Now, place your printed plate inside a bowl of lukewarm water for 10 minutes. After this, remove the paper gently by peeling it. Image 2: An image of copper plating on surfaces to increase the thickness.
First, put on the rubber gloves before placing some newspaper pieces on the bottom to avoid the spillover of the etching solution on the floor. Secondly, find a plastic bowl and fill some water into it before dissolving around ferric chloride powder teaspoons in the water. Thirdly, slowly dip your PCB into the etching solution for close to three minutes. And after that, the ferric acid will react with the unmasked copper to remove the unwanted pieces of copper from your PCB, a process known as etching.
Cleaning is the last step. Here, it would help if you were careful while disposing of your etching solution and other unwanted material. Don't pour it on a pool or a pond. Image 3: An image of copper plating on surfaces to increase the thickness. While trying to create a PCB out of your own hands and equipment is fun, you should be very cautious.
A simple mistake may see you seeking costly medical attention or a few stitches. Since such involves the use of power tools and dangerous chemicals, it's good to be cautious. It is vital to ensure that you wear safety equipment such as protection glasses, gloves, and an apron all the time. I need be, you may be required to do your work close to an eyewash station, a phone, and a first aid box. Before starting the PCB etch process, you may have to make sure that you use all the tools and equipment correctly.
If you aren't sure of anything, go ahead and ask an expert. Image 4: An image of a person soldering a PCB. Lately, a lot of hobbyists are trying out their hand at etching their PCBs. Soldering connects two components on a PCB by melting a filler metal known as solder to create a bond between the two points. As such, solder can be considered the glue that joins electric components on the board.
Important to note that solder also refers to the process through which the filler metal is melted to create the connection. Solder has a lower boiling point than the metal parts they bond. For this reason, soldering entails heating the metal parts to be bonded using a soldering iron and placing the solder on the heated metal to melt it. Solder that connects ends on a PCB board can be made of different materials.
In recent times, safety guidelines and standards have directed the replacement of lead with other less toxic metals. Soldering is a fundamental skill in the context of electronics. Because the optimum functioning of electronic devices and appliances relies on the soundness of a PCB, proper soldering is vital.
This means expert PCB soldering techniques for maximum efficiency. To better appreciate the techniques of soldering, it is important to understand the key steps in a simple PCB soldering task.
Connecting the components of a circuit using soldering can be explained in these four simple steps:. Tinning entails pre-coating the two ends being bonded with solder to make the bonding stronger and longer-lasting.
It provides a smooth surface for the flow of molten solder, making the bond smoother and even. Once the tips are prepared, the soldering iron is used to heat the tips which then melt the solder to create the bond. You need to soak the board to a container of tap water for about mins, or you can rub it will you expose it on running water from the sink. Be sure to wait until the paper on the board becomes soggy, then rub it gently so the ink wont get removed when you rub the paper off the board.
Saw the excess board with a metal saw. Next you need to sand the edges to smoothen the board with sanding paper, kindly use the finer so you will have a finner finish.
Even though you have rubbed the paper off the board there will still be excess paper left on the board, remove it using a very sharp object like the tip of the cutter, the point of a sharp compass or a tooth pick. When you had rub it off or you had sawed the excess board, some of the inked areas had been remove unintentionally, you should restore it with a marker and a ruler.
There are different variety of etching solution but the most common is Ferric Chloride. Get a plastic container, never use any kind of metal container. Pour th etching solution on your plastic container.
Leave the PCB board for about minutes in the container. After for about minutes remove it from the container, leaving it for a long time will etch the ink protected area so please remove it when it's done. Rinse the PCB board with tap water, after etching it in the solution. Be sure to wear glover when cleaning it. It is advised to use plastic tweezers, please do not use metallic materials like pliers or your tool will end up like mine's, its rusty.
First you should brush the remaining ink with laundry soap after etching the board to expose the copper part of the board, or you could clean it with a small piece of sanding paper fine while give it its shiny finish.
Drill the board with a mini drill a dremel tool will do. After drilling it rinse it again with water. Be sure to drill it on the copper side, since the copper layout will be your guide where to drill. Your Done!!! Be sure to clean it before you solder the components.
