Today I'm going to show you how to make your very own customized PCB (printed circuit board). All you need are some materials and tools like a: PCB board, A bottle of Ferric Chloride, A mini drill, A small container, A bottle of thinner and Some plastic tweezers. Making your own circuit board only takes a snap, what you need is 30-45 minutes of time. I thought of posting this Instructable since there are only few articles out here in the site about making a customized circuit board
It is so easy even a 12 year old kid can make one !!!! ^_^ !!!!!
P.C.B. (Printed Circuit Board)
What are PCBs ?PCB (Printed Circuit Board) is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper sheets laminated onto a non-conductive board. Components are connected through the conductive material below a non conductive board, the common conductive material used in packaged PCBs are usually copper, since copper is cheap and common.
Why Use Customized PCBs Instead of Ready Made Project Board?
First, because the board will be more compact because your design as well is made to be compact. Second, it's more convenient to use, since you can decide where to put space on your board. And last, the board will be stronger unlike those ready made project boards are full of holes everywhere, making ready made boards weaker.
How Do We Make Them ?Usually you print your circuit design indirectly to your board, you print it on a glossy paper, photo paper or magazine paper. Let me remind you that before you print you should use a laser printer or a photocopying machine, using of inkjet printer will not work. After you had printed your circuit board design you will iron the printed design over the copper side of the PCB, ironing it above the copper side of the board will transfer the ink, from the glossy paper to the PCB board. The ink serves as the protective layer to cover the copper part that shouldn't be etched. Then after transferring the ink to the PCB board you will have to dip the PCB board to a etching solution like Ferric Chloride for 15 minutes. After etching it you might have to rinse the PCB board with water to remove the etching solution. After rinsing it you should remove the remaining ink with thinner, to uncover the uneched copper part. After removing the ink you will need to dill holes for your components to be soldered on the board. And last but not least just solder your components of your customized board and your done!!!
How does the procedure work?Since the etching solution only works with metal and not with ink, you transfer ink to the copper side of the PCB be so that a certain pattern on your PCB board gets etched and the inked part doesn't
