We pride ourselves on our meticulous component procurement and quality inspection process. This comprehensive approach ensures that we maintain high standards and deliver superior PCB assemblies to our clients. Our process is designed to optimize efficiency, ensure component authenticity, and guarantee the highest quality of final products.
1. Organize Bill of Materials (BOM)
The procurement process starts with organizing the Bill of Materials (BOM). This document lists all the components required for PCB assembly, including their specifications, quantities, and preferred suppliers. The BOM is the foundation for all subsequent procurement activities.
2. Components EQ Checking
Next, we perform an Engineering Qualification (EQ) check on the components listed in the BOM. This involves verifying the components' specifications, compatibility, and compliance with industry standards. The EQ check ensures that all components meet the necessary requirements for the intended application.
3. EQ Feedback
The results of the EQ check are compiled and provided as feedback. Any discrepancies or issues identified during the EQ check are addressed at this stage. This feedback loop is crucial for resolving potential problems early in the process.
4. Obtain Approval Confirmation
Once the EQ feedback has been reviewed and any issues resolved, we seek approval confirmation from relevant stakeholders. This step ensures that all parties are in agreement with the component choices and that the project can proceed without further delays.
5. Procurement
With approval in hand, the procurement team places orders for the components. Core components are sourced directly from the original manufacturer or authorized distributors such as Digikey or Mouser to ensure authenticity and quality.
6. Incoming Components Inspection
Upon receiving the components, our quality control team conducts a thorough inspection. This inspection includes checking the packaging, part number, description, footprint, silkscreen, and date code to verify that the components match the specifications listed in the BOM.
7. Sampling Inspection
In addition to the initial inspection, we perform a sampling inspection on a subset of the received components. This step involves testing and analyzing the components to ensure they meet our quality standards.
8. IQC Storage
Components that pass the sampling inspection are moved to IQC (Incoming Quality Control) storage. This secure storage area is designed to protect components from environmental factors and ensure they remain in pristine condition until needed for assembly.
9. Qualified Confirmation
Once the components are in IQC storage, they receive qualified confirmation. This status indicates that the components have passed all necessary inspections and are ready for use in the assembly process.
10. Rejection Handling
Any components that fail inspection are rejected and returned to the supplier. This step ensures that only high-quality components are used in our PCB assemblies, maintaining the integrity of our final products.
11. Arrangement of SMT Assembly
With all components verified and stored, we proceed to arrange for Surface-Mount Technology (SMT) assembly. This involves preparing the components and PCBs for the assembly process, ensuring everything is in place for efficient and accurate production.
