Then you place it on the board and using an iron you heat up the paper – the ink also heats up and sticks to the board. During this process you print out the board image with a laser printer (only this kind of printer can be used) on a smooth surface paper. So, it takes quite a lot of time, but in the end, you can get a high-quality board with fine (0.2 mm, ~8 mils) traces.Īnother method is a “heat transfer”. It takes about 2 hours and even then, you have a board which still needs to be cut to the size and holes to be drilled. Finally, the board goes to etching bath to leave the traces on the board. After that, it goes to NaOH bath where UV exposed photoresist layer is washed off. The process is quite tedious: you have to print out the PCB view on a transparent paper or a film, then place the board (which is also covered with a photoresist layer) with the printed mask under UV light for several minutes. ![]() Quite popular home-made manufacturing process includes an UV light and some chemicals. So, for developing process, when you need one PCB and its layout might be redesigned during assembly or testing, a home made solution is quite logical choice (of course, if you want to do it by yourself). It is not very convenient for developing process, because you will probably need only one PCB manufactured and shipped as soon as possible and, in this case, it will be quite expensive. Overall this manufacturing solution in my opinion is acceptable when you need more than one final version PCB. If you want to get them as fast as possible, you will have to pay for more expensive shipping (20-30 USD). If you want to get it for the smallest price – you will have to choose the cheapest shipping, which can additionally cost around 5-10 USD. Usually, 10 small PCBs could cost about 5-10 USD. It only needs to be ordered from one of the PCB manufacturers (which I have shown in this post). It is the easiest way, because it does not require any manufacturing work to be done by you. Let’s start from the probably simplest method – to order PCBs from a professional manufacturer. So, why you should use a CNC router to cut a PCB instead of using other methods? Engraving, drilling and cutting the board.So, this post/tutorial is going to be about how to make a PCB with a CNC router. Although a professional board is a good solution for a finished project, it might not be a convenient solution while you are still in the development process and there might be changes in the board’s layout. I have already talked about how to make yourself a professionally made board in this DIY generator’s post. When you are making some DIY device, you will approach a point when you will have to decide whether to use of the shelf, prebuilt or fully assembled boards or to make your own. ![]()
