The main items and steps of common component screening

conductcomponents and partsScreening is an important step in the design and manufacturing process of electronic products. Effective component screening can ensure product performance, reliability, and cost-effectiveness. The following are the main items and steps for component screening:

1. Functional requirements

· objectiveEnsure that the components meet the functional requirements of the design.

· contentCheck whether the basic functions and performance parameters of the components (such as voltage, current, frequency, gain, etc.) meet the design requirements.

2. technical specifications

· objectiveEnsure that the technical parameters of the components meet the requirements of the system design.

· contentIncluding operating temperature range, power consumption, packaging type, pin configuration, etc.

3. reliability

· objectiveEvaluate the reliability of components under different environmental conditions.

· contentView the reliability test results of components, such as temperature cycling, wet heat testing, vibration testing, etc.

4. Supply chain stability

· objectiveEnsure long-term supply of components to avoid production disruptions caused by stock shortages.

· contentEvaluate the production capacity, delivery time, and market reputation of suppliers.

5. cost

· objectiveControl the overall cost of the product.

· contentCompare the prices of different components, taking into account the purchase quantity and discounts for long-term cooperation.

6. compatibility

· objectiveEnsure compatibility between components and other circuits or systems.

· contentCheck the compatibility of components with existing designs, including electrical characteristics and mechanical interfaces.

7. Certification and Standards

· objectiveEnsure that components comply with relevant industry standards and certification requirements.

· contentCheck if the components meet the requirementsRoHS, REACH, UL, ISO and other standards.

8. technical support

· objectiveEnsure that necessary technical support is obtained during the design and production process.

· contentEvaluate the technical documents, reference designs, and technical support services provided by suppliers.

9. consistency of performance

· objectiveEnsure consistency in performance of components across different batches.

· contentReview the quality control and testing processes provided by the supplier and evaluate their consistency.

10. Sample testing

· objectiveVerify the performance of components through actual testing.

· contentObtain samples for functional testing, performance testing, and reliability testing to verify whether they meet design requirements.

summary

Component screening is a process that comprehensively considers multiple factors, including functionality, technical specifications, reliability, cost, and other aspects. Through systematic screening methods, it is possible to ensure the selection of the most suitable components, thereby improving the quality and reliability of the product.
