➢Step descriptions:
✦Step 1:-Like always,we have printed the circuit on photo paper, and press it with iron.
✦Step 2:-Put it into the water and rub it softly, after this submerge it into ferric chloride, and shake it slowly around 15 to 50 mins.
✦Step 3:-This process will be completed, after this, we will wash it with water. We will remove the print with help of thinner.
✦Step 4:-Now make some holes.
✦Step 5:-After making the holes we will stick another print on the top, and remove it.
✦Step 6:-For better viewing, we can apply vegetable oil on it. And the PCB is ready.
✦Step 7:-Let’s start the mounting. First of all 2 resistance.
✦Step 8:-Solder and install all these parts below on the board:
1 AUX Socket 3.5mm
5 Capacitor 100uF
1 Capacitor 2200uf25v
3 Capacitor 470uf
2 Capacitor 0.001uF 102
4 Capacitor 0.1uF 104
3 Connector - Screw Terminal 2 Pin (5mm pitch)
1 Connector 2 Pin (2.54mm)
1 Connector 3 Pin (2.54mm)
4 Diode 4007
1 IC CD6283
1 Potentiometer- Dual 47K
1 Regulator IC 7805
1 Resistor 1/2 Watt 2.2 OHM
2 Resistors 1/4 Watt 150 OHM
2 Resistors 1/4 Watt 2.2 OHM
2 Resistors 1/4 Watt 22K
1 Resistors 1/4 Watt 560 OHM
✦Step 9:-Cutting the pins.
✦Step 10:-Before soldering we will apply liquid flux, then soldering.
✦Step 11:-.Attach a knob and a heatsink on ic.
✦Step 12:-Prepare a 12v 1amp transformer,connect it.
✦Step 13:-.Prepare 2 speaker boxes and connect.
✦Step 14:-This is our cable for connecting the phone through the aux connector, let’s connect the phone.
✦Step 15:-Play.
