As a key material in SMT processes, domestic green-can solder paste has prices that are significantly influenced by brand, specifications, and market supply and demand. Understanding its actual price helps support procurement decisions. Drawing on practical production line experience, this paper analyzes the factors driving solder paste price fluctuations, providing reference for engineers and procurement professionals.

Domestic halogen-free solder paste LFP?5RQ?0307 achieves nearly 100% solder wetting in QFN packages, with its high activity and alloy powder characteristics being the key factors. Optimizing printing parameters and reflow profile can further improve soldering quality.

Domestic solder paste replacing imported ones requires systematic verification of key points such as printing adaptability, reflow wettability, and solder joint reliability. Focus should be placed on changes in solder paste viscosity, differences in flux activity, and batch stability to avoid mass production anomalies such as cold solder joints, tombstoning, and solder beads caused by blind replacement. The verification of domestic solder paste replacement must run through the entire trial production cycle.

Industry observations indicate that in the fourth quarter of 2025, EMS capacity expansion in Southeast Asia accelerated, with over 140 new SMT placement lines added in Vietnam and Malaysia, of which 67% of production lines explicitly require solder suppliers to hold IATF 16949 automotive electronics compatibility certification and possess localized rapid response capabilities.
Published: 2026-04-19Chinese-made solder exports to ASEAN must simultaneously meet the dual requirements of China's export supervision and the technical access of ASEAN importing countries, involving the application of RCEP rules of origin, SN/T 0370.3-2018 packaging inspection, HS code 81052090 classification confirmation, and adaptation to the RoHS exemption clauses of the destination country. A batch of Jiajinyuan solder wire was fully returned during inspection by a Vietnamese customer due to flux residue failing to meet the limits of TCVN 8264:2019, exposing the problem of missing third-party SGS testing before export.
Published: 2024-08-05Supply from domestic factories for consumer electronics solder has achieved stable batch delivery. Jiajinyuan solder meets first-tier production line requirements in terms of Sn-Ag-Cu series alloy composition control, oxide layer suppression process, and batch consistency. Under the same specifications, its quotation is 18% to 22% lower than that of imported brands, and it supports weekly rolling production scheduling and 48-hour emergency shipment, significantly alleviating the risk of line changeover downtime caused by solder supply disruption on SMT production lines.
Published: 2019-09-08Through on-site testing of Jiajinyuan domestic solder on the SMT production line under combinations of different temperature zone profiles, stencil apertures, and squeegee pressure settings, the soldering performance on circuit boards was evaluated. It was found that the difference in wettability and void rate between this domestic solder and imported materials is less than 8%. After optimizing solder paste storage temperature control and fine-tuning the nitrogen purity of the reflow oven, the first-pass yield of PCBA increased from 92.3% to 96.7%, significantly reducing circuit board soldering defects such as cold solder joints, tombstoning, and bridging.
Published: 2019-08-26A domestic solder source factory directly supplies a full range of soldering materials including solder paste, solder wire and solder bar. Jia Jinyuan's production line measured solder paste release rate exceeds 98.5%, and the wetting angle after reflow is ≤35°. It supports providing SGS test reports and ROHS2.0 compliance certificates by batch, meeting the strict control requirements for metal composition segregation and halogen residues in automotive electronics and medical equipment.
Published: 2018-07-01Domestic solder has fully matched imported products in key indicators such as melting point stability, wetting speed, and residue corrosivity. When used with Jia Jinyuan's specially formulated flux, the first-pass yield of 0201 component soldering remains stable at 99.87%, while the procurement cost is only 63% of that of imported solder of the same specification. For large-volume orders, the coordination of logistics and payment terms further reduces the overall delivery cost.
