Printed Circuit Board – How is the assembly done?

It is not easy to fabricate circuit boards. Some gadget lovers like to design and create their own printed electrical plates, but they are not multifaceted like those finished by machines. Also, it takes a lot of time to make lots of such boards at home.

As soon as you melt the electronics on a printed circuit board, an assembly is prepared. However, the mounting of the electric plate is different compared to its manufacture. With the production of printed circuit boards, various procedures are involved, including the design of the boards and the prototype of the printed circuit board.

It is very important to assemble all the right devices and install them on the board before it is inserted into the electronic devices. Now the question that arises is this; what type of printed circuit board is installed on which device. Different electronic boards have different mounts involved depending on the device in which they are to be installed. There are two main types of manufacturing approaches involved in manufacturing PCB assembly:


  • Approach through the hole: In this approach, the devices are implanted into the holes
  • Surface Mounting Approach: In this approach, the devices are installed in the outer planes of the electronic board.

The only similarity between the two approaches is that the devices are installed on the printed circuit board with the help of a metal solder using electricity. The ability of the board decides how the appliances should be cast in the frame. In case of manufacturing more quantity of circuit board assemblies, it is always advisable to make use of machines. The positioning of the circuit in the machine is done by welding by wave, as well as by the use of reflux oven. The machine is placed with wave-welding or bulk-melting furnaces. In the case of small-scale production, one can always choose manual welding.

Sometimes both; hole approach and surface mount must be applied in a single assembly because some electronic components are obtained only in sets of holes, while others can only be obtained in surface mount assemblies. This is advantageous when both approaches are used during the assembly process.

The hole through the installation makes the electronics robust only in case they have some physical damage. However, it is best to use the surface mount approach when you are aware that any damage is less likely to happen. The surface mount approach uses less area on the electronic board.

Once the assembly process is complete, it is important to verify that the board is functioning properly and performs the necessary function. In case of failure of the printed circuit board, it is very easy to discover the source of the problem and replacement can be done.
