WEEK 6

In week 6 Our holiday is finished. Time to focus for our project , my partner and i also plan to do etching. So we go to PCB Laboratory Workshop to do it at 1st floor.

1) We put the print circuit trasparent at the UV Box. After that, we put the UV board at the top print circuit and do the process 60s.

2) After that, we put the develop and pour and mix with the water then shake it. This process want to make the circuit appear at UV board.

3) Thus, after done shake, we transfer the PCB into etching tank and do the operation for 4-5 minutes.

4) Lastly,after the process and operation already done, we use sand paper to clean the circuit board. Finally, the circuit appear.

-My friend which help me doing the develop etching PCB togethers. Thanks you my friends. (^_^)
