The SGS Solder used on our production line is not just a matter of sticking a label; each batch comes with an original test report issued by SGS, with complete report number, sampling date, test method, and measured data. The production line QE can directly enter it into the ERP traceability system without needing to send samples for re-testing or wait for the supplier to supplement documents.

Test Items Cover Full-Chain Risk Points

The testing of SGS solder is not limited to whether the lead content is below 1000ppm, but simultaneously covers six restricted substances: cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. Among them, hexavalent chromium is determined using the EN ISO 3613 method, and polybrominated biphenyls and polybrominated diphenyl ethers are quantified using GC-MS, with the detection limit stably controlled within 5ppb, fully matching the stringent release standards of customers for automotive electronics and medical PCBA.

Reports and Physical Batches Are Strongly Bound and Cannot Be Separated

The unique QR code on the outer packaging of each roll of Solder Wire, when scanned, directly jumps to the SGS official website verification page, displaying the original report PDF corresponding to that batch, issue date, testing institution authorization number, and signed engineer information. Moreover, the report clearly marks that the sample comes from XX furnace number and XX casting batch of Jia Jinyuan factory, eliminating the phenomenon of report reuse or mixed batch swapping.

Traceability Response Time Compressed to Within 2 Hours During Production Line Abnormalities

Last Wednesday, Line A experienced consecutive soldering defects on OSP pads of three boards. We immediately retrieved the batch number of the SGS solder used during that shift, exported the corresponding report from the MES system within 15 minutes, confirmed that the active ingredient of the Flux was not out of tolerance and the halogen residue was 48ppm, far below the upper limit specified by IPC J-STD-004B. The problem was ultimately identified as being caused by stencil tension attenuation rather than the solder itself, avoiding production stoppage losses caused by suspending the entire batch of materials.

Automatic Verification Actions Embedded in Procurement Acceptance Process

Now, when the warehouse receives goods, it must use a PDA to scan the QR code on the outer box of the SGS solder. The system automatically compares three hard indicators: report validity period, completeness of test items, and compliance with limits. If any item fails, a red light warning is triggered and the warehousing process is frozen. Last year, two batches of abnormal incoming materials lacking hexavalent chromium test items were intercepted as a result, and all were returned to Jia Jinyuan for re-testing and supplementary reporting.

The environmental protection indicators of SGS solder are not just promises written on paper, but technical facts that can be retrieved in real time, cross-verified, and quickly reverse-inferred on the production line site for each batch. This implementable traceability is the strongest confidence in responding to customer flight audits and customs inspections.
