Addressing the frequent solder bridging, shorting, and solder ball defects of solder paste that occur during SMT placement of devices with 0.3~0.4mm fine-pitch pins, this paper proposes a rapid, reproducible optimization pathway for solder paste printing parameters based on real production line cases. It covers key control points including stencil aperture design, squeegee pressure and speed matching, and solder paste pre-warming and stirring specifications, and emphasizes the decisive influence of solder paste printing stability on the subsequent formation of solder balls during reflow soldering.
Published: 2014-04-07To address the common issue of solder collapse during the soldering of fine-pitch components such as 0.4mm pitch QFN and 0.3mm CSP, we recommend a range of field-tested anti-collapse solder pastes that cater to specific requirements including zero halogen, low voiding, and high solder climb. Among them, the 8MNTTP/5RNTT series achieves a solder climb rate of over 98% with transparent residue during reflow soldering on mobile phone motherboards, while the 8M9P/5RR series delivers a void rate of less than 3% on automotive LED lighting boards. All products use T4/T5 grade fine-pitch alloy powder and rosin-based flux vehicles, making them truly triple-positioned products that are anti-collapse solder pastes, fine-pitch solder pastes, and domestic solder pastes suitable for domestic production lines.
Published: 2009-05-07To meet stringent requirements in high-density PCB soldering such as fine pitch, high solder climb rate, and low void rate, multiple domestic halogen-free, lead-free high-temperature solder pastes compatible with T3/T4/T5 grade fine powder solder pastes are recommended, covering high-activity scenarios for QFN/DFN, precision placement in communications and consumer electronics, low-void thermal management for automotive lamps, and special models for laser dispensing. All products use 0307/305 alloy powders with a measured melting point of 217–227℃, balancing printability, wettability, and residue transparency.
