From Dream to Reality: PCB Prototype Assembly Services 2020 | GREATPCB |

PCBs are fundamental to the functioning of almost all electronic devices today. However, before starting with full-fledged production, the PCBs are checked for their functionality. Once the final product has been made and if it fails to perform as desired, it may prove to be very costly. So, having a prototype printed circuit board is essential for every electronic gadget because prototyping helps engineers to test the functioning of the PCBs in the design phase. Several runs of prototypes are carried out for testing a single function before commencing with more complicated designing. This helps to identify any flaws and make necessary corrections in the initial stages of the production process.

Choosing the right assembler

In order to make prototypes for your printed circuit board solutions, you require an assembler to promptly develop high-quality prototypes which will give you an idea about the functioning of the final product. A renowned PCB prototype services provider like Great PCB offers speedy and accurate prototyping services. The following post will update you about the various stages of printed circuit board prototyping.

  • Conceiving the idea

At this stage, the electronic device manufacturer thinks about developing an existing device further or launching a new one. They share their idea with providers of PCB prototype services through Great PCB and discuss things like how the PC board can improve the functioning of the device further and what the size of the unit and the circuit board should be are planned.

  • Designing the schematics

When you already have a basic idea about the size of the board and things that can be done with it, you can design the schematics for developing the prototypes of the PCBs. The components, layering, thickness of the board, panel and grid size and budget are considered. For designing purpose, a PCB design software suite can be used. After the first schematic has been designed, it is checked for any defects following corrections if any. The electronic design is then converted into a netlist.

  • Assembling

Once the schematics have been agreed upon, the circuit board is assembled for creating the prototype. To ensure efficiency and effectiveness of the circuit board, all the settings are properly adjusted. Latest types of equipment are used so that the components can be connected with utmost precision and speed.

  • Testing

When the circuit board has been assembled, it is tested to check if it is working as per the client’s specification and design. If any inconsistency or error is detected, it is corrected before finally handing over to the client. The client conducts further tests to check if this is the thing they are looking for before placing any bulk order.

  • Modification

Even if the initial prototyping has been approved, certain areas may be identified later which can be further improved or modified to make the end product better. To do so, one needs to go back to the initial design phase and make necessary changes before all the printed circuit boards are finally assembled.GREATPCB SMT LIMITED Conclusion

Although the prototype is accepted for large scale production and the final product has reached the end-user, the research still continues in order to keep up with emerging technologies. The prototype-assembly service providers are there to transform your dreams and new ideas into reality as they develop circuit board prototypes for the new products.

PCB Designing and Manufacturing Service Online

The printed circuit boards are made up of copper and depending upon the requirements of the board, the copper is plated to a substrate. To get a secure fit it needs to be lined and bonded together.

Designing process

Designing the board is the most important step before you start with the manufacturing process. Based upon these blueprints you will be able to start with the designing. The design that is required for the various materials of the PCB manufacturing service will be done through software.

The design is printed

A special printer that is available at the PCB manufacturing service of GREATPCB SMT LIMITED will provide you providing the print. This will also provide you with a film where all the details of the board will be shown.

 

Preparing the Substrate

From this step, the formation of the structure will take place. The substrate is a material that will hold the structure along with the components. The copper is first pre-bonded on both the sides of the layer. Then it is etched so that the design is available from the printed films.

Print the inner layers

To laminate the body of the structure the design is first printed. A photo-reactive chemical that is used in the photosensitive film will start hardening when this will be exposed to an ultraviolet ray. The blueprint will help in the aligning process by drilling the holes.

 

Ultraviolet Light

After the alignment is done, the ultraviolet rays will harden the photoresist. The light will in carrying out the process. After it gets harden the board will then be washed in an alkaline solution so that the excess photoresist can be eliminated.

Remove the unwanted copper

The unwanted copper that is attached to the board needs to be removed. A chemical solution will help you in this process. They will take out the excess copper from the board and the photoresist remain at the same place.

Inspecting

The board is then checked for alignment and in this process, the holes will help. This will help in placing the inner as well as outer layers easily. A pin will help in keeping the layers together.

Lamination of the layers

As the layers are fused, the boards will try to take the shape. As the laminating process begins the metal clamps will help in laminating the layers. This is done with the help of copper foil and also with resin.

Pressing the Layers

To press the layers a mechanical press will be applied on the board and along with that, the pins are also punched so that it is properly aligned. These pins are removed depending upon the requirement if needed. If everything is proper then the board will go for the laminating press where pressure and heat will be applied.

Drilling

The holes are drilled through the layers with the help of the computer-guided drill so that it can expose the inner panels as substrate and the extra copper has been shredded.

This is how the designing, as well as the manufacturing process, is carried out.
