PCB or the printed circuit board stands for the complex meshwork of circuits arranged in a panel that connects the sheets and acts as one. Several flexible printed circuit board manufacturing companies produce microchips in a bulk amount. The main buyers of these commercial PCBs are the computer industry, motherboard generation, and medical technology. But the fun part is, you can make the PCB boards all by yourself. Here is the complete directory of making a PCB board all by yourself. So, please scroll below to know the process of PCB fabrication and development.
Why Do You Need Homemade PCB
DIY PCB circuits are best for customized designer electronics Because you can cut or add the courses according to your needs. But here, you get the flexibility to choose the material, etch type, concentration, and all the modifiable factors. There are usually two ways of developing a PCB board. One is where you can buy the panels and solder the holes and via all by yourself. In the other one, you have to build it from scratch. Here in this article, you will get to know about the vivid idea of creating a PCB circuit all yourself from the readily available constituents.
First, you have to collect the tools like a mini drill, laser printer, latex gloves, and flat iron. Then you have to get the raw materials A PCB board, etching Solution of ferric oxide, ruler, magazine paper, plastic tweezer, sanding paper, and such.
Building the PCB
First, make a PCB layout that you like according to your need. Designing a PCB layout is as easy as ABC. You can use Microsoft Power point to make the design. Otherwise, there are several paid and free apps to do the job for you more comfortable. Then print out the layout to create a PCB board. Make sure you use the photocopier or a laser printer to bring out the design because the inkjets won’t do the job as the ink is water-soluble. It won’t transfer to the PCB board. In case you already have a pre-built PCB board, then there is no need to replicate this step. This step is for the newbies making a PCB from scratch. Then use the flat iron from the toolbox to iron the layout to the page. The heat will transfer the inks to the board, and you will get an outline of the PCB in the making. You have to set the temperature to the highest if the paper is thick like the magazine paper. Otherwise, you may put it to medium.
Then put the board in a water-filled bowl to let the paper soak and get soggy. Once the step is done, keep it under the running medium faucet and gently rub off the paper leftovers. In this way, only the papers will clear out, leaving the ink intact behind. Now comes the etching. Get a plastic or glass container and half-fill it with ferric oxide for forty to forty-five minutes. Make sure to have the concentration right; otherwise, the ink print will fade away. Then rinse off the etching liquid of ferric chloride with tap water. Get the mini drill and make some holes. Just be careful to make the holes on the copper side if you make a single-layered PCB board. Once you are done, wash it with water again, rinse off the extra ink, and make the corners flattened.
When all steps are completed, and you are good to play with your new PCB chip anyhow, you want. You can customize the design or chip shape according to your taste.
