PCB designing and development is very important in electronics as it gives freedom to use the electronics for a long period. PCB development includes a process called Etching. this method removes the unwanted copper from the circuit. this methods requires Fecl3 Chemical and we need the steer the bucket for 10 to 20 minutes which is a slow process. so we made a simple etching process machine which run on 6 volt system. we just need to put the chemical and thus it gives a PCB in time.
