Our company, Shenzhen Jia Jinyuan Industrial Technology Co., Ltd., commissioned SGS-CSTC Standards Technical Services Co., Ltd. Shenzhen Branch to conduct a dedicated halogen test for our WTH model Solder Paste, with the corresponding report number: SZXEC26005331704. The sample was delivered to the laboratory on September 16, 2026, the testing period was from September 16 to September 20, and the report was officially issued on September 21, 2026.

The submitted sample for this test is WTH solder paste, which appears as a gray paste in physical form. The test was conducted in strict reference to the IEC 62321-3-2:2020 standard, using the C-IC combustion ion chromatography method. The test was completed through sample pretreatment, sample weighing, combustion absorption, and instrumental analysis in sequence, to quantitatively detect four halogen substances: fluorine, chlorine, bromine, and iodine.

According to the test results, all four halogen items, fluorine, chlorine, bromine, and iodine, were ND (not detected), with each content below the instrument method detection limit, indicating that the halogen indicators of this WTH solder paste meet the halogen-free control requirements.
