● Independent and controllable: The electronic components industry is also developing in the direction of independent and controllable, reducing dependence on external supply, so as to better protect national security and interests.
● Intelligence: With the continuous development of artificial intelligence, Internet of Things and other technologies, intelligence has become an important trend in the electronic components industry, and electronic components products will be more intelligent in the future and can better serve human life and industrial development.
● Environmental protection: The electronic components industry is also developing in the direction of greening, environmental protection and sustainable development have become a global consensus, and the electronic components industry also needs to strengthen environmental protection in all aspects of product design, production and recycling to achieve sustainable development.
The steps of the electronic component procurement
① Determine the demand: First of all, you need to clarify the model, types(resistors, capacitors, diodes or transistors), specification, quantity and other needs of the electronic components to be purchased, which can be determined according to your own application scenarios and design requirements.
② Find suppliers: You can find suppliers through search engines, electronic components trading platforms, electronic components mall, etc., and you can choose suppliers with reliable quality and reasonable prices through the comparison of multiple suppliers.

③ Inquiry and negotiation: You can initiate an inquiry to the supplier to understand the price, delivery time, quality and other information, and negotiate according to your own needs.
④ Place an order: After determining the supplier, price, delivery time and other information, you can place an order to make a purchase.
⑤ Payment and delivery: After payment, the electronic components supplier will ship the goods according to the agreed delivery period, and the goods need to be inspected and confirmed after receiving the goods.
The possible problems encountered when components procurement
● Counterfeit products
There are a large number of counterfeit components on the market, which are often cheap but of poor quality and can cause circuit failure or danger.
● Obsolete products
Some components may be obsolete and no longer manufactured by the manufacturer, but are still available on the market. If these components are purchased, they may lead to obsolescence of the design and affect the performance and reliability of the product.
● Inconsistent rated parameters
The performance parameters of the components are usually listed in the data sheet, and if the parameters of the purchased components do not meet the design requirements, it may cause the circuit to be unstable or not working properly.
● Bad batches
Due to variations in the manufacturing process, components of the same model may have different batches, and the performance of different batches may vary. If you purchase a bad batch of components, it may cause circuit instability or performance degradation.
● No suitable spare parts
In circuit design, it is common to spare critical components in case they fail. Without the right spare parts, failure can lead to production stalls and increased costs.
The suggestions for purchasing components
－Ensure that you buy genuine products and avoid counterfeit products;
－Pay attention to the production cycle of components and try to avoid buying outdated products;
－Confirm that the performance parameters of the components meet the design requirements;
－Understand the differences between different batches of components before purchasing;
－Suitable spare parts are available in case of component failure.
It should be noted that low price does not necessarily mean bad quality, but quality and reliability cannot be sacrificed in pursuit of low price. In order to avoid these pitfalls, it is recommended to choose a reliable supplier when purchasing components, ensure that the quality and performance of components meet specifications, try to avoid obsolete products, and stock suitable spare parts in case they are needed.
Factors and principles to consider when selecting components
● Parameter requirements
First of all, it is necessary to clarify the parameters required by electronic components, including voltage, current, frequency, temperature and other parameters. Determine the required parameter range according to the system requirements, and select the components that meet the requirements.
● Environmental adaptability
Elctronic components should be well used in various use environments, especially in harsh special environments such as humidity, sand, and high altitude.
● Reliability
Electronic components need to have a certain degree of reliability during use, and there should be no abnormal situation. Therefore, the life, temperature characteristics, vibration characteristics, etc. of components need to be considered in the selection process to ensure their reliability.
● Serviceability
It should be considered whether it is convenient to install, disassemble, replace and its tools required.
● Cost
Cost is one of the important factors in selection, and it is necessary to select electronic components with suitable prices under the premise of meeting system requirements.
● Packaging form
According to the actual application needs, select the appropriate packaging form. Common package forms include DIP, SMD, BGA, etc.
● Supply reliability
Choose reliable suppliers and brands to ensure the reliability and quality of components.
● Compatibility
When designing the system, it is necessary to consider the compatibility between components to avoid incompatibilities between different electronic components.
● Maintenance guarantee
When selecting electronic components, you need to consider maintenance guarantee, and choose components with perfect technical support and after-sales service, so that problems can be solved in time.
Other principles include:
1. The selected components are widely used and verified, and try not to use uncommon chips to reduce development risks.
2. In the case of similar functions, performance and utilization rates, try to choose electronic components with better prices to reduce costs.
3. Try to choose components that are easy to buy and have a short supply cycle.
4. Try to choose components that will not be discontinued in the foreseeable time.
5. Try to choose pin-to-pin compatible chip brand components.
6. Try to choose components that have been used in old products before.
7. Try to use all the functions and pins of the components.
Conclusion
In the manufacturing process of electronic products like PCB, a large number of electronic components need to be purchased, and these components need to meet the requirements of product design, including performance, specifications, reliability, quality and other requirements. The correct and effective selection and use of electronic components is an important task to improve the reliability level of electronic products.
The purchase of components needs to consider the supplier’s credibility, price, delivery time, after-sales service and other factors to ensure that the product manufacturing task can be completed on time and with quality. When purchasing components, be careful not to covet low prices and ignore quality and reliability to avoid affecting the quality and performance of products.
