Electronic design

developing an electronic system

Electronic design

Electronic design starts from the component layout specification. Also, it consists in the definition of interconnections and PCB technology.

Finally, component selection is formalized (BOM, Bill of Material), such as the circuit schematics and the layout of PCB traces (gerber file).

If the Electronc Systems is composed of multiple circuit boards, electronic design includes the description of the interconnection schemes, and the instructions for the wiring manufacturing. Adgenera develops electronic circuits tailored and suitable for any application. It selects the most valuable technology for the peculiar field of application, in order to ensure the maximum reliability.

Electronic design frameworks

Custom-designed electronic solutions can be found in many sectors, covering various fields of application and meeting Client needs. The most frequent requests are:

  • design “from the scratch”
  • miniaturization of an existing circuit board
  • cost Reduction
  • electronic board update, when components are no longer available
  • engineering a prototypal board, either partially or completely working
  • functional improvement (for example, adding a wireless interface)
  • performance improvement (for example, power consumption reduction)

Other elements increase the complexity of the electronic design:

  • legacy firmware for the previous version of board
  • need for a custom / legacy interface to other electronic existing systems
  • availability of the components on the market within a certain amount of time
  • project constraints due to standards or certifications

The steps of the Electronic Design

Electronic design aims to respond to the request of designing and producing electronic circuit boards.

First, the customer is interviewed on the characteristics of the electronic system to be designed..

The customer is actively involved to identify the best design choices.

This preliminary phase leads to the correct identification of development times and costs, allowing the customer to verify the compliance with his needs and to create a preliminary project planning.

Now the electronic scheme can be designed. Specific skills of our designers are applied to correctly select and size the components.

Once the scheme has been designed, the electronic components available on the market are selected. Then, they will be soldered to the electronic board during its production phase.

We select the most suitable package of components depending on the layout, the space available and the type of application.

This design phase leads a draft of the BOM (Bills of Materials) necessary to supply and solder the right components.

The electronic components chosen are placed on the board surface. Their positions strictly match design constraints principles to guarantee the correct functioning of the electronic system.

Usually several alternative arrangements are evaluated. Finally, the chosen one is the one that leads to the best result once the electronic card is produced.

Once the components are finally placed in the board, it is necessary to draw the connections (tracks) that appropriately connect the pins of the components themselves.

The tracks design needs to follow many rules and best practices: although there are infinite ways to connect the chosen components, only a few solutions guarantee a good quality card.

The preliminary electronic design project is ready: the first board samples are created to check the functionality and performance of the designed electronic system in the laboratory.

During the tests, the laboratory instrumentation verifies that each quantity measurable on the card corresponds to the value theoretically calculated during the electronic scheme design.
