Electronics design

Electronics design plays a key role in building the desired functionalities of a device and ensuring that it works under the planned operating conditions.

Objectives of electronics design

As a result of the electronics design, the equipment manufacturer should have information on the necessary electrical connections and the electronics needed to implement them. In addition, electronics design should pay special attention to the availability of components and the manufacturability of equipment.

The objectives of electronics design are to plan electronics for the device that

  • Works as desired
  • Operates under the required conditions (temperature, humidity, vibration, etc.)
  • Tolerates anticipated disturbances (power surges, wireless data transmission, etc.)
  • Operates in accordance with related standards and official regulations
  • Uses components with secure availability
  • Can be designed and manufactured cost-effectively, including circuit boards and their assembly

The tasks of an electronics designer

The tasks of an electronics designer include:

  • Identifying the electronics requirements of the device
  • Finding the appropriate components for the device
  • Design of circuit diagram, i.e. electrical connections of a device
  • Designing the positioning of a circuit board or components as based on a circuit diagram
  • Functionality testing
  • Cost optimization in the form of component selections, for example

Considerations for electronics design

The design of electronics takes into account the requirements set by customers, users and the authorities on equipment. In addition to these, mechanics, the operating conditions of the device and its software as well as, e.g., the availability of components present their own challenges to the design work.


Design and mechanics

The design and mechanics of the devices also set requirements for electronics design. The device housing may limit the size and shape of the circuit board. Any connectors must be located both in the housing and in the circuit board at the same point. If the device utilizes wireless data transfer, it must have data transfer components and antennas.


Conditions of use

The housing and electronics must operate under the required conditions, in which case the design must take, e.g., the following into account: large thermal ranges, water resistance, and operation when the device is in motion. In addition, the device may have batteries or must operate with various types of utility power.


Software requirements

Electronics play a particularly big role in the operation of software on devices. For example, the amount of memory required is estimated on the basis of information provided by software developers. In some devices, the internal memory of processors and microcontrollers may be sufficient, but sometimes additional memory is required which can be supplemented, e.g., by the use of processors and microcontrollers such as RAM, Flash, eMMC or the SD memory card format.


Component and PCB selections

Devices can often apply components similar to those used in the manufacturer's previous devices, which simplifies logistics and facilitates lower prices as well as, in the case of microcontrollers, easier software development.

In addition to their features and performance, the choice of components used in the device depends on availability, delivery times and price. In order to ensure deliveries and maintain price levels, it often makes sense to use components sold by several component manufacturers.

When designing electronics, you also need to know the performance of the production of PCB manufacturers and component assembly, as well as possible limitations. If production is unable to manufacture the equipment according to plan, the plan must be changed or the manufacture carried out elsewhere.
