When a problem occurs or repair is required, you can quickly locate the source and replacement of the problematic component by viewing the BOM list, thereby improving the efficiency and quality of after-sales service.
The BOM list plays a vital role in the procurement of electronic components. By using the BOM list, purchasing personnel can ensure the integrity of components, improve efficiency, control costs, manage quality and track and trace, thereby providing strong guarantee for the production and operation of the enterprise.
How do PCB assembly manufacturers store electronic components in warehouses?
When electronic components of PCB assembly manufacturers are stored in warehouses, they need to follow certain specifications and requirements to ensure the quality and reliability of the components. Here are some common storage requirements:
Classified storage: Classify and store components according to their types, specifications, characteristics, etc. For example, electronic components such as resistors, capacitors, and diodes can be placed in different areas or shelves for easy management and search.
Label identification: Each component should be labeled, and the label should include the component’s model, specification, quantity and other information. This avoids confusion and incorrect use of components.
Moisture-proof and dust-proof: Electronic components are easily affected by moisture and dust, so the warehouse should be kept dry, clean, and equipped with measures such as dust removal and moisture-proofing. Some components that are sensitive to humidity should be stored in a dry box or protected with moisture-proof agents.
Sun protection and high temperature protection: Some electronic components will be affected by sunlight and high temperature, so warehouses should have sun protection measures to prevent direct sunlight from shining on the components. At the same time, the temperature of the warehouse should be controlled within a certain range to avoid damage to components caused by excessive temperatures.
Fire and explosion prevention: Some electronic components are flammable and explosive, so the warehouse should have fire and explosion prevention measures, such as installing smoke alarms, fire extinguishers, etc.
Regular inspection: Warehouse managers should regularly inspect electronic components, including quantity, quality, expiration date, etc. Some components that are approaching their expiration date should be processed or replaced in time.
Record management: Warehouse managers should record and manage the purchase, storage, and delivery of electronic components to facilitate tracking and tracing.
PCB assembly manufacturers need to strictly abide by specifications and requirements when storing electronic components to ensure the quality and reliability of components. At the same time, regular inspections and record management are required to avoid errors and losses.
Detailed steps for purchasing electronic components
The detailed steps for purchasing electronic components usually include the following links:
Clarify purchasing needs
First of all, it is necessary to clarify the model, quantity, quality and other requirements of the components that need to be purchased. This is to ensure that the purchased components meet actual needs and avoid blind purchasing and waste of resources.
Find the right supplier
Find suppliers that meet your procurement needs through search engines, procurement websites, exhibitions, etc. When selecting a supplier, factors such as the supplier’s strength, credibility, and quality assurance need to be considered.
Develop purchasing plan
Develop a detailed procurement plan based on procurement needs and suitable suppliers. The procurement plan usually includes component model, description, quantity, purchase price, delivery time, contact person, contact information, delivery address and other information. This can integrate supplier resources, reduce procurement costs, and improve procurement efficiency.
Initiate an inquiry or quote
Initiate price inquiries to multiple suppliers through email, phone calls, online inquiry, etc., and obtain quotations from each supplier. Compare the price and quality of different suppliers and choose the most suitable one.
signing the contract
Sign electronic component purchase contracts with selected suppliers. The contract should clearly include important terms such as the name, model, quantity, price, delivery method and time, and quality requirements of the purchased items. Signing a contract is conducive to the protection of the rights and interests of both parties and a good start for cooperation. Be sure to ensure that procurement-related regulations, standards, and quality requirements are spelled out in the contract.
Supervise warehouse management
After the purchase is completed, it is necessary to supervise the warehouse purchase and inventory management. Ensure that the storage method, environment, and fire safety of components meet requirements. Avoid the situation of “three days of fishing and two days of drying the net” and handle warehouse management issues in a timely manner.
Check into the database
Usually, purchased electronic components are subject to strict quality control and need to be inspected and stored in the warehouse. Compare the warehousing materials with the purchasing list to confirm that the quality of the materials is correct before warehousing. After passing the acceptance, the items will be put into the warehouse management system and marked, and the inventory changes of items, raw materials and finished products can be tracked at any time.
These steps are the basic process for purchasing electronic components, but they may differ depending on the actual purchasing situation. For example, if the purchase quantity is large or the cooperation is long-term, a bidding or inquiry process may be required; if the purchased components are special or complex, more technical communication and negotiation may be required. Therefore, in actual procurement, the procurement process should be flexibly adjusted and optimized according to specific circumstances.
