The successive revisions of the EU RoHS Directive continue to impact the global solder industry, driving solder products toward more environmentally friendly development.
Published: 2026-08-24Jiajinyuan lead-free flux has RoHS and SGS third-party test reports. Tested by authoritative third-party laboratories, the product's hazardous substances are controlled within standard limits and comply with the environmental protection specifications of the electronics manufacturing industry. This test report can be used for customer factory audit, foreign trade project document submission, and internal archiving.
Published: 2026-08-24The lead-free solder wire produced by JJY has obtained RoHS and SGS test certificates. This certificate is an important proof of product compliance. Through strict testing by a third-party laboratory, the content of hazardous substances is controlled, and the finished products meet environmental protection control requirements. Possessing this test report can prove that the hazardous substance indicators of our company's solder products meet
Published: 2026-08-24RoHS is a mandatory environmental protection directive issued by the EU for the electronic and electrical industry. As a globally recognized green access standard for electronic manufacturing, it primarily restricts the use of hazardous substances such as lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE).
Published: 2026-08-24Jiajinyuan lead-free PCB cleaning solvent has RoHS and SGS third-party test reports. The reports are issued by authoritative institutions after testing, strictly restricting various harmful substances, and the product meets the environmental protection standards of the electronics industry. This test certificate can be used for customer factory audits, foreign trade customs declaration and project data archiving, proving that the harmful substances of the PCB cleaning solvent comply with
Published: 2026-08-24RoHS solder fully meets the requirements of EU environmental directives. Jiajinyuan lead-free solder paste achieves stable printing of 0.3mm fine-pitch QFN on SMT production lines, with a wetting angle of less than 35° after reflow and a void rate of less than 15%. When paired with solder wires and bars of the same system, it can ensure consistent process windows for wave soldering and manual soldering, avoiding poor wetting or abnormal thickening of the IMC layer caused by mixed use.

All Jiajinyuan solder paste products continue to pass the dynamic and effective control of RoHS, halogen-free, SGS and ISO systems, covering more than ten types of细分 scenarios such as high temperature, medium temperature, low temperature and laser welding. Among them, 8MQP/5RQ series solder paste achieves nearly 100% solder climbing rate for QFN/DFN, 8M9P/
Published: 2024-02-01The compliance of solder paste with RoHS, REACH, and halogen regulations directly affects the market access of exported products. SGS solder paste inspection reports must strictly correspond to each batch of physical solder paste. Jia Jinyuan's production line achieves 100% traceability through double-person verification of batch numbers, inspection dates, and consistency with the inkjet codes on solder paste cans, along with synchronized archiving of electronic versions of original SGS solder paste inspection reports, to avoid returning entire batches of PCBA due to mismatched reports.
Published: 2019-02-14RoHS solder strictly complies with the EU RoHS environmental directive, completely eliminating six categories of hazardous substances including lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. It is suitable for high-reliability production lines such as consumer electronics, medical equipment, and automotive electronics. In Jia Jinyuan's actual SMT mass production, it has been verified that it has stable wettability at a peak temperature of 245°C, a void rate lower than 3.2%, and the thickness of the solder joint IMC layer is controlled within the range of 1.8~2.4μm.
