From cell phones, laptops and computers, printed circuit boards are the primary components of all electronic gadgets. Printed circuit board design services can provide help in designing printed circuit board design and high-speed printed circuit board designs.
Printed circuit board services can improve and optimise your current design for a cost-effective assembly. A perfect design will allow all the components of the electronic design to work perfectly and in good coordination with each other. Let’s have a look at what are the steps followed by printed circuit board service to prepare the design and layout of an electronic circuit.
1- Project Specification
The building of a printed circuit board starts with the writing of technical specifications of the project. A comprehensive specification enables all the designers that are involved in the designing process to understand every bit of the project and what the customer is expecting from them.
Project specifications is a detailed document that covers a lot of things like what are the technical requirements, deliverables, what skill sets are required, what type of tools and technologies will be needed, preliminary bills of materials (BOM) and their costs.
2- Schematic Design
Printed circuit board design connects all the components of an electronic device and this is actually called the design of the electric circuit. Schematic is the next step in the preparation of printed circuit boards after deciding the project specifications.
Schematic is also known as circuit diagram and clarifies the electrical connections between electrical components. It shows how the electricity will travel between the components. The modern techniques of preparing the schematic involve the use of CAD software. The most commonly used software is Altium Designer that flawlessly define modules and connectivity of different components.
3- Printed Circuit Board Layout
The next step is to prepare the layout of the printed circuit board. To start the process, the schematic is imported into the layout. The printed circuit board design services then place the component manually on the board to see how the paths are used by the components to connect with each other.
The signal integrity is analysed and electrical limitations are evaluated to ensure the safety of the board. DFM/DFA is used for minimal chances of revisions, low development costs and reduce time to market.
4- Fabrication and Testing
After receiving approval for the layout, printed circuit board services convert the documentation into the required format of the customer. The design requirements of each image of the circuit board are analysed. These documents are used by the manufacturers for the fabrication and assembly of the circuit board. In case the manufacturer has certain requirements, a 3D model of the electronic circuit can also be prepared. Both printed circuit board design services and fabrication stage are tested intensively.
5- Mass Production
Once a prototype is prepared and has been approved, the next step is production. For this, the files are prepared for mass production and complete assistance is provided to facilitates the manufacturing process. The testing of each printed circuit board is ensured by providing special software, hardware and testing procedures.
The printed circuit board services also provide technical assistance to the customers that can be provided during the warranty and after the expiration of the warranty period. BOM, 3D files, Gerber and technical manuals are prepared for the customer.
