Pls how will I insert some chips on the board and how will I create the bus connection
Most professional circuit boards and buses are printed on a board. They are designed either with software and languages such as VHDL https://en.wikipedia.org/wiki/VHDL or a simple breadboard https://www.amazon.com/SunFounder-Basic-… If you need to repair an existing board with bad chips, you need to have soldering tools and a lot of skill and hand/eye coordination.
