Introduction: Paper Circuit Board (P!.C.B)
Many small circuits like
MIC preamp , guitar preamp ,
FET booster , rain detector etc has few parts
We can use a hard paper tomake them
Here we see how to do that .....
Step 1: Draw in MsPaint
Make a small sketch of the layout in mspaint
Step 2: Draw on Paper and Glue Parts
Draw the parts on paper .
Cut leads short
glue with superglue
Note : dont put glue on pins /legs
After the glue dries
Scratch the pins with blade to remove oxides
Step 3: Ready an Enamelled 38SWG/28SWG
The wire will join all the connections
trick is not to cut the wire in small pieces
A)scratch one end .. join to the part/pin on paper PCB
B)select the length , dont cut ,scratch enamel off ,join ....finally cut
C)Tricky soldering if there is 3three or more lines to join
here just glue the wire and then solder
See the completed circuit is so small like 1cm square
Step 4: Conclusion: Place a Casing
Once the circuit works
Glue all the wires
Place the cute PCB(paper circuit board)
in a case to make it strong
you can glue it to the case no insulator needed
Eg bench power supply
guitar effect units
Although soldering is tricky it saves lot of time .
Mine is a capacitor tester in a 2cm X3cm Tictac
Only half of the can it took i can have 3 more circuits there :)
We have a be nice policy.
Please be positive and constructive.
