If you’re working on a project that requires a custom circuit board, then you might opt for a printing service. This negates a lot of the human error that can occur when you create your own. If you want to learn how to design one of these for your next project then you can follow this guide.
What you Need
There are a few things that you’ll need to get started with creating this board. If you want to print and prepare it for yourself, then you’ll need all of the following materials:
- A Dremel
- Heating element (like an iron)
- A laser printer
- Protection for your eyes and hands
- An etching solution
- Your blank board
- A pen
- Tweezers
- High gloss paper
- Sanding paper
- A lint free cloth
Make sure you follow all of the instructions to ensure that you have the right materials. For example, the laser printer must be exact, as an Inkjet printer won’t work for this process. With those in hand, it’s time to move onto the next step.
Designing your Board
The next part of the process is to create the board using PADS PCB Design Software. This allows you to design and run simulations on your new piece of kit, as you create it specifically for your purpose. You can also access a vast component library with this software, cutting down the amount of time you spend on these simple elements.
This unified design is great for hobbyists and professionals alike! Once you’re happy with the design that you’ve created, you can move onto the printing.
Printing and Creating
Print out your circuit board design and then place it on the blank board. Using an iron, heat the pieces until the ink transfers to the board and soak off the residual paper using tap water. Be gentle so that you don’t rub the ink off the board.
Use your etching solution and soak the board in it for around 45 minutes. Be careful with this solution, you don’t want to place it in a metal utensil, use plastic instead. Use gloves and tweezers when removing this from the solution and rinse it under the tap for a few minutes.
Finishing the Board
The final step for this is to clean off any leftover ink from your board. Take a toothbrush and ensure that there is no residue left on the board, as this could potentially impact their performance. From there, you want to drill in holes using the Dremel, removing any dust that is created.
Depending on what components you want to add to the board, you can get your solder and pieces ready. You can also continue to sand down the edges further to ensure that it fits within the system that you are creating.
Making your own printed circuit board can be fun and help you to progress within your project. If you want to create a system that suits your needs, then this can be a great way to go about it.
