Do the PCB fabrication and Drilling process

Even though I already make the circuit using the strip board, the circuit cannot be function as usual.. The light cannot be dim.. It can only on and off.. So, I decided to try to do the circuit using PCB and test whether the circuit can work as planned or not..

And this is a few step in etching and drilling the board..


This is the PCB UV board when we open the cover of the board


The circuit is printed by using laser jet printer on the transparency paper. The circuit is tab on the UV board an seal it with the tape but make sure the tape doesn't cover the circuit..


Put the UV board that already tab with the transparency into the UV box to print the circuit by using the UV technology on the board.


This box is to remove the green layer of the board and only left the layer of the circuit.. To make this box function, need to put the circuit inside the net given and push both green button on the left of this box..


After about 3 minutes, take it out from the box and the result you can see as in the picture above..


Then wash the circuit using a water to make sure that the chemical from the box is totally removed..


Place the board to the etching net carefully and make sure that it not cover the circuit that printed on the board..


Place the board inside the etching box and close the cover of the etching machine..


Set the etching machine to 5 minutes and press the yellow button for start the machine.. Then wait for 5 minutes.. But please make sure that ON the etching machine by switch ON the power supply and push both green button on the machine..


After wait about 5 minutes, the machine will stop and place it out from the etching net and wash it again..


That's the result when the copper are gone..


This me with my circuit.. But there still have one more step.. You need to dip the board into the tinner to remove the green layer.. If not, you cannot solder the component on your board...


Then, the next state, we all go for drilling the PCB to make the hole so that it can place the component on this board.. And for your information, this is my first time in drilling things so I need to read a manual and ask for help in using this drilling device.. hehehe... Its quite fun you know..


This is my picture in drilling the board.. My hand is shaking badly because of the drilling device so I need my friend to hold the PCB..
