So naturally, I tried it.Whenever I have made circuit boards in the past, I did it just like most of us do. Give yourself some room to grow over time. Me. )its a great chemical if you know how to use it. ("Do like you oughta, add acid to water" to minimize the chance of an out-of-control exothermic reaction.) BTW to drill the holes I used a standard bench press, cranked the speed to its maximum (3000 rpm) and mounted a portable fluorescent light with a lens to help me locate the holes. Hexahydrated Ferric Chloride (EN - SDS) Datasheet. The spent solution contains cupric acid, that can be concentrated by evaporation and used in an etching tank. Laser printer with plenty of toner 4. This isn't rocket surgery.5) I do have an aquarium pump ($6 at fish store) that I've used to re-activate my solution. (The stuff that crafters use to etch glass) I googled for it and didn't find any, but maybe someone more switched in to the DIY PCB scene might have seen something on a BBS somewhere? £3.79 £ 3. When I'm etching a board with copper chloride, I'll pour a couple extra inches of solution into the container. With is that all about? Then I realized I forgot to print the pads on this thru-hole board. Once the pH has risen above 7 the etchant is neutralised. I busted one of them because I got too tired and forgot to let the press up before moving the board - snap! (And it's prettier too. How did you clean and/or prepare the board's surface beforehand? This is the PCB Etching solution used to remove the copper from a PCB. 4.3 out of 5 stars 8. Sounds cheap and environmentally friendly to boot. We are offering Ferric Chloride Anhydrous (FeCl3) For PCB Etching to our clients. I put the ferric chloride into a small tub, dropped the masked circuit board into the solution, and rocked it back and forth for a long time. This concentrates the copper in solution, giving you a stronger etchant. Safet… I wouldn't recommend it anyway. However, ferric chloride is an attractive spray etchant because of its ease of use, holding capacity for copper, and the ability to be used in infrequent batch applications. I am a bladesmith just getting into making Damascus and need an etching solution to show the pattern in the steel. If you've got a 750 milliliter container, start out with less than 500 milliliters of solution. Each Hazardous Item: There maybe additional transit time on this item. Find great deals on eBay for ferric chloride solution. You grab it from any chemist hey, I used to use it in my younger years to tint my hair, oh how I miss having hair.Anyway, hit up your local dischem, checkers pharmacy or even click may have it. (See video. It's easy enough to come by, and the Ferric by itself is no big environmental problem. ): Ferric chloride is a traditional home-use circuit board etchant. It's reusable anyway, and the extra exposure to oxygen just regenerates it. RoHS Status: Not Applicable Statement of conformity. That's the end etchant.Eventually you etch so much that you convert all the CuCl2 into CuCl, which doesn't dissolve copper (and is a yucky brown color). (It's the stuff they use to make blonds.) after that, i tried to put another pcb and I can see reaction, I let the pcb submerged in it for a few minutes without doing anything, not even touching anything. you could also let it dry out crystallize to store dry. I assume the PCB copper plate is of size 4x4 inches and you have a ground plane on PCB. The exposed copper left on the board must be removed by use of an etching material, or etchant, such as ferric chloride, a yellow orange dark salt.
