx-DwcKCAiSY-hxtei4sYQ contact m…, Digital Measuring Roller Using Microbit & Tinkercad, Pocket Dice! After the first etch, you should notice the solution starting to acquire a light green tint. But I was somewhat concerned about using toxic, corrosive, skin-burning acids like muriatic or environmentally problematic etchants like Ferric Chloride at home. If you have any questions, suggestions, or corrections, feel free to message me personally. You can monitor the hydrochloric acid content by testing the conductivity of the solution just like with our automatic garden project! step 2(optional) use a dremel to cut down to size. Plastic/Glass Vessel for carrying out the reaction….. (Don’t use steel or aluminium) I like to use a beaker. Re: Etching PCB with vineager and Hydrogen peroxide in an earthenware dish?

If you can pull all this off, you will essentially have a factory grade etchant at your disposal that doesn't need to be carefully disposed of because you can reuse it. step two mix 50 50 hydrogen peroxide and vinegar. The ingredients are cheap and available. The release of chlorine and hydrogen gas make this impractical for indoor use. Etching solutions for pcb. But [Quinn Dunki] just wrote up her PCB etching guide and she doesn’t use either of those. You'll also need a non-metallic container that fits your PCB and two standardized measuring cups. There you are, done! I have seen people try to etch with the following four solutions: vinegar and peroxide hydrochloric acid and peroxide home brewed ferric chloride cupric acid. PCB Etching with Hydrogen Peroxide + Hydrochloric Acid (H2O2 + HCl) [4K] Thermosphere. Electrochemical experiments showed that the etching process is most probably purely chemical. Note: the ratios of mixing given here are based on volume of solution. Sep 2, 2016 #2 gramps said: I use muratic acid and hydrogen peroxide to etch boards, and it works to my satisfaction. First some background: I'm a newbie to etching(like that, in bold). Adding hydrogen peroxide can release chlorine gas. In this case, safety will come after very careful and precarious chemistry, so If you decide to take this project on, always wear chemical grade protective gear for your hands, body, and face. #9 Dec 08, 2014, 02:18 am Last Edit : Dec 09, 2014, 01:59 pm by dave-in-nj This is an alternative to using ferric chloride. Yay for safety. step one for etching a pcb is ig gather hydrogen peroxide ,vinegar, and salt. This is the copper that has dissolved into the solution. Hydrogen Peroxide will be available in any drug/medical stores too. Place your board to be etched in your new solution and watch it go! Both solutions contain water and the etching reaction itself produces water. The remaining resist left on the copper will protect the pattern from being etched, while the exposed copper will be stripped off. Scroll to continue with content. In this paper, the etching behaviour of germanium in hydrogen peroxide solutions is described. solder mask: if you have any solder mask you can add it now (if you do dont tin the board). Mix two-parts of diluted hydrogen peroxide with one-part muriatic acid. Pcb Etching Solution: step one for etching a pcb is ig gather hydrogen peroxide ,vinegar, and salt.step two mix 50 50 hydrogen peroxide and vinegar.step three place pcb in solution (i will go over how to prepare a pcb soon)step four add the salt to activate the mixture (… PCB Etching. During it's first phase, it gives off chlorine gas in quantities that coulld be dangerous in small spaces - ventilate well. Be sure to enclose your entire acid tank so that no light can get in and break down the hydrogen peroxide. Like the PCB manufacturing in Fusion PCB of Seeed. There you are, done! Mix two-parts of diluted hydrogen peroxide with one-part muriatic acid. With the artwork pattern transferred to the copper, the PCB is now ready to be etched. The hydrogen peroxide acts as an oxidizer allowing the acid to eat away the copper. Hydrogen Peroxide I.P from a medical store or chemical shop (conc is about 20 Vol so that’s around 6% i think) Hydrogen Peroxide. Muriatic acid is just a 30% solution of hydrochloric acid in water. As long as you're in the hardware store, pick up some acetone if you don't already have some. HYDROGEN PEROXIDE/SULPHURIC ACID ETCHING SOLUTION . 2. You would have to calibrate the desired voltage based on empirical tests with etching speeds, but in theory, you can monitor the HCL level using an Arduino analog input. All projects are welcome. This is a quote directly from RD Chemicals: "The Hydrogen Peroxide (H2O2) system of replenishing has been popular in the Photochemical Milling industry. If we can get the chemical rations stabilized with an Arduino dispenser setup, I will have an infinite etch tank and never need to handle etchant acids again! However the duration of etching process was not even : the shortest method is Ferric chloride rubbed (3 minutes) followed by Ferric chloride bath (10 minutes), Salt/Vinegar/Hydrogen Peroxide has the longest etching duration (11 minutes when rubbed and 20 when PCB is immersed). If you didn't catch that, messing up this solution can cause the release of chlorine gas which is a chemical weapon and quite nasty. The mixture will start to get slightly warm from the reaction. i just etched my initials on the board(GT).. now my board didnt turn out well but i can still save it. mixture of hydrochloric acid and 1/2 cl hydrogen peroxide – prefer FeCl as it has less acidic fumes OR ferric chloride and of Hydrogen peroxide OR The etching solution is 2 parts hydrogen peroxide (available at any drug store) and 1 part muriatic acid (available This is done by removing the excess copper from the copper laminate, only leaving the required circuit on it. Always perform dangerous chemistry outside or under a fume hood. Because of its low corrosion rate, generally in the actual production, but is expected to be in no chloride etching. muriatic acid (25% hydrochloric acid) into a glass jar, its color should be clear. I plan on doing some more experiments with this etchant in the near future. the melt a small amount os solder to smear on the board(you dont need alot). The oxidation ability of hydrogen ion in hydrochloric acid is lower than that of copper ion. PCB Etching; Currently used for print circuit board etching of solvents are iron (Ferric Chloride), cupric chloride (Cupric Chloride), alkaline ammonia (Alkaline Ammonia), sulfuric acid hydrogen peroxide (Sulfuric Acid + Hydrogen Peroxide) etching fluid, ammonium persulfate, sulfuric acid – chromic acid etching solution. Ferric chloride produces little to no fumes and can … Do not mess with adding lots of hydrogen peroxide to your solution unless you have a reliable way of measuring the solution contents. Share it with us! Keeping the ratio of hydrogen peroxide to hydrochloric acid is rather difficult over the course of multiple etchings. Here is my example entry. I am sorely lacking in chemistry knowledge, but one thing did catch my eye about cupric chloride etching. Don't forget! Ferric chloride Stable in storage. The developed PCB is etched with a 220 g/l solution of ammonium peroxydisulfate (NH 4) 2 S 2 O 8 a.k.a. It is used in pools and as paint thinner, among other things. My question is, has anyone been able to re-energize their muratic acid / hydrogen peroxide etching solutions? drill your holes where center punched its not that hard. If you have a higher concentration of hydrogen peroxide, be sure to dilute it to 3% before mixing anything. Store the etchant solution in an airtight opaque container to maintain the ratio of chemicals. Muriatic acid is available at most hardware stores. Keywords: Hydrogen peroxide, sulphuric acid, etching, copper. We are currently accepting entries into our photo contest for a chance to win your very own lucid dreaming goggles kit! Hydrogen peroxide is a strong oxidant, much stronger than iron trichloride. The use of Hydrogen Peroxide also produces a purer Cupric Chloride, without Sodium Chloride (NaCl) impurities, but the Hydrochloric Acid level must be carefully monitored, as it is consumed in the regeneration part of the reaction. the sanding removes any oxidation and grease from your fingers off the board. I used a pyrex glass 1 litre jug as the mixing bowl with that sitting in a bowl of water to help cool the solution if things got too hot. Neither hydrogen peroxide nor hydrochloric acid can be used to corrode the panels. (this part is optional) use the dremel to mill copper of the unused side this will make etching easier and faster. Luckily, we can whip up our own etchant at home with everyday chemicals! Carefully place the cooled piece of oxizided copper into the jar, it will change the … The hydrogen peroxide acts as an oxidizer allowing the acid to eat away the copper. About: Im a self proclaimed gray hat because what i do can or can not be a threat to some one. These meters are not cheap, but they are attainable. Etching is a part of the PCB fabrication process which is used to create the cropper traces on the printed circuit board. Hydrogen Peroxide (3%) and Hydrochloric Acid (37%) are taken in ratio 1:1 unstable in storage. The normal ferric chloride solution works well, but can be expensive and leaves permanent stains. 1. I found that 1 part muriatic acid to 2 parts 3% hydrogen peroxide etches a 1/2 oz copper board in about 3 minutes (heated solution) which is about half the time for ferric chloride. My PCB turned out a dream in only a few minutes. Pour about 11 oz. Use respiratory protection when opening the bottle of acid. If exposed to light, the ratios will be out of balance and your etchant will work at a snail's pace. Better yet, our new etchant will turn an eerie green color rather than the dull brown of ferric chloride. It usually comes in a 3% solution for medical purposes. my solution (2 parts hydrogen peroxide 3% and 1 part Hydrochloric Acic 38%) and mixed in a very short time and began etching. The peroxide-based methods use simple over-the-counter Hydrogen Peroxide to remove all the copper on a PCB. hp1729. Pour two cups of acid in a plastic container and add 1 cup 3% peroxide. Your board will etch suspiciously fast, but don't worry, that's what is supposed to happen! The etchant lasts about a day. Joined Nov 23, 2015 2,304. Next add your pcb and watch it closely. The dissolved copper creates cupric chloride which can itself be used to etch metal. In this page we will describe about some etching solutions which are little bit safe and cheap they are. Procedure (See the video downside ): This doesn’t require a big amount of chemicals as you would’ve done using FeCl3. Work the output into an Arduino controller and you could automate the dispensing of muriatic acid and hydrogen peroxide to keep your etchant in perfect working condition. Ask Question. Do not touch, breath, or ingest muriatic acid! The hydrogen peroxide is monitored with an oxidation/reduction potential (ORP) meter. Space Research and Technology Institute – Bulgarian Academy of Sciences e-mail: karazuzi@yahoo.com . This suggests that the amount of hydrogen peroxide-based etching waste solution in sodium carbonate is decreased, so that the uniform particle size has progressed due to the fact that the decomposition rate of particles is low by strong acid. We will mix a solution of hydrochloric acid (HCl) and hydrogen peroxide (H2O2), which, when exposed to copper, will oxidize the copper and strip it from the FR4 material. Do not forget eye protection! center punch holes: if your doing sm board (surface mount) skip thus step. This will be fine for etching. This replenishment method also suffers from the fact that over-replenishing with the Hydrogen Peroxide can generate free Chlorine gas.". Hydrogen peroxide is unstable and breaks down very quickly when exposed to light (hence the opaque brown bottle at the pharmacy).
