WEEK 9

Etching to complete PCB.

After designing the PCB using Ares it’s time to do the etching process to complete the PCB board. Figure 2.18 below show the etching process using toner transfer method to the board. There are many way to etching the PCB but to cut cost in this final year project used toner transfer method. After finish the etching the board can be solder all the component to the board.

Figure above show the toner have been transferred to the bottom layer that is copper layer using an iron. After transfer the toner, the etching poses can be start. Figure bellow show the etching process to remove uncover copper layer using ferric chloride.
