What is PCB Designing?
A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. Components capacitors, resistors or active devices are generally soldered on the PCB.
Why Learn PCB Designing?
Today, many of our daily appliances and equipment use electronics, sensors and sophisticated computer technologies. Circuit Designing & PCB Designing is an integral part of any Electronic Gadget or Robotics. If you know how to design any circuit & logic behind it then you can do any innovation with your creative ideas.
You might be surprised at what you can design - you just have to have a 'problem' to utilize your knowledge. Even with some basic knowledge you can do some pretty cool things. A lot can be done with some transistors, op amps and logic gates.
When designing a circuit, think about what you want it to achieve. Then how do you think the circuit will do this? Start simple. What power source will you be using? A 9V battery? Sketch it down.
Then what? A status led? Draw that down, but remember it needs a resistor to 'protect' it. Does the circuit need to count for a certain amount of time after some sort of trigger? If so, think what you can use. See how by taking little steps you can create your own circuit? It may not be a super-doper all-singing all-dancing circuit with a hundred ICs and crystals and bluetooth and all that stuff, but it's a circuit that you have made.
