Week 6 & 7 (FYP2) : Creating the PCB

Hi, sorry for late posting of the Week 6, because i was busy preparing for the Phase Test. So, i combined Week 6 and Week 7 under one post.

This week, i had create the PCB using layouts that i had designed using Altium Designer; and copper board. There were many step involved in creating the PCB.

Figure above shown the process of cutting the copper board. i bought an A4 sized copper board in Jalan Pasar for RM9.

Figure above shown the cutting process of the OHP sheet.After printing the PCB layout on a Overhead Projector (OHP) sheet, i cut it according to the size.

Align the OHP sheet which has the printed layout on the  copper board. Make sure the printed side was facing the copper side of the board.

Iron the OHP sheet onto the copper board. The heat applied by the iron, will cause the ink on the OHP sheet to stick on the copper board. Thus making the copper board look like the OHP sheet.

Dip the PCB into the Etching solution (Ferric Chloride solution, FeCl₃. The solution reacted with the unmasked copper, and removes the unwanted copper from the PCB. This process is called as Etching. The PCB was check every 10 minutes.

Now the PCB was carefully drilled, to make the holes, using drilling machine.

Picture above is the completed PCB.
