Article: If you experience significant trauma (fall or car accident) and feel severe pain especially in conjunction with a cracking sound or swelling then head to the nearest hospital or walk-in clinic for medical attention. If a weight-bearing bone is hurt, like in the leg or pelvis, then don't put any pressure on it. Instead, get assistance from someone nearby and get a ride to the hospital, or call for an ambulance to come pick you up. Common signs and symptoms of a broken bone include: intense pain, a visibly deformed or misshapen bone or joint, nausea, limited mobility, numbness or tingling, swelling and bruising. X-rays, bone scans, MRI, and CT scan are tools that doctors use to help diagnose broken bones and their severity small stress fractures may not show up on x-ray until the related swelling abates (up to a week or so). X-rays are most commonly used for the diagnosis of traumatic fractures. If your broken bone is considered complicated there's multiple fragments, the skin is penetrated by the bone and/or the pieces are grossly misaligned then surgery will likely be necessary. Before a broken bone can be casted, sometimes it must be put back together and straightened to its original shape. In many cases, the doctor will use a simple technique called "reduction", which involves pulling on the ends of the bone (creating traction) and manually fitting the pieces together. With more complicated fractures, surgery is required and often involves the use of metal rods, pins or other devices for structural support. Cast immobilization with a plaster or fiberglass cast is the most common treatment for a broken bone. Most broken bones heal quicker when properly repositioned, compressed and immobilized. Usually the doctor will initially put on a splint, which is like a partial cast typically made of fiberglass. A full cast will usually be put on in 3-7 days after most of the swelling is improved. Casts are made of a soft padding and a hard covering (such as plaster of Paris or more commonly, fiberglass). They usually need to stay on for between 4-12 weeks, depending on which bone is broken and how badly. Alternatively, a functional cast (such as a plastic boot) or a supportive brace may be used instead of a hard cast it depends on the type of fracture and its location. Over-the-counter non-steroidal anti-inflammatories (NSAIDs) such as ibuprofen, naproxen or aspirin can be short-term solutions to help you deal with pain or inflammation related to your broken bone. Keep in mind that these medications can be hard on your stomach, kidneys and liver, so it's best not to use them for more than 2 weeks at a stretch. Kids under the age of 18 should never take aspirin, as it's associated with Reye's syndrome. Alternatively, you can try over-the-counter pain killers such as acetaminophen (Tylenol), but don't take them concurrently with NSAIDS without talking to your doctor. Your doctor may give you a prescription for more powerful medications while at the hospital if your pain is severe.

See a doctor immediately. Get a cast or support. Take medications.

Your choice will usually be based on the availability of materials needed by the method, the technical difficulty level of the method or the quality of PCB you desire to obtain. Here's a brief summary of the different methods and their main features that will help you decide: Acid etching method: this method requires extreme safety measure, the availability of many materials such as the etchant and it is somewhat slow. The quality of PCB obtained varies according to the materials you use but generally, it is a good method for simple to intermediate levels of complexity circuits. Circuits involving more close wiring and tiny wires usually use other methods. UV etching method: this method is used for transposition of your PCB layout onto your PCB board and requires more expensive materials that might not be available everywhere. However, the steps are relatively simple and can produce finer and more complicated circuit layouts. Mechanical etching/routing method: this method requires special machines that will mechanically etch away unnecessary copper from the board or route empty separators between wires. It can be expensive if you intend to buy one of those machines and usually leasing them requires the availability of a workshop nearby. However, this method is good if you need to create many copies of the circuit and also can produce fine PCBs. Laser etching method: this is usually used by large production companies, but can be found on some universities. The concept is similar to mechanical etching but LASER beams are used to etch the board. It is usually hard to access such machines, but if your local university is one of the lucky ones having such machine, you can use their facilities if they allow it. For acid etching, you need to draw the circuitry using an etchant resistant material. Special markers can be found easily for this specific purpose if you intend to do the drawing by hand (not appropriate for medium to large circuits). Laser printers' ink is the most commonly used material however. This is usually done by converting your circuit's schematic diagram into a PCB layout using PCB layout software. There are many open source software packages for PCB layout creation and design, some are listed here to give you a head-start: PCB ShortCut Print it out on a glossy paper, such as magazine paper. You should ensure the circuit is mirrored before doing that (most PCB layout programs have this as an option when printing). Once printed, make sure you don't touch the ink part on the paper as it can get on your hands. Start up your iron. Set the iron on the cotton setting and wait until it heats up. Be careful, the paper will be hot. The paper should be stuck to the circuit board, don't rip it out. An alternative approach is to immerse the board and paper in hot water for a few minutes (up to 10 minutes). If certain areas seem particularly difficult to peel off, you can try soaking a bit more. If everything went well, you will have a copper board with your PCB pads and signal lines traced out in black toner. Get the big droplets of water off by softly wiping with a napkin or sponge or just letting them fall out. It shouldn't take more than 30 seconds and it should not be vigorous or else the ink on to the circuit might come off. This process removes any unnecessary copper from the board leaving only wiring of the final circuit.

One-sentence summary --
Choose a method to use for creating the PCB. Create the PCB Layout of your circuit. Once you are happy with the schematic on your computer, match the size of the diagram on the software so that both the circuit board and the paper will have the needed sizes. Print out the diagram from the software's File menu. Align the circuit diagram on the paper with the circuit board (the diagram should be facing the copper part of the circuit board). Once heated, carefully place the iron on top of the paper which is on top of the circuit board. Place the iron there for about 30-45 seconds (depending on your iron). After lifting the iron, put it aside carefully and take the circuit board to your nearest source of water. Start the water flow and hold the circuit board below it. Slowing start taking off the paper and soon all of the paper should come off. Dry the board. Etch the board using one of the methods below.
