PCB Development Chem Test



















Last night i did some test with the chemicals which is used to develop PCB. For test i used piece of copper plated PCB sheet around 2 inch, and drew a simple circuit from a water proof pen and this circuit will detect infrared signal. For that i used a surface mount(SMD) LM358. I used surface mount chip because i want to make the circuits compact than now.
Even though i used a SMD chip i used normal 1/4 watt resistors in my circuit cause this time i did not order for the SMD resistors and stuffs. This was just a test for the chemicals that i have so the test is perfect. Chemicals are good to go for other developments. In my robo, the circuits will be surface mount ones.
This week i will do some positives to burn from chemical. Then it will look like an original circuit.
