Provide BOM recommendations for PCB component procurement
After checking the BOM list, entering the material procurement stage, it is usually necessary to first confirm the market inventory of active components, especially the new main ICs, MCUs, etc. of large brands. Due to the irreplaceability of active components, long delivery cycles from component factories, and high value of individual products, material procurement plays a crucial role in overall project delivery and cost control.
Problem 1: Shortage in the component market and long delivery cycles for component factories
Suggestion: It is normal for the new material to be out of stock within three years, but it can be tried within five years. If the original packaging is unopened and the storage environment is good, it can be used within five years. However, it is recommended to first make a sample to see if the tin plating is good, and ensure that the sample is OK before mass production.
Question 2: The material is an outdated product and an early project
Suggestion: Compared to outdated products, component factories update their materials, and new components can replace outdated products in terms of functionality, with lower power consumption and stronger performance. In addition to reading the specification sheet, we can also browse some website information, such as DIGIKEY, MOUSER, and other official websites that have many updated material tips for corresponding products.
Problem 3: Shortage of components and price increase
Suggestion: When encountering this problem in the procurement of active and passive components, they need to be handled separately. If encountering this problem in the procurement of active components, customers generally need to cooperate with PCBA manufacturers to provide alternative components or modify or adjust solutions.
If we encounter this problem when purchasing passive components, we can provide multiple well-known brands of passive components with the same parameters as substitutes, such as resistors, capacitors, inductors, etc. As for connectors, many of our domestic connectors can also meet the needs of customers' products, reduce procurement costs, accelerate delivery time, and stabilize product availability.
Meanwhile, in the process of continuous communication with customers, we can provide suggestions based on their future order needs and prepare some components in advance to cope with market fluctuations and material shortages.
Finally, as an engineer handling BOM and purchasing components, it is essential to have a basic knowledge of electronic components, be patient, understand the local component market situation, be proactive when purchasing components, adopt different negotiation strategies for components with different unit prices and quantities, and continuously accumulate high-quality supply channels.
