With the development of society and the progress of science and technology, the electronics industry has ushered in unprecedented development, and circuit design companies have sprung up. However, this is followed by confusion when customers choose circuit design companies. Faced with the offer of many circuit design companies, how to make a wise choice for customers has become an important task. In the process of circuit design, the selection of parts is particularly important.

The importance of part selection

Electrical engineering is both a science and an art. Circuit design is not based on guesswork, but on precise calculations. Engineers need to balance competing requirements in their work, including performance, cost, schedule, budget, power, and more. In circuit design, the selection of appropriate electronic components is very important.

PCB Part Selection Method

How to select PCB parts?

When selecting parts, first make sure that these parts can be adapted to the current project needs. In some cases, the choice of parts is relatively simple, taking into account factors such as cost. But in other cases, choosing a part can be more complicated.

For example, if you need a 470 ohm resistor, such components are relatively easy to find, and the main consideration is cost. But if you need a microcontroller with five USART buses, capacitive touch, and operating at about 1 microamp in sleep mode, you'll need to read and understand multiple manufacturers' technical data sheets to make sure you get the software toolchain you need, and the cost is within your budget.

Every part has its associated cost. It can be difficult to get price discounts when designing small projects or ordering 1, 10 or even 100 copies of boards. But if your board plans to produce 10,000, 100,000 or even 1,000,000 times, you can contract directly with the manufacturer and bypass the distributor, resulting in significant cost savings.

The life cycle of the part

It is important to note that every electronic part has a life cycle. When a new part is introduced, it may be warmly received, but over time, interest may wane or manufacturers will come up with more powerful alternatives. Eventually, the production of the original part will stop and you won't be able to continue using it in your design.

In general, in circuit design, choosing the right electronic components is a task that is both scientific and artistic. For circuit design companies, part selection requires a trade-off between performance, cost, availability and many other factors. Through careful study and judgment, we can ensure that the final circuit design achieves the desired effect.
