My experience makes the PCB board

In this article I will share the knowledge I am in making PCB board (circuit board) in a manufacturing robot I do I make my own sensors on the robot, robot sensors I have made the Proximity sensor or proximity sensor using 2 pieces of LED, in addition to I've made an intelligent system that I gave the name Smart Lock, a tool that is used as a safety lock on the motor. until now i still develop because there are still many shortcomings.
Okay back to our topic is how to make circuit boards. Before making the first circuit board that we have to do them
1. What kind of device that we will make
2. What are the electronic components needed to make the devices.at this stage we need to understand the characteristics of electronic components that will be used to assemble the device. this is necessary because if we are wrong to use the electronic components of the device we will later make are not the result that it will not even run
3.Membuat schematic designThis is usually known as a blue print, the schematic relationship between the electronic components described in detail and this may be a reference when the device that we created later have problems.
4. convert a schematic into a PCB designHaving ascertained the schematic is correct next step is to make the PCB design, usually in software to make the PCB provided a feature to convert schematic to PCB design. One of them that I use is to use software Diptrace

5. Print the PCB design to PCB boardThere are various techniques for print design to the PCB board. Yanng one of the techniques I use is to print the PCB design to a sheet of photographic paper and then I put that there is a PCB design surface and then heating it with iron, with the heating technique, the design will be glued to the PCB board

6. Dissolving the PCB board with FeCl3 (ferry chloride)Once the design is attached to the PCB board dissolves the board next to the ferry chloride chemicals, these chemicals serve to dissolve the copper, so copper is not closed design will dissolve.
7. Installing electronic componentsafter the PCB board so then we put electronic components.
