PCB failures are the very disturbing reason for the failure of electrical products and appliances. The PCB board failure leads to damage of overall system and thus the device suddenly stops operations.

Therefore it is must that they should be checked for proper operation so that finally it would have a desired operation. The PCB boards development needs much inspection and done by prototyping of the boards which is the foremost sample checking.

What is circuit prototyping in PCB?

A test design of the original circuit that is done in temporary boards rather than PCB board is called circuit prototyping. The complex circuit needs to be tested first for faults and defects this is done by prototyping the circuit so that the faults can be detected before it is made a permanent PCB board so for this purpose circuit prototyping is an essential part.

Why is circuit prototyping important?

The PCB board once made can’t be modified or reconstructed so the effective inspection is to be done to verify the design and expect a good output so for this purpose prototyping plays a important role:

Following points highlights importance of circuit prototyping:

-It helps in locating the faulty parts of the connections
-It helps in assuring good output result

-Helps in gaining the ideas on the positive project outcomes
-It helps in correcting the faults and tracking the errors in the result
-The electronic devices, semiconductors and components can be tested
-Safety can be checked

Thus, it is very essential for assuring manufacturers on the PCB boards efficiency and results it gives. That’s why circuit prototyping is essential.

What are used to make circuit prototypes?

For circuit prototypes making different types of temporary boards are available in market that can be used for temporary circuit adjustment and testing. They function well as the PCB but can get destroyed or damaged soon and thus it’s not a permanent solution at all , though is very significant in circuit prototyping.

A common example is breadboard which are usually used in mini projects by students.

What are PCB prototyping board?

The PCB prototyping board are the ones that are used to prototype the circuit temporarily. It can be said as temporary adjustment of the circuit components and are assembled as per PCB design.

They hold the components through the holes their surface consists and make connection simpler so that faults can be detected easily and fixed. Later, on it is very difficult to locate and repair the permanent PCB boards so PCB prototyping board are very significant in minimizing defects,
This can be done with commonly available boards like:

(1)Bread Board
Breadboard are type of boards that is bread shaped structure containing different small holes and consists terminal strips to hold the circuit design components including processing components and bus strips to handle power or signal input and output usually consists two columns. Various systems can be prototyped using it. It doesn’t requires soldering at all.


It usually makes hand soldering fast. It has features easier than hand soldering through hole and can be very useful for PCB circuit prototyping. Its manufacturers distribute their own made jumper wires which are easy to install temporarily and use.


Originally developed in 1960s the board is very widely popular in circuit prototyping. It is not made for surface mount components. But many components can be placed on its track side. It is made up of insulating material. It has parallel copper strips on one side of it.

The wires are bent usually and then passed through the holes. Though, soldering is done on board it is not difficult to remove the solder and then reconstruct the design on the board thus, can be used for circuit prototyping.

They are also called DOT PCB. It is thin and rigid. It consists already drilled holes in it at different intervals. It is very fast and easy way to mount the components.

They consist of copper solid pads that makes prototyping simpler and easier. The connection can be made with wire wrap or can be done with point to point wiring phenomenon.

The usage of prototype circuit in PCBs

Prototype circuit is made according to design and circuit connection standard so that all components are mounted accordingly. They are then inspected simultaneously for minimizing faults and defects. It can minimize the dangers of defects. The defective PCB boards are very difficult to be repaired once damaged thus, it is essential to inspect by circuit prototyping.

The prototype circuit has a great significance

-It can be useful to detect faults
-It can help in correcting engineering faults
-Soldering needs not to be done so the process is quick for checking the correct results
-Defect free PCB can be assembled
-Can help in good output product design and development

The benefits to prototyping a PCB

-It minimizes the defects chances
-It helps in locating faults
-Saves time and amount that is needed is correcting damaged boards that are assembled without proper inspection.

-The output can be checked and thus can be modified for best result
-It minimizes the faults related to components and they can be inspected and replaced before permanent assembly.

-Easier as soldering needs not be done so quick testing can be done
-Assures a fault proof PCB design and development
-Device or appliances safety and quality can be assured
-Warranty can be guaranteed to customers on product devices.

When should prototyping be used?

Prototyping can be used when the circuits faults needs to be minimized. A testing is needed to check whether the design made is effective or not. SO, circuit prototyping allows testing without need of soldering or temporarily attaching components so, finally the output can be viewed and then defects can be minimized.

It helps in saving cost time and improving the product device quality. A fault proof assembled PCB can last long for years. Before releasing a final product prototyping is done in electronics companies that helps in correcting the defects and thus improve design quality.

What is prototyping with example?

Prototyping is simply testing the design and development output by a shorter process that is temporary so can be modified as per changes required.

A prototype is an example product before release of final product. Prototypes are made for testing and finding defects to minimize the problems that can appear later. Engineers check the quality and efficacy of device by a model device test. So prototyping is creating a model of the desired structured object or device.

Once the engineers or quality testers are assured they approve the product to be released by building its final form and changes are made as per the prototype testing has figured out.

For example for passing a exam we give test exams to be perfect for the boards thus, the test exams can be compared to prototype. Many companies first develop a prototype before finalizing a product. A robot is tested for its every operation simultaneously and then after final prototype approval it is ready to be launched.

So, PCB prototyping is foremost process before PCB assembly which helps in reducing chances of faults.

How do PCB prototype boards work?

The PCB prototype board like breadboard has its connection made through inbuilt holes that connects different components.

The components may not require soldering and thus, is a faster process. They are connected as per design through jumper wires. The jumper wires are most useful in prototyping as they make end to end connection between components and power supply is usually made through one of column in bread boards.

The boards are insulated properly with no chances of current leakage. The input and output connection are made and components added in between the process and are tested for accuracy, defects, and the result is verified as per the need. Prototyping allows the identification of defects and can lead to a quality board Development finally.

The circuit connection is made as per design instructions and tested accordingly, thus a fault proof PCB is then assembled with components and soldered permanently by through hole or surface mount process and is ready to be produced in large numbers to be used in specific devices.

Thus, PCB failures can lead to large damage thus, Prototyping allows the development of quality board for operation. It allows a proper inspection and quality checking at the same time so a great quality of boards can be manufactured,

Finally, so output can be acceptable and satisfying for the clients according to the need of the devices.
