LFP?5RTS?0307 translucent residual solder paste demonstrates stable performance in medium solder fillet formation mass production for QFN/DFN packages, offers good process adaptability, and its no-clean feature significantly reduces post-processing costs, making it suitable for high-density electronic manufacturing scenarios.
Published: 2026-08-28To address common issues such as cold soldering, poor wetting, and solder beads that frequently occur in the high-volume production of consumer electronics motherboards with OSP boards, this solution is based on measured production line data from Jia Jinyuan, focusing on four key measures: stencil aperture optimization, dynamic nitrogen concentration control, reflow oven temperature zone gradient matching, and AOI false alarm rate reduction. It stably improves the first-pass yield of OSP board soldering to 99.23%, with a single-line daily output exceeding 8500 units.
Published: 2020-02-17Daily routine inspection of reflow soldering production lines is the core line of defense against batch defects. Through systematic checks of rail parallelism, nitrogen purity, deviations between actual and set temperatures in each temperature zone, chain speed stability, and cooling section wind speed every shift, over 90% of typical defects such as cold solder joints, tombstoning, and cold soldering can be intercepted in advance, avoiding batch rework caused by single-point failures.
Published: 2016-03-28Consumer electronics solder places extremely high demands on batch consistency, thixotropy, and reflow performance of solder paste in SMT placement production lines. By optimizing the sphericity and particle size distribution of metal powder and strictly controlling the volatilization rate of flux, Jiajinyuan solder paste achieves continuous 30-day CPK ≥ 1.33 on mass production lines with a daily output of one million points, effectively reducing the rate of typical defects such as bridging, cold solder joints, and solder balls.
Published: 2012-01-09To address the challenge of solder bead control in SMT mass production, we recommend multiple domestic solder pastes validated on production lines, covering scenarios such as high-activity QFN solder climbing, halogen-free automotive lighting, laser welding, and water washing. By optimizing the alloy powder type, halogen content, and rosin system synergy, the probability of solder bead formation is reduced, meeting the triple demands of solder bead control, SMT solder paste stability, and domestic solder paste substitution and upgrading.
Published: 2009-05-21For high-volume SMT production lines, the quality stability of domestic solder paste directly determines the first pass yield and rework cost. The 8MQP/5RQ series achieves nearly 100% solder wetting rate for QFN packages, with both halogen indicators below 1500ppm; the 8M9P/5RR series is halogen-free with an extremely low void rate, making it suitable for high-heat scenarios such as automotive lighting. These mass-produced solder pastes have been validated at multiple leading EMS manufacturers for over 6 consecutive months with no batch-related failures. Solder paste selection for SMT must match the reflow profile window and device pad design. Domestic solder paste has evolved from being usable to being reliable.
Published: 2009-05-03For mass production scenarios in large SMT factories, this report analyzes the real adaptation logic of domestic solder paste under key working conditions such as high solder climbing rate, low void, zero halogen, water washing compatibility, and laser welding. Combined with the alloy powder types, halogen content and typical applications of 12 main series including 8MQP/5RQ, 8M9P/5RR, 5RLJ, it provides directly implementable process benchmarking basis for solder paste selection in large-scale mass production.
Published: 2009-02-02Covers solder paste requirements across the entire stage from R&D prototyping to mass production. Domestic solder paste brand Jia Jinyuan offers 15 specialized product series, ranging from zero-halogen ROL0 grade 8M9P/5RR solder paste for automotive lighting, to 5RG solder paste made with ultra-low-temperature In52Sn48 alloy, and further to the 5RLJ series compatible with laser jet valves. The full-stage solder paste solution supports near-100% wetting rate for QFN, extremely low void rate, water-wash compatibility, and direct soldering on stainless steel and aluminum materials, truly enabling single-vendor coordination and seamless switching for SMT solder paste selection.
