How to Optimize PCB Component Sourcing Process?
PCB (printed circuit board) embedded active and passive components are crucial components of electronic devices and are closely related to electronic component procurement. In the design and manufacturing process of the equipment, the correct selection and procurement of these components not only affects the functional realization of the product, but also directly relates to cost control, production efficiency and the stability of the supply chain.
1. Product Design Requirements and Procurement Strategies
Active components: such as integrated circuits (ICs), transistors, diodes, etc., usually require power to activate their functions and can control or process signals. These components need to be purchased according to the functional requirements of the product design. Designers need to select appropriate active components according to circuit requirements and then determine the procurement list.
Passive components: such as resistors, capacitors, inductors, etc., these components are mainly used to control current, voltage or frequency to support the stability and function of the circuit. Passive component procurement usually depends on design specifications and functional requirements.
In PCB embedded design, whether it is active or passive components, the design team will select and determine the specific electronic components required according to the characteristics of the product. Therefore, the procurement team needs to plan and execute procurement strategies based on design documents and bill of materials (BOM).
2. Procurement Cycle and Production Plan
Active components often have higher technical requirements and production cycles, especially high-performance integrated circuits, chips, etc. The design team needs to communicate with suppliers in advance to ensure that there is enough time for bulk purchases and avoid affecting production plans due to insufficient supply.
Passive components are usually relatively simple to purchase because they are usually standardized components with short procurement cycles and flexible inventory management. The procurement of passive components can usually be replenished regularly through long-term suppliers.
3. Supply Chain Management and Inventory Management
For active and passive components, procurement personnel must ensure timely supply according to production needs. This requires procurement personnel to have clear inventory management and keep in close contact with suppliers, especially for active components with long procurement cycles.
Global supply chain: Some special active components (such as specific models of microprocessors, dedicated ICs) may need to be purchased from international suppliers, which requires procurement personnel to have a global perspective and do a good job of supply chain risk management to ensure that product design is not affected by component shortages.
4. Cost Control
Active components are usually more expensive, so when purchasing, you need to focus on price trends, suppliers' bargaining power, and whether there is enough inventory to cope with price fluctuations.
Although passive components have a lower unit price, large-scale procurement needs may account for a large proportion of the overall procurement cost, so procurement personnel are also required to make reasonable plans in terms of quantity.
5. Quality Control and Certification
For active components (such as ICs, microprocessors, etc.), the procurement department needs to ensure that they meet specific quality standards, such as RoHS certification, ISO certification, etc., to ensure the reliability and compliance of electronic equipment.
Passive components usually have high quality requirements, especially key components such as resistors and capacitors. When purchasing, it is necessary to ensure that their durability and stability meet the design requirements.
6. Supplier Management and Partnership
When purchasing active and passive components, the selection of suppliers is crucial. For active components, procurement personnel may need to maintain long-term partnerships with multiple technology suppliers to ensure stable supply. For passive components, it is equally important to choose suppliers with global distribution capabilities and stable delivery times.
Conclusion
PCB embedded components directly affect the design, manufacturing and cost control of electronic products. The electronic component procurement team needs to work closely with the design team to ensure that the purchased electronic components can meet the functional requirements of the product, while controlling costs, ensuring quality and optimizing supply chain management. During the procurement process, the procurement strategy of active and passive components, inventory management, supplier selection, etc. will directly affect the final production efficiency and product delivery time.
