WEEK 4 ( etching process )

STEP 1

STEP 2

STEP 3

STEP 4

AIM

• To etching the both PCB board by using manually.
• To show the step of etching the PCB board.

RESULTS

• At the step 1, glossy paper has been used for this PCB board etching circuit. Set iron at the maximum temperature and rub smoothly until all of the ink at the glossy paper stick at the PCB board. This process will take around 15-30 minutes.

• At the step 2, the glossy paper will look as a picture above, thats mean all of the ink is stick properly on the PCB board. After that, the PCB board need to put on the warm water around 5 minutes to make sure the PCB board more sticky.

• At the step 3, the etching process will be make by using ferric chloride chemical. This chemical need to mix up with a hot water and sieve around 30 minutes to make sure only the copper side are left.

• At the step 4, after the etching process done, the PCB board need to rinse by using water before the scrub process has been made. The PCB board will look as the picture above and multimeter has been used to check the continuity all of the copper to make sure all of the connection is in good condition. PCB marker will be used when the connection on the board is not connect properly.

PLAN FOR THE NEXT WEEK

• To mount and solder the components
