Step 1 - Appearance Inspection
For all the warehouse goods, we perform appearance inspection and make detailed inspection records.
• Manufacturers, manufacturers part numbers, quantity, date code and RoHS
• Packaging inspection: whether the packaging is intact/ complete, in compliance with the corresponding standards of MSL
• Marking inspection, consistency inspection, the original specifications and documentation check
• Material appearance inspection, dust conditions, whether the pin is deformed, whether the pin shows signs of oxidation
Step 2 - Engineers to Re-examination
All the materials provided by non-Tier 1 suppliers in the system should be re-examined by engineers.
• Review Appearance Inspection process
• Check the manufacturers label/marking and coding logo with reference to the quality control database
• Barcode scanning inspection
• Check with the original factory lot number, batch number, date code, and related wafer/packaging origins
• Electrical performance test
Step3 - Quality Testing
All the unidentified goods in the Engineer Re-examination process will go to the quality testing process and would be tested by the authoritative laboratories such as Whitehorse and CECC laboratories.
• Solderability testing
• D-CAP analysis
• X-RAY analysis
• XRF/EDX/EDS testing
