Everyone at some point experienced the idea of making a better gadget or device than is on the market, and a few do start creating circuits if only in order to learn how electronics work.

The design process is fairly simple and similar to a great many other project structures.


Determining the work being accomplished: Since every circuit is made for a purpose, whether it be educational, entertainment or practical, the goal of the circuit to be designed will be the first thing that should e determined. With respect to the complexity with the task, the project may be subdivided into individual functions that will come together to accomplish said task. Selecting components: Now that you have the functionality figured out, you need to select the best and necessary components to construct the circuit. At this point will still be inside the design stage, no components are ordered just yet, just the datasheets and specifications from the components must design the circuit or subcircuit. This step is important, since all of the tolerances and characteristics from the working project has to be considered. Will the circuit be used in heat? Is it expected to resist mechanical stress (as in falling, shaking, etc)? The components chosen have to fit these traits as well as the electrical needs with the project, including current draw, which if the circuit is to be powered by batteries can be a major design issue. Schematic Design: In this stage the electronic circuits are designed with their corresponding schematic diagrams. This can be used as documentation plus a guide for implementation, since the design inside the schematic will be the the one that may ultimately will probably be converted to a real circuit board. This can be one of the most challenging steps of electronics design, since several kinds of analysis should be made in order for the circuit to work as intended. Those analysis require a certain amount of technical knowledge and experience since often even effortlessly analysis correct, experience can help you find situations that could potentially damage or increase the risk for circuit malfunction. Circuit Board Design: Given that the important part the circuit has been designed and represented using the schematic, the next thing is to create the circuit board the location where the actual components will be soldered. There are many automated tools to make circuit boards having a schematic. Manual design is very difficult, with big projects with lots of components it might become a extremely hard task, especially if space is a concern. Prototyping, Testing and Corrections: Another extremely important part of pcb design is prototyping and testing. Analysis and simulation sometimes gives erroneous or inaccurate as a result of external circumstances that could happen to be overlook during analysis such as mains hum, RF interference or other events created within the circuit for example thermal noise, inductive and capacitive coupling and others. Prototyping and testing allows you to find those hidden characteristics with the circuit, to be able to incorporate inside the design before massive production. All of this assists in easing costs since it is easier to discard one unsuccessful prototype than it is to withdraw a complete shipment which could contain up to countless units. Every one of the steps can be revisited as required, since the function or characteristics with the circuit may alteration of the midst of the design, or the proposed design is way too complex or would require a lot of cash or time for you to create or design.
