Is it difficult for circuit design companies to select parts? Now teach you

Is it diffICult for circuit design companies to select parts? Now teach you


The design of printed circuit board is based on the circuit schematic diagram to realize the functions required by the circuit designer. The design of printed circuit board mainly refers to layout design, which needs to consider the layout of external connections. The optimal layout of internal electronIC components, the optimal layout of metal wiring and through-hole, electromagnetic protection, heat dissipation and other factors. Excellent layout design can save production costs and achieve good circuit performance and heat dissipation.


With the development of society and the progress of science and technology. The development of the electronic industry is also unprecedented, and there are more and more circuit design companies, which makes customers more and more efforts in selecting circuit design companies. When customers get a scheme, they may find many circuit design companies to quote. If the quotation of the circuit design company exceeds the customer's budget, it will be difficult to obtain customer recognition, Thus, the selection of electronic components has become the top priority of circuit design companies.

How to select parts

Electrical engineering is both science and art. The science of circuit design - component values are calculated, not guessed. The current job is to balance all the competitive requirements of the job: engineers must generally balance performance, project costs, schedules, link budgets, power budgets, parts availability, etc. Circuit board assembly, circuit board design and processing factory explain how difficult it is for circuit design companies to select parts? Now I will teach you how to select parts.


The parts must be suitable for the work at hand. In some cases, it is more difficult to determine that a part is suitable for a particular job, while in other cases, it is easier to determine.


For example, if you need a 470 resistor, finding one is easy, and the limiting factor is usually just cost. However, if you need a microcontroller with 5 USART buses, capacitive touch and working at~1 µ A in sleep mode, you will have to read (and understand) a lot of data tables from many manufacturers - ensure that you have access to the software tool chain required for programming the microcontroller, and then ensure that the cost meets your budget requirements.


Each part has a related cost. When you design a SMAll project like ours, or order 1, 10 or even 100 copies of a specific circuit board design, it is difficult to negotiate a price discount. However, when the circuit board you designed will be manufactured 10k, 100k or even 1 million times, you can bypass the distributor and directly sign a contract with the manufacturer to save a lot of costs.


ElectronIC parts can only be manufactured for such a long time. After the introduction of new parts, it will become more and more popular in many years. Eventually, interest in parts will diminish, or manufacturers will introduce more powerful replacement parts. Either way, the original part will stop production and you will no longer be able to use it in your design.
