For the export of 5G equipment solder, a full set of inspection documents compliant with IEC 61190-1-1, JIS Z 3284 and RoHS 2.0 requirements must be provided simultaneously, covering solder composition reports, melting point curves, wettability tests, halogen content, intermetallic compound thickness and tin whisker growth assessment. All export batches of Jia Jinyuan are subject to full-item third-party testing by SGS or CTI in accordance with customer-specified standards, with original data attached.
Published: 2016-11-08BGA chip reballing repair relies on precise reballing processes. Jiajinyuan's dedicated solder paste works in synergy with matching solder balls to ensure solder joint coplanarity, tensile strength, and void rate meet standards. This solution has been verified on multiple production lines to stably pass 500 cycles of -40℃~125℃ thermal shock without defects such as solder bridging, cold solder joints, or ball misalignment.

Although adding antioxidants to solder bars can significantly delay oxidation reactions and reduce the amount of dross generated during high-temperature molten soldering, it cannot completely eliminate dross formation due to multiple production line variables such as wave soldering temperature fluctuations, flux residue decomposition, molten solder agitation intensity, and alloy composition segregation. There are clear process boundaries for the effectiveness of solder oxidation resistance.
Published: 2013-06-07ASEAN foreign trade solder has passed the full-item testing of the RoHS Directive and multiple physical, chemical and toxicity tests conducted by SGS. The contents of restricted substances such as lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers are all lower than the mandatory thresholds of the EU and mainstream ASEAN countries. With complete batch factory inspection reports and certificates of origin, it can be directly used for the access filing of SMT production lines in electronic foundries in Vietnam, Thailand, Malaysia and other countries.
Published: 2011-11-12RoHS solder SGS testing certification is a mandatory threshold for export-oriented EU electronic assembly production lines. Jiajinyuan RoHS solder has passed SGS's full set of heavy metal and organic substance testing, with all six items—lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers—meeting the standards. Customs clearance documents include the original SGS report, Declaration of Conformity, Material Safety Data Sheet, and batch factory inspection records, and the complete set of documents can be directly used for customs declaration and customer factory audits.
Published: 2011-04-11High-wettability solder paste directly determines solder climb rate and void control in the soldering of fine-pitch devices such as QFN/DFN. Domestic solder paste brand Jiajinyuan covers the full spectrum from no-clean ROL0 to water-washable ORH1. Its 8MQP/5RQ series achieves nearly 100% solder climb, while the 8M9P/5RR series has an extremely low void rate and is suitable for automotive lighting. The selection of SMT solder paste must match the coupling relationship among alloy melting point, flux activity, and cleaning process.
