This post is especially for the beginners and hobbists. Its a great pain making huge circuits on bread boards and much more keeping them alive on them. Its good though in the start but when, its a matter of circuit with communication or clocks, u need noise free circuits. I remember trying UART for the first time and communicatig with the PC via RS232. It took us 3 days to figure out what went wrong. Our code was correct, written over many times, but still it didn't worked! And i guess the hardware was correct too.We finally decided to make a PCB. And it worked! But then what was wrong???
- No open or loose wires, which means proper connections.
- Atleast half of the noise due to wires was suppresses.
- It was easier to track down faults.
- Probability of working of project increased many folds.
1. Draw your layout using some PCB designing software (PCB EXPRESS (free of cost), EAGLE(Free for small boards), ULTRA ROUTE or anything that’s worth the money and you can lay your hands on.
2. Get its LASER print out on a cheap glossy sheet (my own method of cost effectiveness).
3. Put it upside down on to the copper plate.
4. Iron it for 3-4 minute.
5. Remove the sheet in one go.
Now you'll have a copper plate with black lines on it. Thats your circuit! Dip this in FeCl3 or H2O2
