ASEAN foreign trade solder is designed specifically for small and medium-sized export orders, supports small-batch trial orders starting from 5kg, and is paired with JJY's proprietary logistics channels and localized technical response to ensure a first trial production pass rate of over 92%. It can later be seamlessly switched to stable monthly delivery at the 20-ton level, truly addressing the pain points of Southeast Asian customers such as difficult early-stage verification and slow batch switching.
Published: 2013-02-21Regarding the component drop-off issue during large-size device placement, the rheological properties and metal content of solder paste directly affect print formation and tack retention. Solder paste for placement needs to balance thixotropic index, slump rate, and room-temperature tack. The proportion of rosin matrix, type of activator, and particle size distribution of spherical solder powder in the solder paste formulation jointly determine the displacement resistance of devices during the placement stage.
Published: 2012-01-28To address the issues of solder paste collapse and excessive reflow void rate easily caused by the large copper foil and large pad structures of energy storage power boards, this paper is based on 20 years of measured experience on the Jiajinyuan production line, focuses on the matching of key parameters for solder paste selection, emphasizes that solder paste for large pads requires coordinated control of high thixotropic index and medium viscosity, and low-void solder paste must meet the synchronization between the flux volatilization curve and the thermal response of high heat capacity substrates, with the core focus on the wetting and spreading stability of solder paste under thick copper design.
Published: 2010-08-03The direct supply model from domestic factories for solder auxiliary materials significantly reduces intermediate costs. Jiajinyuan's full range of solder auxiliary materials, including solder paste, flux, and cleaning agents, supports orders starting from 100kg. The unit price for bulk purchases is 18% to 25% lower than that of traders, and the delivery cycle is shortened to within 7 working days, meeting the needs of high-frequency replenishment and urgent changeovers on SMT production lines.
Published: 2010-05-25Insufficient solder is a frequently occurring soldering defect in SMT production lines, especially prominent on large pad designs and PCBs with copper thickness of 2oz or above. Its essence is the combined effect of decreased solder paste transfer rate and insufficient wetting during the printing, placement, and reflow stages, requiring coordinated intervention across multiple links such as stencil aperture, squeegee pressure, peak temperature of the reflow profile, and nitrogen purity.
Published: 2009-02-24For 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.
