UV Board Making Step.... (STEP 1)

STEP 1: Preparing circuit


This is the packaging of UV board








PCB circuit layout on transparent paper






a) On a transparent film,start your layout with transfer paper 
b) Print your circuit on white paper then copy on an acetate film 




This is UV box




c) Direct copy the circuit on transparent film by using duplicator 
d) Print out from computer plotter  
e) Prevent the printed transparent film from expose to sunlight after duplicating

UV Board Making Step.... (STEP 2)

STEP 2: Exposing 


Put the printed transparent PCB layout in center position on the board
a) Cut the board to a size you desired if necessary
b) Tear off the black protection film on the board




c) Expose the board in Exposure box for 60-90 seconds
d) Put your circuit layout on top then press a flat glass sheet as a top layer to make a good contact between the film and surface of board
e) Turn on the light for 8-10 minutes 
f) Good contact between the film and the board is very important

UV Board Making Step.... (STEP 3)

STEP 3: Etching 


Etching Tank
a) Etching the board in etching tank for 4-10 minutes
b) Pour enough etching solution (Ferric Chloride) into a plastic tray and immerse the board with artwork side up


After come out from the etching tank




c) Gently agitate the tray till the unwanted copper foil etched away and only the circuit pattern left
d) Rinse the board with plenty of water
e) 15-60 minutes maybe required to etch the board completely
f) The etching process is most effective if the solution is kept at a temperature of about 120-140F (50-60C) 


 
Here short video that taken when we doing the etching process

UV Board Making Step.... (STEP 4)

STEP 4: Developing




 





a) Put the whole pack of powder and one litre of water into a tray,agitate the tray till the powder is dissolved
b) Immerse the board completely
c) Agitate the board or the tray until the circuit is clear otherwise bare copper foil
d) Brush the board if necessary needed
e) Dry the board
f) Finish 



This is the continuous video from the previous video in step 3




This is how the board look like after complete all the process
