The flow chart illustrates the process of manufacturing the circuit bords.
Overall, the process involves in eight main stages, beginning with collection of raw circuit board materials, ending with packaging and distribution to factories.
To begin with, raw materials are collected for treatment. Initially, the materials are cut into the required sizes, then spraying with fire retardant. Then, the materials are cleaned into water. Then, the main process is started production of circuit-board.
In the fourth stage, integrated circuit (ICs) are automatically attached and soldered onto board. The fifth step involves visual inspection and quality control testing. At this point, there are two possible outcomes: if the chips are failed the inspection and quality checks, they are discarded. However, it is passed the evolution, they proceed to the final testing. At the last stage of process, it completely passed all testing, they are packed for distribution to industries.
